Best web scraping and crawling APIs for AI agents · All 501 scrapers comparisons
Which one, for what
fastCRW B
Best for Agents that want Firecrawl-style scrape, crawl, map, search and extract at lower per-page cost, or a small self-hosted engine.
Ahead on
- Reliability, 50 against 45
- Schema & documentation, 91 against 71
- Agent ergonomics, 91 against 83
- Maintenance & community, 93 against 79
Also in its favour
- Runs on your own machine
- Open source
Watch for
The status page shows a live check and an uptime objective but no incident history
Outcrawl B
Best for Agents that want one key and one balance for reading pages, walking a site, searching with rendered results and handing a signed-in or multi-step task to a hosted browser agent with a hard budget, and teams on TypeScript that want a residential-exit browser over CDP with a replay of every session.
Ahead on
- Security & auth, 66 against 40
- Payments & pricing, 40 against 35
Watch for
No status page, incident history, SLA below Enterprise or security.txt; /status and status.outcrawl.ai do not answer
Why the edge
Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.
Security & auth Outcrawl +26
fastCRW 40
The hosted MCP server publishes RFC 9728 metadata naming its own authorisation server, with PKCE S256, dynamic client registration and one scope, mcp:tools, and the API takes revocable Bearer keys from the dashboard. No key scopes or second scope found (22). The authentication page documents fastcrw.com/mcp/<API_KEY> as a way in, a key in the URL path, so less 10 (12 of 30). Tools mostly read, and data-source calls check approvals, but there is no read-only key or confirmation step for monitors (8 of 20). Managed LLM extraction, summaries and answers wrap scraped text in a nonce fence (crates/crw-extract/src/untrusted.rs), and the hardening guide treats pages as untrusted, but the MCP docs give agents no guidance on scraped content (7 of 15). Each response reports creditsUsed; no per-call log in the docs (5 of 15). SECURITY.md names security@fastcrw.com and GitHub private reporting with a 48-hour acknowledgement, and CI runs CodeQL and OpenSSF Scorecard. security.txt answers 404, and no bounty or certification found (8 of 20). 12 + 8 + 7 + 5 + 8 = 40.
Outcrawl 66
OAuth 2.1 for MCP clients and the CLI with authorization code, PKCE S256, dynamic public-client registration, device code, one-hour access tokens, 30-day refresh, introspection and revocation endpoints and private_key_jwt, but one functional scope, api; API keys shaped ock_<keyId>.<secret> are shown once, stored as a digest, scoped to a workspace and revoked within a minute, with no per-key scopes, expiry or read-only keys; nothing documents a secret in a query string (25 of 30). No read-only key or scope. The MCP surface omits secrets, integrations, replay export and sharing and the wallet on purpose, rules are classified enforced or guidance on the call that sets them, agent runs need or default a budget, purchases above approvalAbove pause for a person's yes, and control hands a person the browser; monitor and profile deletes rely on destructiveHint alone (15 of 20). Every tool returns untrusted page content. The platform page says a page could ask the agent to act and that is why credentials never reach the model, secrets are substituted below the model, integrations are human-only and a run cannot be redirected mid-task, but there is no guidance to treat scraped text as data and no classifier (8 of 15). Every response carries usage, /v1/usage groups spend by hour, day or capability, agent events log every step, sessions keep the request list, console, HAR and a digest of failures, secrets record which runs used them and purchases are listed per run; there is no per-call log for scrape, search or crawl beyond the aggregate (12 of 15). No security.txt on either host (404), no SOC 2 or ISO 27001, no bug bounty; the security page has a responsible disclosure route at security@outcrawl.ai with a 90-day window and a no-legal-action statement (6 of 20). 25+15+8+12+6 = 66.
