Scraping API PricesScrape.do vs ZenRows
The basic-request plan boundaries between two credit-metered scraping APIs.

The difference
Both paths, one ruler
Scrape.do
Successes you want
100,000 pages
Your stated workload. Every vendor on this site is priced against this same number.
- × 1
Attempts you are billed for
100,000 requests
Scrape.do does not bill failed fetches, so failures cost nothing here.
- × 5
What the meter counts
500,000 credits
One attempt is not one billed unit here: this workload multiplies by 5 before any money is involved.
- =
Cash per month
$99.00 /mo
Pro. Cheapest of every eligible purchase option, not the first plan that fits.
Bars share one linear scale across the 3 counted stages, so a multiplier shows as length. Units differ by stage and are labelled. Cash is not on that scale.

Startup. Cheapest of every eligible purchase option, not the first plan that fits.
Bars share one linear scale across the 3 counted stages, so a multiplier shows as length. Units differ by stage and are labelled. Cash is not on that scale.
Both ladders share one linear scale, topping out at 500,000 counted units, so a longer bar means more billed work rather than a different drawing.
These figures are for one stated workload: 100,000 JavaScript-rendered pages a month at a 95% success rate. The comparison below names where the answer changes.
The boundary
For successful basic datacenter requests, Scrape.do is cheaper through 3.5 million requests a month. ZenRows becomes cheaper from 3,500,001 through 6.2 million, then Scrape.do becomes cheaper again from 6,200,001 through its final published self-serve allowance of 10 million requests. The reversals come from plan steps: Scrape.do’s $249 Business plan covers 3.5 million credits, then its next plan costs $699, while ZenRows holds at $499.99 through 6.2 million basic results before moving to $999.99.

The low-volume result is also explicit. Scrape.do’s $29 Hobby plan and $99 Pro plan remain below the ZenRows plans that cover the same basic-request bands, so there is no hidden early crossover before 3.5 million. This boundary excludes free-trial credit because Scrape.do’s reviewed public text does not state a renewal period and ZenRows describes its free amount as a one-time trial.

Billing models side by side
Scrape.do sells monthly credits. A basic datacenter request consumes one credit, JavaScript consumes five, residential or mobile routing consumes ten, Google consumes ten, and AI extraction consumes twenty-five under the reviewed request-cost table. The published modes are replacement bundles rather than amounts that should automatically be added. Requests stop when a plan’s credits are exhausted unless the buyer changes plan or purchases more credits, and no universal public top-up rate is provided.

ZenRows also sells monthly balance through replacement request classes. A basic request consumes one credit, JavaScript five, premium proxy ten, and protected access twenty-five. Failed requests and internal retries are free, while HTTP 404 and 410 count as successful and are billed. Unused monthly balance does not roll over. ZenRows additionally uses a separate browser-time and bandwidth formula for Scraping Browser, so an interactive session is not priced by the basic-result allowance used here. (ZenRows pricing documentation, retrieved 2026-07-26)
Scrape.do bills HTTP 2xx, 400, 404, and 410 responses, while other failed or blocked responses are not charged. It also documents that per-domain defaults can select a different request cost than the caller expected, with the observed cost returned in a response header. Because the two vendors define billable responses differently, this comparison does not insert any success percentage or imply a reliability difference.

What each does that the other does not
Scrape.do is the only member of this pair whose reviewed product exposes ready-made APIs for named targets such as Google, Amazon, YouTube, Maps, Shopping, Flights, Hotels, News, Trends, and ChatGPT, with target-specific request costs. ZenRows is the only member whose reviewed pricing combines the request API with an interactive Scraping Browser billed by time and bandwidth and an explicit protected-result class in the same commercial system. A buyer comparing parsed target JSON with browser control is not comparing the same output, even if both products can reach the site.

Who should pick which
Pick Scrape.do through 3.5 million basic requests and again above 6.2 million through 10 million when its plan step is lower, especially when a ready-made target API removes parser work. Pick ZenRows inside the 3.5-million-to-6.2-million window or when its protected request class and Scraping Browser are the required products. The JavaScript multipliers happen to match at five credits in the reviewed tables, but residential, protected, AI, and target-specific jobs still need their own capacity calculation.

The unverified edge is preflight classification. Scrape.do does not publish a complete live table of every domain default, while ZenRows’ highest public plan figures disagree across first-party pages. Confirm the actual response-cost header or account debit on representative domains before committing to either high-volume band.
