Indigo Browser Alternatives: Check the Paper Trail

Start with what is verifiable, because the two Indigos are easy to conflate and the internet does it constantly.

indigobrowser.com is live. It returns HTTP 200, resolves on Cloudflare nameservers (alexandra.ns.cloudflare.com, kirk.ns.cloudflare.com), and sells an antidetect browser for multi-accounting. Its headline reads "Антидетект браузер Indigo" and the page title is "Indigo антидетект браузер, мультиаккаунтинг и арбитраж". The interface language is picked in JavaScript from navigator.language: the site's own script sets currentLang = userLang.startsWith('ru') ? 'ru' : 'en', with a full English string table shipped in the same file. There is no separate /en/ URL, which returns 404, so the English version exists only as client-side text swapping.

The other Indigo is a name from Multilogin's history, and this is where I have to stop short. Multilogin's current properties do not mention Indigo at all: not on multilogin.com, not on its Multilogin X page, not in the knowledge-base article I read. What Multilogin's own documentation does name is its two browser engines. The article "how to use mimic and stealthfox" on multiloginx.helpjuice.com describes Mimic as "Chrome-based" and "Actively supported and improved", and Stealthfox as "Firefox-based", "legacy", and "no longer the main development focus", noting that Stealthfox "stays on its final core version 146".

Those are the same two engine names indigobrowser.com advertises. Its homepage puts "Браузер Stealthfox / 146 ядро" and "Браузер Mimic / 148 ядро" directly under the hero, and its feature table lists "Профили Mimic и Stealthfox". The Stealthfox number is identical to the terminal version Multilogin documents.

I am reporting that correspondence, not explaining it. Neither vendor's own pages say the two products are related, and I found no primary source describing a rebrand, a split or a sister-brand arrangement. Third-party reviews assert one; I could not confirm it, and the Internet Archive was offline when I tried to read Multilogin's historical pages, so treat any claim about the relationship between these two products as unverified. If you are after the Multilogin side of the name, the Multilogin alternatives breakdown covers that product on its own terms.

Telling them apart takes five seconds once you know what to look at:

The generation naming is worth a second look. Both products ship an "X" and a "6". That is a genuinely confusing coincidence for anyone reading a forum thread about "migrating from 6 to X" without knowing which vendor is meant.

Taking the live product on its own merits, here is what its pages state. The plan grid is rendered client-side, so the figures below come from the price table inside the site's own script/script.js, cross-checked against the static feature table in the page markup. All amounts are EUR, and the page notes that VAT may apply in some countries.

The Business tier is a ladder, not a single plan: the same price object runs from 300 profiles at €159 up to 10,000 profiles at €1,509 a month, with the annual equivalent at €980.85. Every annual figure in the file is exactly 65% of its monthly counterpart, a flat 35% off at all 25 tiers, which is a cleaner discount curve than most vendors in this category publish. A separate Enterprise block is hard-coded in the HTML as "От €300 в месяц", from €300 per month, which sits oddly inside a Business ladder that already passes €300 at the 1,000-profile step.

Two quirks fall out of that grid. The 10-day trial carries 50 profiles, five times what the €9 PRO 10 plan allows and the same as PRO 50, so trialists get a roomier product than the entry tier they are being sold. And the marketing copy above the grid promises "5 GB трафика доступны вам абсолютно бесплатно", 5GB of traffic free, while the plan table allocates 1GB on PRO 10 and reaches 5GB only at PRO 100.

Capability-wise the product is credible. It runs two engines, Chromium-derived Mimic and Firefox-derived Stealthfox. It offers local and encrypted cloud profile storage, Android mobile profile emulation from a desktop, team roles and permissions, built-in residential proxies drawn from what the page describes as more than 150 countries, and an API with Selenium, Playwright and Puppeteer support. One automation constraint is stated plainly in the feature table and is easy to miss: "Playwright (только Mimic)", Playwright works with the Mimic engine only, alongside "Selenium Hardened" and "Puppeteer Hardened".

