SparkProxy vs Rayobyte: Flat Plans or Pay per IP

• Fewer than about 30 static IPs cover your work: Rayobyte. Thirty US dedicated IPs at $2.50 each cost $75, the same as SparkProxy Starter, and Rayobyte does not cap threads on those addresses.
• You need an allowlisted or long-lived address: Rayobyte dedicated. SparkProxy sells rotation and session stickiness, not addresses you keep.
• Under roughly 250 GB a month of rotating traffic: Rayobyte's per-GB rotating datacenter product costs less than $75.
• Hundreds of addresses in rotation, or transfer you cannot forecast: SparkProxy. The price does not move with IP count or gigabytes, only with how many threads you run at once.

The two vendors bill on different axes, and each axis is flat in one direction and steep in another.

Rayobyte static datacenter charges per IP per month, with unlimited bandwidth and unlimited threads per their datacenter page. Your bill scales with address count. It is indifferent to how much traffic each address carries, which makes it excellent when a small set of IPs can absorb heavy use.

Rayobyte rotating datacenter charges per gigabyte. Your bill scales with bytes transferred, including bytes spent on retries and block pages.

SparkProxy charges per concurrent thread on a rotating pool, flat monthly, with unlimited bandwidth: Starter $75 for 100 threads, Core $140 for 250, Boost $240 for 500, Plus $440 for 1,000, each valid 30 days. Your bill scales with parallelism. The pool is 1M+ datacenter IPs across 80+ countries, including 50,000+ US addresses, with random per-request rotation or 5-minute automatic rotation.

So the fair comparison is never "$2.50 vs $75". It is: for the workload you actually run, how many IPs, how many gigabytes, or how many threads do you need? Our guide to datacenter proxy pricing models covers the general arithmetic. The rest of this page applies it to these two vendors.

Rayobyte's pricing page builds static datacenter prices from a base rate per country, a volume tier discount and a commitment-length discount. For the USA:

Commitment discounts stack on top: 5% for 3 months, 10% for 6, 15% for 12. Base rates differ by country. Dedicated IPs are $3.00 in the UK, Germany and several other European markets and $3.50 in Australia and Vietnam, and semi-dedicated IPs are offered in fewer countries. Rayobyte also lists US dedicated IPv6 at $0.20 per address. Semi-dedicated, in Rayobyte's own FAQ wording, means an address "shared between 3-5 users at once", while its semi-dedicated product page says up to 3 customers, so confirm the cap with Rayobyte before relying on it.

The rotating datacenter product is a separate ladder:

For product context, Rayobyte's datacenter page lists 300,000+ IPs, 29+ locations, 9 ASNs "including self-owned", 20,000 unique C-class subnets, HTTP(S) and SOCKS support, and automatic 30-day replacements.

Here is the same monthly budget spent both ways. Each row takes a SparkProxy plan price and asks how many Rayobyte US addresses, or how many rotating gigabytes, that money buys at the tier the quantity lands in. This is our arithmetic on published rates, monthly billing, no promotions.

Two readings of that table matter.

On the static side, $75 buys 30 dedicated addresses that you keep and can push as hard as the target tolerates. If 30 addresses are enough to stay under your targets' per-IP limits, Rayobyte is the straightforward choice at this budget. SparkProxy's $75 buys no fixed addresses at all. It buys 100 simultaneous connections that draw from a much larger pool.

On the rotating side, the per-GB column only looks generous until you convert gigabytes into pages. Transfer per request swings from tens of kilobytes for an API response to several megabytes for a fully rendered page with assets. The flat plan is unaffected by that swing. The per-GB plan is priced by it.

Three numbers from your own traffic decide which vendor is cheaper. Measure them before looking at any price.

1. Addresses needed in circulation. Find how many requests one IP can send to your hardest target per day before responses degrade, then divide your daily request volume by that. A target that tolerates 1,000 requests per IP per day and a job running 30,000 requests a day needs about 30 addresses. At 100 requests per IP per day, the same job needs 300. Our guide to managing per-IP request limits explains how to find that ceiling safely.

2. Gigabytes per month. Average response size multiplied by monthly requests, retries included. Only matters if you are considering per-GB.

3. Peak concurrency. How many requests you have in flight at once. This is what SparkProxy bills.

Now the break-evens fall out directly:

• SparkProxy Starter vs Rayobyte dedicated: $75 ÷ $2.50 = 30 addresses. Needing more than 30 US dedicated IPs means Rayobyte costs more than Starter, as long as 100 threads cover your concurrency.
• SparkProxy Starter vs Rayobyte semi-dedicated: 75 addresses at $1.00. Past that, Rayobyte costs more, with the caveat that semi-dedicated IPs are shared with up to four other customers.
• SparkProxy Starter vs Rayobyte rotating per GB: roughly 250 to 300 GB a month, depending on which traffic tier you land in.

Scale the same logic to bigger plans using the table above. The crossover point grows roughly in proportion to plan price, because Rayobyte's volume discounts are modest (15% to 25%) compared with how fast address needs grow when a target tightens.