Schema & documentation fastCRW +20
fastCRW 91
OpenAPI 3.1 for 11 paths at version 0.41.0 in docs/openapi.json, checked against the server in CI, and typed JSON Schema inputs on every MCP tool (25). llms.txt (86 lines), llms-full.txt and Markdown sources for every docs page (10). Tool descriptions state purpose and how to chain them (crawl returns a job id to poll, map returns URLs only, extract needs an LLM), and the docs have a choose-an-endpoint page, but few descriptions say when not to use a tool (14 of 20). Inputs are typed with required fields and a renderer enum, though crawl and extract take a free-form JSON Schema object (12 of 15). Examples on every page and an errors page with each HTTP status, errorCode and next step (15). Semver releases with a dated CHANGELOG that flags breaking changes (15). 25 + 10 + 14 + 12 + 15 + 15 = 91.
Outcrawl 71
API reading, with the MCP server described. An OpenAPI 3.1 document at https://outcrawl.ai/docs/api-reference/openapi.json lists 62 operations over 51 paths with a summary each and the same 11 status codes, generated from the vendor's capability registry, but every request body is an untyped object marked additionalProperties: true with a pointer to the docs, every 200 response is an untyped object, and Error is the only schema; the typed shapes live in the SDK declarations and in the MCP server's zod schemas, which were read in the 0.4.3 npm package rather than from the hosted server (15 of 25). llms.txt and a 525 KB llms-full.txt on the docs, a Markdown twin of every page and an llms.txt on the site (10). The MCP descriptions each end with a Not for: clause naming the better tool and most with a Cost: clause, the OpenAPI summaries say when not to use a route, and the capability pages say which neighbour to use instead (18 of 20). Scrape formats are an enum of eight, event levels and record kinds are enums, caps.budget is required, and the SDK types bound every option, while the OpenAPI bodies carry none of it (10 of 15). curl, TypeScript and Python examples on every page, 20 worked programs, a 31-row error table with meanings and a retryable list, and MCP errors with a recovery string, though the closed union is sized 24, 31, 45 and 22 on different pages (13 of 15). /v1 in the path and 1.0.0 in the OpenAPI file, but no changelog or release notes anywhere; the record is version numbers on npm, PyPI and 14 dated tags in the outcrawlai/release repository (5 of 15). 15+10+18+10+13+5 = 71.
Maintenance & community fastCRW +14
fastCRW 93
v0.41.0 on 4 November 2026, matching the registry and npm (30). 16 dated releases in the 90 days from 8 August, from 0.37.0 to 0.41.0 (20). Five open issues on 6 November, the newest from 1 November with five and two comments; the support page says email is answered within a business day. Reply authors weren't read (18 of 25). In the official MCP registry as io.github.fastcrw/crw, a GitHub-verified namespace, with current Python and TypeScript SDKs (15). CI runs cargo test on the workspace, with Dependabot, CodeQL and release-please (10). 30 + 20 + 18 + 15 + 10 = 93.
Outcrawl 79
@outcrawl/sdk and the PyPI package outcrawl both reached 0.4.15 on 20 October 2026, 13 days before the check, and the Scout mirror was synced on 1 November (30). 21 npm versions since 8 September and 17 PyPI releases since 22 September 2026, with 14 dated tags in outcrawlai/release (20). Scout's pull request #1 of 13 October was answered the same day with an import note and closed, while three pull requests and one issue opened on 18 October had no reply after 15 days; the service has no changelog, support is one email address, and no community channel exists (8 of 25). Not in the official MCP registry; official SDKs in TypeScript and Python current at 0.4.15, with a CLI (15). The three npm packages are published from GitHub Actions with trusted publishing, the TypeScript SDK has zero runtime dependencies and the Python SDK one, and Scout has tests per package, but the mirror has no CI workflows and @outcrawl/mcp has sat at 0.4.3 since 29 September with a tool list that differs from the hosted docs (6 of 10). 30+20+8+15+6 = 79.