Its own documentation also sets out the difference between the two generations. Indigo 6 is desktop-only, stores profiles in the cloud only, exposes the API on custom plans only, and starts at €100 a month. Indigo X adds a web interface, local storage, API access on every plan, built-in proxies, a fourth team role, multiple workspaces and selective profile import and export, starting at €9. That €9 figure appears independently in the comparison doc and in the pricing script, which is the only Indigo price I can corroborate from two sources.

Treat the promotional numbers differently. "99,98% аптайм", "7-летний опыт" (seven years of development experience) and "самого низкого процента обнаружения" (the lowest detection rate) are the vendor's own claims, published without method or measurement. I did not test detection rates for this post, and no figure in this category should be read as established fact unless someone shows you the harness that produced it. Our note on how antidetect browsers actually handle fingerprints explains why vendor detection percentages are close to unfalsifiable.

Feature grids in this category all look the same because every vendor ships the same checklist. What separates them operationally is whether you can find out what changed, when, without asking. A fingerprint browser is a security product whose value decays: Chromium and Firefox ship a new major roughly every four weeks, and a profile running an engine several majors behind the real browser population is a profile wearing a fingerprint nobody else has.

So the test for this post is narrow and checkable:

1. Is there a public changelog or release-notes page, reachable without a login?
2. Does its newest entry carry a date, and how old is that date today?
3. Does any entry name the actual engine build, so you can tell which Chromium or Firefox you are running?
4. Can you start a trial and migrate your own data without a human in the loop?

Applied to indigobrowser.com, that test returns a result I did not expect. The product is clearly shipping, but its published record is not keeping up, and three timestamps on its own properties disagree.

The changelog has no 2026 entries. Its documentation at faq.indigobrowser.com/releases lists twelve entries. The newest is dated 08.22.2025, and the oldest is the Indigo X official release. Every entry is dated 2025. Worth noting as a reading caution: the page mixes date formats, so 26.06.2025 can only be day-first while 08.22.2025 can only be month-first. Either way, nothing on the page is from this year.

The homepage is ahead of the changelog. The newest cores named in those release notes are Mimic 139 and Stealthfox 141. The homepage today advertises Mimic core 148 and Stealthfox core 146. Nine Chromium majors separate the product from its own documentation of the product.

The fingerprint database timestamp predates the product. Under the hero, the homepage prints "Последнее обновление базы отпечатков / 12.12.2024 15:15", the last update to the fingerprint database. Per the vendor's own changelog, Indigo X was officially released on 01.05.2025. The freshness widget on the front page is stamped earlier than the launch of the thing it is describing.

Then there is the documentation site itself. faq.indigobrowser.com/sitemap.xml contains 131 URLs, and all 131 of them point at your-docusaurus-site.example.com, the placeholder domain that ships in an unconfigured Docusaurus install. Not one uses the real hostname:

curl -s https://faq.indigobrowser.com/sitemap.xml \
  | grep -o '<loc>[^<]*</loc>' | wc -l          # 131
curl -s https://faq.indigobrowser.com/sitemap.xml \
  | grep -c 'your-docusaurus-site.example.com'  # 131
curl -s https://faq.indigobrowser.com/sitemap.xml \
  | grep -c 'indigobrowser.com'                 # 0

The self-serve half of the test is weaker still. The pricing card and the feature table both say 10 days of trial; the homepage FAQ says "у нас доступен пробный период на 7 дней", seven days, and that you should message support to get it. The Indigo 6 to Indigo X migration is in the same state: the homepage FAQ says the migration tool is "на последнем этапе тестировки перед запуском", in its final testing stage before launch, and points you at support, while the documentation's own Migration FAQ page is live but reads "Coming Soon", explaining that "We are currently preparing a comprehensive FAQ to help you transition smoothly from Indigo 6 to Indigo X." The comparison page lists profile migration among features "being redesigned for Indigo X". Support runs through a Telegram bot, t.me/indigosupport_bot.

None of that makes the browser bad. It makes the paperwork unreliable, which is a different and narrower complaint. If you run ten profiles for yourself, you will probably never care. If you run 300 and need to tell a client which engine build touched their ad account last Tuesday, you have no document to point at.