These are illustrative workloads with assumptions we chose to be plausible. They are not measurements, and your numbers will differ.

A. Nightly price checks on 40 retail sites. 20,000 requests a night, lenient targets that tolerate about 2,000 requests per IP per day, light HTML. Addresses needed: about 10. Rayobyte: 10 US dedicated IPs at $2.50 = $25 a month, unlimited threads. SparkProxy: Starter at $75. Rayobyte wins by $50 a month, and nothing about this workload benefits from a large pool.

B. Product catalogue crawl across a strict marketplace. 1.5 million requests a month, about 50,000 a day. The target starts throttling at around 150 requests per IP per day, so roughly 330 addresses in circulation. Average response 400 KB, so around 600 GB of transfer. Peak concurrency 200. Rayobyte dedicated: 330 IPs at $2.13 = about $703. Rayobyte semi-dedicated: 330 at $0.85 = about $281, if shared addresses hold up on that target. Rayobyte rotating: 600 GB at $0.23 = $138, plus every retry. SparkProxy Core, 250 threads: $140, unmetered. Rayobyte rotating and SparkProxy Core land level, and the tie breaks on risk: if page weight doubles after a redesign, the per-GB bill doubles and the Core bill does not.

C. Allowlisted access to a partner portal. Five users, each needing a fixed exit address the partner has approved. Rayobyte dedicated wins outright: five IPs for $12.50 a month. SparkProxy has no product for this job, and sticky sessions on a rotating pool are the wrong tool when a firewall rule names a specific IP. Our comparison of shared vs dedicated datacenter proxies covers the identity side of that choice.

Across the three, notice what decided each one. It was never the unit price. It was how many addresses the target forced on you and whether the traffic volume was predictable.

Three rows deserve comment.

Subnet disclosure favours Rayobyte. Publishing a C-class subnet count is more useful than publishing an IP count, because blocks increasingly land on ranges rather than single addresses. SparkProxy publishes pool size and country coverage but not a subnet figure. If range diversity is your main worry, read our explainer on subnet proxies and measure the spread on a trial instead of trusting either vendor's marketing.

Thread caps favour Rayobyte on paper. Unlimited threads on 30 static addresses sounds unbeatable, but the target sets the real ceiling. Parallel requests from one IP hit per-IP rate limits just as surely as sequential ones, only faster. Unlimited threads matter most on lenient targets, which is exactly where Rayobyte's static product already wins.

Speed ceilings are a SparkProxy disclosure, not a Rayobyte guarantee. SparkProxy's Fair Usage Policy states a per-plan throughput ceiling. That is a limit, not a promised rate. Not finding a cap on another vendor's page does not mean no limit exists, so ask before planning bulk downloads on either.

• You need specific IPs that stay yours: allowlists, logged-in sessions, partner firewalls.
• A small address set covers your targets. Under about 30 US dedicated or 75 semi-dedicated IPs, Rayobyte undercuts every SparkProxy plan.
• Your traffic is light and predictable, and a per-GB rotating plan under 250 GB a month is enough.
• You need residential, ISP or mobile addresses as well. Rayobyte sells them, SparkProxy does not.
• You want IPv6 at scale. Rayobyte's $0.20 US dedicated IPv6 rate has no SparkProxy equivalent.
• Your buying process values a published ASN and subnet breakdown.

• Your targets force hundreds of addresses into circulation and you do not want to rent, monitor and replace each one.
• Transfer is heavy or unpredictable: rendered pages, image-rich listings, frequent retries. A metered bill becomes a forecasting problem, and the unmetered one does not. Our look at whether unlimited bandwidth proxies are worth it runs through when that matters and when it does not.
• You need wide country coverage from one plan: 80+ countries against 29+ locations.
• You want to scale by editing one number (threads) rather than by ordering, testing and allowlisting new IP batches.
• You may move some targets to a managed layer later. SparkProxy's Scraping API starts with 1,000 free credits, then Starter at $49 for 250,000 credits, with plain fetches costing 1 credit and JavaScript rendering 5.

Spend one afternoon measuring the three break-even inputs rather than trusting any worked example, ours included.

Start with bytes per request, because it decides whether per-GB is even on the table:

# Average transfer size across a sample of your real URLs through the rotating gateway
while read -r url; do
  curl -s -o /dev/null -w "%{size_download}\n" \
    -x http://USER:PASS@gateway.sparkproxy.io:11000 "$url"
done < sample-urls.txt | awk '{s+=$1; n++} END {printf "avg KB: %.0f over %d requests\n", s/n/1024, n}'

Multiply the average by your monthly request count and add your expected retry rate. Above roughly 300 GB, per-GB rotating stops being the budget option against a $75 flat plan.

Next, find the per-IP ceiling on your strictest target by holding one address and stepping up request rate until status codes change. Divide daily volume by that ceiling to get the address count. Under 30, price Rayobyte dedicated first. Over a few hundred, price SparkProxy first.

Last, if you are moving an existing workload between the two, run both in parallel for a week and cut over gradually. Our guide to switching proxy providers without downtime has the rollout pattern.