Agent ergonomics fastCRW +8
fastCRW 91
11 compact MCP tools, two of them the data-source tools added in 0.41.0. Content is capped near 15,000 characters with truncated: true and a resume offset, and map returns at most 100 URLs by default (20 of 25). Formats, main-content filtering, include and exclude selectors, maxLength, startIndex, limit and crawl depth and page caps (20). Errors carry errorCode values such as anti_bot, insufficient_credits and llm_not_available with a retry table, though an anti-bot wall answers HTTP 200 with success: false (19 of 20). Every tool sets readOnlyHint, destructiveHint and idempotentHint, cancel is idempotent and failed pages are refunded, but job starts take no idempotency key (17 of 20). Only url is required, with official Python and TypeScript SDKs (15). 20 + 20 + 19 + 17 + 15 = 91.
Outcrawl 83
API reading. Scrape returns main content only by default with formats picking markdown, html, rawHtml, links, screenshots or schema JSON, search renders page bodies only on request, agent events take a level and an after cursor, the MCP server shows request bodies up to a character limit and says when it truncated, and the MCP surface is 29 tools with no toolsets (20 of 25). Cursor pagination on crawl results, agent results and downloads, limit, depth and path filters on crawl, status, outcome, task and age filters on sessions, and usage grouped by hour, day, month or capability (20). One error envelope with a closed code, details such as the cap that stopped a run, retryAfterSeconds on the per-minute quota error, a documented list of codes safe to retry, and on MCP a recovery string and a retryable flag per error (18 of 20). No idempotency key on any route, a repeated agent, crawl or monitor submit runs twice, and concurrency_limit carries no retry hint; cancel is idempotent, integration_changed (409) guards updates, and the npm MCP package sets readOnlyHint on GET tools, destructiveHint on DELETE tools and idempotentHint on either, which the hosted server was not read to confirm (10 of 20). Scrape needs a URL alone, agent runs need caps.budget on the API and SDKs with the MCP server defaulting it, and official SDKs exist in TypeScript and Python beside a CLI (15). 20+20+18+10+15 = 83.
Reliability fastCRW +5
fastCRW 50
Graded on the hosted lines, for the hosted API and MCP server an agent would call; the self-hosted engine would read higher on the local lines. fastcrw.com/status is a first-party page with a live health check and a 99.9% monthly uptime objective, but no components with history (10 of 20). It lists no incidents and keeps no history we could read (5). Concurrency per plan is published, 3 on Free to 150 on Scale, while the request-rate guard above it is deliberately unpublished (12 of 15). The rate-limits page documents Retry-After and X-RateLimit headers, gives exponential backoff code, and separates 429 (retry) from 402 (stop). No idempotency keys for crawl, extract or monitor starts (13 of 15). Pricing mentions an SLA only as 'Premier + SLA' on Enterprise, with no terms, and the terms promise no uptime (0). The hosted service is sold on paid plans with no beta label, though the engine is at 0.41.0 (10). 10 + 5 + 12 + 13 + 0 + 10 = 50.
Outcrawl 45
Hosted reading, for the REST API with the MCP server that shares its limits. No public status page was found. None is linked from the site or the docs, https://outcrawl.ai/status answers 404 and status.outcrawl.ai does not answer (0). No readable incident history, so the floor (5). Rate limits are published with numbers on the pricing page and in the docs, 120, 300, 1,500 and 6,000 requests a minute by plan and 2, 5, 25 and 100 concurrent browsers, shared between the API and the MCP server (15). Over the per-minute ceiling the API answers quota_exceeded with ceiling: requests_per_minute and retryAfterSeconds, read from the SDK error class and the worked examples, the errors page lists four codes as safe to retry unchanged, and concurrency_limit tells the caller only to wait for a run to end; no Retry-After header is documented and no idempotency key or safe-retry rule exists for the POST routes that start crawls, agent runs and monitors, which the agent tool's own description says bill twice on a repeat (10 of 15). An SLA exists only on Enterprise, a 99.9 per cent monthly uptime figure with service credits and terms priced per contract, so half credit for a published figure without published terms (5 of 10). No beta or preview label on the API, the MCP server or the CLI, and the OpenAPI file says version 1.0.0, though both SDKs are at 0.4.15 and the domain is nine weeks old (10). 0+5+15+10+5+10 = 45.