Here is the same four-part test applied to every candidate I checked, read on 9 October 2026. I ran a nameserver and HTTP check on each domain first; all resolved to ordinary commercial nameservers and returned 200.

The Nstbrowser row is the reason I trust this test. It is a well-known, actively marketed product, and its published release notes are a year staler than Indigo's. A test that only ever flattered the vendors I was about to recommend would not be worth running. Two names you will see in every other list on this topic, Incogniton and MoreLogin, are absent for a duller reason: I could not find a public dated changelog on either site, so I have nothing to score them on rather than a bad score to report.

The five that follow are the ones this axis selects, in the order the test ranks them.

Octo publishes two changelogs instead of one, and that distinction is exactly what the test is looking for. docs.octobrowser.net/changelog/octo-browser-changelog/ tracks the application: Octo Browser 3.1 on 07.09.2026, 3.0 on 07.07.2026, 2.10 on 10.02.2026, back through 2.8 on 21.10.2025. A second page tracks the engine alone: the Octium changelog records "Обновление ядра до 155 версии Chromium", core updated to Chromium 155, dated 8 October 2026, with 154 on 24 September and 153 on 10 September.

Two dated series mean you can answer the question Indigo's documentation cannot: which engine build am I on, and when did it land. The cadence in that series is roughly a fortnight per Chromium major, which tracks upstream closely.

For an Indigo user specifically, the fit is close. Octo's docs ship in Russian as well as English and Portuguese, so the language that makes indigobrowser.com comfortable is not lost. Profiles are cloud-stored and encrypted, with access from multiple devices. API access starts at the Base tier, with rate limits rising by plan. Published monthly pricing runs Lite €10 for 3 profiles, Starter €29 for 30, Base €79 for 200, Team €169 for 600 with 6 members, Advanced €329, and term discounts of 10%, 20% and 30% at three, six and twelve months. Billing is in EUR, which keeps the comparison with Indigo honest.

Two caveats. Octo is cloud-first, so if you specifically chose Indigo X for local profile storage, you are giving that up; see our notes on cloud antidetect browsers for what that trade actually costs. And the free trial is two days on a promo code, which is thin next to Indigo's ten. The comparison that matters is €79 for 200 profiles against €79 for 100, at the same price in the same currency.

If what bothers you about Indigo is that you cannot see what changed, the strongest available answer is a product where the change history is the product. Camoufox is open source, and every claim in this paragraph came from GitHub's API rather than a marketing page.

Read on 9 October 2026: latest release v156.0.1-beta.36, published 6 October 2026, with beta.35 on 5 October and beta.34 on 3 October. The repository's last push was 8 October 2026, the most recent commit being "Remove old sponsor". It carries 12,428 stars, is licensed MPL-2.0, and is not archived. The Python wrapper on PyPI is at 0.5.8, released 6 October 2026, MIT-licensed, supporting Python 3.10 through 3.15. Three releases in four days is not a maintenance claim I am repeating from somewhere; it is a list of timestamps anyone can re-read.

The engine point is the sharper one. Camoufox is built on Firefox 156. Stealthfox, the Firefox engine Indigo advertises, sits at core 146, and Multilogin's documentation describes 146 as its final version. Ten Firefox majors separate them. If your workflow needs Firefox rather than Chromium, that gap is the whole argument.

Camoufox's own description of its method, quoted as its claim and not as a measurement, is that it "modifies fingerprint data at the C++ implementation level, not via JavaScript injection which leaves detectable traces", and that "every property (navigator, WebGL, screen, fonts, WebRTC, and more) is intercepted before it reaches the page". Fingerprints come from fpgen, which generates device characteristics matching statistical distributions in real traffic.

