ScrapFly earns its reputation on anti-bot bypass and excellent docs. WebScraping.AI offers the same core job — rendered pages through datacenter, residential, or stealth proxies plus AI extraction — with flatter, cheaper credit math and 7 official SDKs.

No tool is right for everyone. ScrapFly is a capable product, and these are the areas where it genuinely shines — worth weighing before you switch.
The most common reasons teams evaluate a switch.
Residential proxies cost 25 credits and JS adds 5 more on ScrapFly, so a protected, JS-rendered scrape burns 30 credits — the 200k-credit Discovery plan collapses to ~6,600 such requests, and users report bills quietly tripling. WebScraping.AI's same configuration costs 25 credits on a 250k-credit $29 plan, and residential without JS is 10 credits, not 25.
ScrapFly's anti-bot bypass consumes a variable number of credits depending on what the target requires, which makes hard-site budgets unpredictable. WebScraping.AI's stealth tier is a flat 50 credits per request — expensive targets are at least predictably expensive.
ScrapFly's Scrape Failed Protection stops applying once more than 30% of your traffic fails within an hour — exactly the scenario you're in when a target starts blocking you. WebScraping.AI simply never bills a failed request, with no fairness threshold.
Every ScrapFly plan is a monthly subscription — exhaust Discovery's 200k credits and you're done for the month unless you upgrade tiers. WebScraping.AI sells prepaid pay-as-you-go top-ups from $20 with no subscription at all, and on a plan they act as overflow, spent only once the monthly quota runs out. Plans are self-serve and adjustable at any time, and more of your credits survive contact with real-world targets thanks to the flatter multipliers.
Every request type has a fixed, published credit cost — no surprises, and you only pay for successful requests.
Plans from $29/mo (250k credits) · $99/mo (1M) · $249/mo (3M) · or pay-as-you-go from $20 (100k credits, no subscription, valid 12 months). Failed requests are always free. See full pricing.
Both products use credit multipliers — that's the market standard. The difference is where the multipliers sit. On ScrapFly, the moment a site needs residential IPs you're at 25 credits, and 30 with rendering. On WebScraping.AI, residential is 10 credits (25 with JS), and the whole table is published: 1 / 5 / 10 / 25 / 50, +5 for AI extraction.
Concretely, 100k JS-rendered residential requests cost 3M credits on ScrapFly's model (30 each) versus 2.5M on ours (25 each) — and each plan dollar buys more credits to begin with (250k at $29 vs 200k at $30). Every request that fails along the way costs you nothing, unconditionally.
ScrapFly's Extraction API is capable — prompts, schemas, and auto-extract models. WebScraping.AI adds the endpoint developers reach for first when prototyping: /ai/question. Ask "what's the price?" or "is this in stock?" about any URL and get the answer back as a string — no schema required. When you're ready for structure, /ai/fields returns typed JSON for the fields you name.
Both ship first-party MCP servers, so the choice isn't about AI-agent readiness — it's about how much credit math and schema ceremony sits between you and the data.

Is WebScraping.AI a good ScrapFly alternative?
For most scraping workloads, yes: the same datacenter/residential/stealth proxy tiers and JS rendering with flatter credit costs (residential at 10 credits vs 25), unconditionally free failed requests, AI question answering and field extraction, and 7 official SDKs. ScrapFly keeps the edge on its specialized ASP anti-bot bypass and screenshot tooling.
How do the credit models compare?
Both use multipliers. WebScraping.AI: 1 credit plain, 5 with JS, 10 residential (25 with JS), 50 stealth, +5 for AI — all fixed and published. ScrapFly: 1 credit plain, +5 for JS, 25 residential, and a dynamic credit cost when ASP engages. Entry plans are $29/mo for 250k credits here vs $30/mo for 200k there.
Does ScrapFly charge for failed requests?
Normally no — its Scrape Failed Protection covers failures with eligible status codes. But the protection is suspended when more than 30% of your traffic fails within an hour, which is precisely what a blocking event looks like. WebScraping.AI never bills failed requests, with no threshold or fine print.
Can I buy WebScraping.AI credits without a monthly subscription?
Yes. Pay-as-you-go top-ups start at $20 for 100,000 credits ($0.0002 per credit) with no subscription required — useful for occasional or seasonal workloads that don't justify a monthly plan. ScrapFly requires a monthly subscription to buy credits at all. If you do have a plan, PAYG credits are consumed only after that month's quota runs out, and they stay valid for 12 months, with each new top-up extending the entire balance another 12 months.
Does WebScraping.AI handle anti-bot systems like ScrapFly's ASP?
Hard targets route through rotating residential proxies (10–25 credits) or stealth proxies (50 credits) designed for protected-site scraping. ScrapFly's ASP is a strong specialized system and may win on the most aggressively protected sites; the difference is our cost is flat and known before you send the request.
Can I use WebScraping.AI with AI agents like ScrapFly's MCP?
Yes — both ship first-party MCP servers. WebScraping.AI's exposes question answering, field extraction, HTML/text retrieval, and CSS-selector tools to Claude, Cursor, and other MCP clients, with content sandboxing against prompt injection enabled by default on the hosted server.