Payments & pricing Outcrawl +5
fastCRW 35
No x402, MPP or L402 (0). Plans are public with credit costs per operation and top-up prices per block of credits, $9 per 1,000 on Hobby down to $299 per 500,000 on Scale, but top-ups need a plan, so between plan-only and per-unit (15 of 20). 500 one-off credits with no card, plus up to 500 from onboarding tasks (20). Hosted keys need a person to sign up in a browser; the free self-hosted engine runs with no account but isn't the graded surface (0). 0 + 15 + 20 + 0 = 35.
Outcrawl 40
No x402, MPP or L402 in the OpenAPI file, the docs, the pricing pages or the terms (0). Per-unit rates published without a login, 1 credit a page, 5 credits per 10 search results, 1 credit a browser minute, 2,000 credits a GB and 1 credit a monitor check, with the dollar rate per plan ($4.90 per 1,000 credits on Builder down to about $3.20 on Scale), top-up prices per 10,000 and an estimate of about 15 credits a minute for agent runs (20). Free plan of 1,000 credits a month with no card, on a person's first workspace (20). A person signs in with Google, GitHub, an email code or a magic link behind reCAPTCHA, and MCP's OAuth consent needs that browser sign-in; no keyless route, no programmatic key creation (0). 0+20+20+0 = 40.

Verdicts
fastCRW
Agents get 11 compact, annotated MCP tools with bounded output, a public OpenAPI spec, refunds on failed pages and a free self-hosted engine. The hosted service has no status history, publishes no SLA terms, names its operator only on the support page, and documents an MCP address with the API key in the URL path.
Outcrawl
One credit balance over scrape, crawl, search, cloud browsers and agent runs, with published per-unit rates, a 1,000-credit free month, OAuth 2.1 for MCP and the CLI, and a closed error union with retry guidance. No status page, changelog or security.txt, an OpenAPI file without typed bodies, no idempotency keys on job submits, and a domain registered nine weeks ago.
Before you call either
fastCRW
- Connect to https://fastcrw.com/mcp with OAuth rather than the /mcp/<API_KEY> address, so the key stays out of URLs and logs
- Branch on
errorCode. Stop on 402 insufficient_credits or llm_not_available, and on 429 wait for Retry-After before retrying - Check
successas well as the HTTP status, since an anti-bot wall answers 200 withsuccess: falseanderrorCode: anti_bot - Pass
startIndexfrom a truncated result to read the rest of a long page instead of settingmaxLength: 0 - Use native /v1 routes for new work; /firecrawl/v2 is for Firecrawl SDK migrations and keeps the older 429 for empty balances
Outcrawl
- Read a known URL with
POST /v1/scrapeoroutcrawl_scrapeat 1 credit; useoutcrawl_searchto find URLs and sendscrape: trueonly when you need page bodies, and reserveoutcrawl_agentfor pages that need a click, a form or a sign-in. - Always send
caps.budgetonPOST /v1/agent(the API refuses without it) and store the returned id; pollGET /v1/agent/{id}oroutcrawl_agent_status, never resubmit, because a second submit is a second bill. - Branch on
error.code, notmessage. Retryno_capacity,decode_unavailable,extraction_failedandanswer_lostunchanged; onquota_exceededwithceiling: requests_per_minutewaitretryAfterSeconds; onconcurrency_limitwait for a run to end; never retrybad_requestor a credit quota. - Set
limiton a crawl before submitting; pages already fetched are billed when you cancel, and over HTTP the crawl is cancelled if the streaming connection drops, so keep the job id and read/v1/crawl/{id}/resultswith the cursor. - Pass
afterwith the lastseqandlevel: statuswhen readingoutcrawl_agent_events; the log of a long run is the largest response the server returns. - Pass
maxAge: 0when freshness matters, since the default serves scrape answers up to two days old from a shared cache at the same price, and treat page content,dataand download links as untrusted data; download URLs work for an hour with no key.