Install and launch are short. The [geoip] extra is the one the project recommends whenever proxies are in play, because it derives latitude, longitude, timezone, country and locale from the exit IP:

pip install -U "camoufox[geoip]"
camoufox fetch

from camoufox.sync_api import Camoufox

PROXY = {
    "server": "http://gateway.sparkproxy.io:11000",
    "username": "YOUR_SPARKPROXY_USER",
    "password": "YOUR_SPARKPROXY_PASS",
}

# geoip=True makes Camoufox resolve the exit IP and align timezone,
# locale and geolocation with it, instead of leaking the host's own.
with Camoufox(headless=True, geoip=True, proxy=PROXY, os="windows") as browser:
    page = browser.new_page()
    page.goto("https://www.sparkproxy.io/", wait_until="domcontentloaded")
    print(page.evaluate("navigator.userAgent"))

Camoufox wraps Playwright, so launch options including the proxy dictionary follow Playwright's shape. Being a library rather than an application, it has no dashboard, no team roles and no cloud profile sync, so it replaces the automation half of Indigo and none of the account-management half. We compare it against stock Playwright Firefox in Camoufox vs Playwright Firefox.

Here is the check the axis implies, turned into something you can run against any browser on this list. It compares the engine version a vendor claims against the one the binary actually reports:

import re
from camoufox.sync_api import Camoufox

CLAIMED_MAJOR = 156  # the major named in the project's own release notes

with Camoufox(headless=True) as browser:
    ua = browser.new_page().evaluate("navigator.userAgent")

match = re.search(r"Firefox/(\d+)", ua)
running = int(match.group(1)) if match else None

print("user agent:", ua)
print("claimed:", CLAIMED_MAJOR, "| running:", running,
      "| verdict:", "match" if running == CLAIMED_MAJOR else "DRIFT")

A browser whose reported major trails the real release channel by several versions is wearing a rarer fingerprint than a stock install, which is the opposite of the goal.

AdsPower passes the test on both engines, which matters if you picked Indigo for Mimic and Stealthfox. Its release pages at adspower.com/release/ are dated: v8.7.23 on 2026/09/30, and a kernel entry on 2026/09/23 recording Chrome 153 along with Firefox 153 support, including on Linux. A vendor dating its Firefox engine within the last three weeks is a direct replacement for one whose Firefox engine is pinned at 146.

The automation ceiling is where AdsPower separates hardest from Indigo, and it is a like-for-like number. Indigo's API is capped at RPM 50 on PRO 10 and RPM 100 from PRO 50 upward. AdsPower publishes Local API limits of 300 requests per minute on Professional, 900 on Business and 1,500 on Enterprise. Three hundred against fifty is a different class of throughput for anyone driving profiles from a script.

There is a free-forever tier of 2 profiles, a stated 7-day trial of all features, and billing offered in USD, BRL, PLN and VND with quarterly and annual discounts of 15% and 40%. I am not quoting AdsPower's tier prices: the pricing table renders its amounts client-side and served me -- placeholders, the same class of problem I hit on Indigo, and I would rather leave a figure out than publish one I could not read. The antidetect browser pricing comparison carries the worked numbers across this category.

GoLogin publishes the busiest release feed of the commercial tools here. At gologin.com/release-notes/, App 4.22.2 Saturn is dated 6 October 2026, with 4.18.3 on 28 September, an Android app build 2.18.151 the same day, 4.14.1 on 21 September and 4.12.4 on 18 September. Five dated builds inside three weeks.

It passes points 1, 2 and 4 of the test and fails point 3: the entries name application versions, not the engine build underneath. You learn that something shipped on a given day without learning which Chromium you are now running. For the version-drift question, that puts GoLogin above Indigo and below Octo.

Pricing is USD, annual rates shown with a 50% discount: Free at $0, Professional 10 at $4.50 a month, Professional 25 at $9.50, Professional 50 at $14.50, Professional 100 at $19.50, Business 300 at $49.50, Business 500 at $69.50, Enterprise at $89.50 and Custom at $139.50 for 2,000-plus profiles. A 7-day trial covers the paid plans. Cloud Browser via web arrives at Professional 50 and above, REST API and SDKs at Professional 100 and above, and a Cloud Android add-on carries monthly minute allowances from 30 to 120 depending on tier. That Android option is the nearest match to Indigo's mobile profile emulation, though it is metered in minutes rather than bundled.

Compare carefully at the low end. Professional 100 at $19.50 a month annually covers 100 profiles; Indigo's PRO 100 covers the same count at €51.35 annually. The REST API is included at that GoLogin tier, where Indigo's equivalent allows RPM 100 and 2 team accounts.

Undetectable's changelog is the best-written one in this comparison, and it is the only commercial entry here that reads like release notes an engineer produced. v2.51.0, 15 September 2026, states: "Chromium core has been updated to version 153; English uses the en-US/en-GB locale instead of en; Added an option to disable DPR spoofing in the profile's Window Size settings; Improved Widevine DRM operation in the browser; Fixed the operation of Start page". Behind it, v2.50.1 and v2.50.0 on 1 September and v2.49.x on 4 August, with the Chromium series traceable back through 152, 151 and 150 and the archive reaching Chromium 107.

Naming the locale change and the DPR toggle is the kind of detail that tells you whether a profile you built last month still behaves the same way. At 24 days, its newest entry is the oldest of my five picks, which is why it sits last; the trade is depth per entry rather than frequency.

The structural difference from Indigo is profile storage. Undetectable separates cloud profiles from local ones and makes local profiles unlimited on any paid plan, describing it directly: "A local profile is stored directly on your device and is unlimited on any paid plan. Cloud profiles are stored on our servers or your own private servers." Pricing in USD is Free at $0 with 5 to 45 cloud profiles, Base at $34 a month for 50 cloud profiles and one user, Professional at $69 for 100 cloud profiles and two users, and Custom at $139 reaching 10,200 cloud profiles and up to 100 users, with a 30% annual discount and a Local API from Base upward.

For anyone whose Indigo complaint is the profile ceiling rather than the price, unlimited local profiles on a $34 plan is the specific answer. The cloud-profile count is what you are buying.

An honest axis has to be able to return "no change needed", and here it does.

Nothing I found suggests indigobrowser.com is abandoned. The homepage advertises Mimic core 148, which is nine majors ahead of the newest core its own changelog records, so the engines are plainly being updated whether or not anyone writes it down. The product is shipping and the documentation is lagging, which is an ordinary failure of a small team's attention rather than a sign of decay. A seized or dead vendor looks nothing like this: it looks like law-enforcement nameservers or a dead socket, and Indigo has neither.

Keep the gap in proportion, though. Octo's engine changelog put Chromium at 155 on 8 October 2026, so Mimic at 148 is roughly seven majors behind the current Chromium line, and Stealthfox at 146 is ten behind Camoufox's Firefox 156. Those are real distances, not rounding. They are also distances you can measure yourself in a few seconds with the drift script above, which is the point of preferring a checkable test to a vendor's adjective.

Stay if you are a solo operator on PRO 10. At €9 a month, or €5.85 on annual, with two engines, local and cloud storage, Android profiles and an API, the entry tier is priced below most of this list, and the documentation gap costs you very little when you are the only person who needs to know what changed. Stay if your team already works in Russian and support over Telegram suits you; replacing a responsive support channel with a slower one in a second language is a real loss that no changelog offsets.

Move if any of these is true. You bill clients and need a dated record of engine changes. Your workflow depends on the Firefox engine, where Stealthfox at core 146 is the binding constraint. You are automating past RPM 100. You need more than two team accounts below the Business tier, since PRO 10 and PRO 50 both carry zero. Or you are about to migrate between Indigo generations anyway, in which case you are paying the switching cost regardless and may as well price the alternatives while the profiles are in motion.

Because the Indigo 6 to Indigo X path currently routes through support, anyone moving is doing manual work either way. Two things make that work survivable, and neither is specific to a destination.

The asset that carries is the session, not the profile file. Cookies, local storage and the proxy-to-account binding are what keep a logged-in account logged in; the fingerprint is regenerated at the far end. Indigo X's own documented features include cookie import and export with presets and selective profile import and export, so the export side exists even while the generation-to-generation tool does not. Export in batches small enough to verify, and keep the batch that is in flight logged out of nothing.

The part that actually burns accounts is the IP. If a profile has reached a platform from one city for six months and arrives tomorrow from another country because the new browser bundled its own proxy pool, the fingerprint continuity you worked to preserve is beside the point. Keep the exit IP stable across the cutover and change one variable at a time. This is the strongest practical argument for not using a browser vendor's bundled proxies as your primary pool: a bundled pool cannot follow you to the next browser, and Indigo's own allocation is metered at 1GB to 10GB by tier, which is a small budget for sustained work.

Every tool above either bundles a metered proxy allowance or expects you to bring your own. A pool you own is the one component on this page that survives every migration, including a migration back.

SparkProxy residential plans start from $75 a month and are sold as packs rather than per gigabyte, with unlimited bandwidth included, so the billing unit is the plan and its concurrency rather than traffic consumed. That removes the metering problem that makes a bundled 1GB allowance awkward: the pool covers 1M+ premium IPs across 80+ countries, with random rotation and 5-minute auto-rotation, HTTP/HTTPS/SOCKS5, IP whitelist or user:pass authentication, and 1 Gbps port speed. There is a 24-hour free trial with no credit card, and term discounts of 5%, 10% and 15% at three, six and twelve months. For the fingerprint-versus-IP division of labour, antidetect browsers versus proxies sets out which layer solves which failure.

The verification in this post is also something you can automate, and it is worth automating if you are auditing several vendors on a schedule. SparkProxy's Scraping API will fetch a changelog page for you. Note the envelope rule, because it trips people up: json_response=true is the only way to get the metadata wrapper, and the body it returns is base64, so it must be decoded before you match anything against it. Setting render_js=false makes this a plain fetch at 1 credit instead of 5:

import base64
import re
import sys

import requests

API = "https://scrape.sparkproxy.io/api/v1"
KEY = "YOUR_SPARKPROXY_API_KEY"
DATE = re.compile(r"\b\d{1,2}[./-]\d{1,2}[./-]20\d{2}\b|\b20\d{2}-\d{2}-\d{2}\b")


def newest_date(page_url):
    resp = requests.post(
        API,
        headers={"X-API-Key": KEY, "Content-Type": "application/json"},
        json={"url": page_url, "render_js": False, "json_response": True},
        timeout=120,
    )
    resp.raise_for_status()
    env = resp.json()
    # The envelope's body is base64. Decode before any marker matching.
    html = base64.b64decode(env["body"]).decode("utf-8", "replace")
    return env, DATE.findall(html)


for url in sys.argv[1:]:
    envelope, dates = newest_date(url)
    print(
        url,
        "status=", envelope["status_code"],
        "ms=", envelope["duration_ms"],
        "credits=", envelope["credits_used"],
        "dates=", dates[:5],
    )

The other half of my research needed a rendered page, because Indigo's prices are written by JavaScript. extract_rules replaces the response with an extracted object, so it is never combined with json_response, and render_js has to stay on for the selectors to find anything:

import requests

API = "https://scrape.sparkproxy.io/api/v1"
KEY = "YOUR_SPARKPROXY_API_KEY"

payload = {
    "url": "https://vendor.example/pricing",
    "render_js": True,            # required for client-rendered prices; 5 credits
    "wait_for": "#price-monthly",  # a selector that only exists after hydration
    "proxy_type": "premium",
    "extract_rules": {
        "monthly": "#price-monthly",
        "annual": "#price-annual",
        "tiers": {"selector": ".plan .tier-name", "type": "list"},
    },
}

resp = requests.post(
    API,
    headers={"X-API-Key": KEY, "Content-Type": "application/json"},
    json=payload,
    timeout=180,
)
resp.raise_for_status()
print(resp.json()["extracted"])

Both run inside the 1,000 free credits a new key carries, which is enough to audit this entire category several times over. One practical note from doing it by hand: when a pricing page refuses to render, the prices are often sitting in plain text inside the site's own JavaScript bundle, which is how the Indigo table in this post was recovered.
