Firecrawl Alternative in 2026 — fastCRW (Self-Host, Compatibility Matrix)

Verdict

Firecrawl is a real benchmark for AI-agent web scraping. The case for fastCRW is not "Firecrawl is bad." The case is that fastCRW is a Rust-native, self-hostable alternative on the overlap surface — /scrape, /crawl, /map, /search — that collapses the Firecrawl Docker stack into a single binary, with anti-bot and JS-rendering escalation built into the open core.

The compatibility matrix below has the full row-level detail.

Who this page is for

Three readers:

• Already on Firecrawl, planning the migration — go straight to the endpoint mapping: every Firecrawl route and its fastCRW equivalent, so the move is a one-URL change.
• Already on Firecrawl, evaluating self-host alternatives — skip to Capability matrix.
• Looking for an affordable web scraping service instead of firecrawl — see the pricing math section.
• Searching firecrawl vs fastcrw directly — the head-to-head section is the short version.

Capability matrix

Full row-level diff lives in COMPATIBILITY-firecrawl.md. Headline rows:

Capability	Firecrawl Cloud	Firecrawl self-host (OSS)	fastCRW
/v1/scrape	✅	✅ (no Fire-engine)	✅
/v1/crawl	✅	✅	✅
/v1/map	✅	✅	✅
/v1/search	✅	⚠️ no Fire-engine	✅ own built-in search stack
/v1/extract (LLM extraction)	✅ standalone route, multi-URL	⚠️ requires LLM key	✅ multi-URL (/v1/extract, up to 50 URLs; 1 scrape credit per URL + metered managed-LLM cost)
Deep research	✅ /v1/deep-research	❌ Cloud-only	✅ Research API (/v1/search/research/papers), 61.0% recall vs Firecrawl's 53.3% on the public ArXivQA benchmark
Anti-bot / block bypass	✅ Fire-engine	❌ Cloud-only	✅ open-core (12-signal block detection, UA rotation, proxy rotation)
Browser fallback	✅ Playwright/Puppeteer	✅ manual config	✅ auto-escalation HTTP → LightPanda → Chrome (CDP) → proxied Chrome, optional Camoufox stealth renderer
MCP server	✅ firecrawl-mcp-server	✅	✅ built-in crw-mcp
Self-host shape	n/a	Docker Compose: API + workers + Postgres + Redis	Single Rust binary (~8 MB image)
Memory baseline (self-host)	n/a	~1-2 GB	Low idle footprint
Cold start (self-host)	n/a	~5-15s	Fast local cold start
License	proprietary	AGPL-3.0	AGPL-3.0

Migration notes:

• /v1/extract is matched, including multi-URL. It accepts a urls array (up to 50 URLs per request) and returns a results array, billed as 1 scrape credit per URL plus the metered managed-LLM cost. /v1/scrape with formats: ["json"] + jsonSchema is the single-page equivalent.
• Response field-name divergence on a few metadata keys and on error envelope wording. See the matrix for the exact diff.

Firecrawl to fastCRW endpoint mapping

Migrating is a base-URL change, not a rewrite — you change one URL and keep your code. This table maps every Firecrawl endpoint to its fastCRW equivalent so you can audit the move before you make it. (Endpoint surface verified 2026-05-11; verify the live route list within 48h before quoting.)

Firecrawl endpoint	fastCRW endpoint	Migration note
POST /v1/scrape	POST /v1/scrape	Same request shape. A few metadata keys and error-envelope wording diverge — see the capability matrix.
POST /v1/crawl	POST /v1/crawl	Same shape. Poll job status the same way.
GET /v1/crawl/{id}	GET /v1/crawl/{id}	Same job-status contract.
POST /v1/map	POST /v1/map	Same shape.
POST /v1/search	POST /v1/search	fastCRW search runs on its own built-in search stack; results parity is workload-dependent.
POST /v1/extract (single + batched)	POST /v1/extract (1 scrape credit per URL + metered managed-LLM cost) or POST /v1/scrape with formats: ["json"] + a JSON schema	Matched, including a urls array of up to 50 URLs per request.
POST /v1/deep-research	GET /v1/search/research/papers	Matched via the Research API. 61.0% recall vs Firecrawl's 53.3% on the public ArXivQA benchmark.

To migrate: point your existing Firecrawl SDK or HTTP client at the fastCRW base URL (the official firecrawl crate works via its self-hosted constructor — v1 FirecrawlApp::new_selfhosted, v2 Client::new_selfhosted; pin a version), and keep the overlap-surface calls (/v1/scrape, /v1/crawl, /v1/map, /v1/search, /v1/extract) unchanged. Code on the overlap surface does not change.

Head-to-head: firecrawl vs fastcrw

Decision area	fastCRW	Firecrawl
Overlap-surface compatibility	✅ /scrape, /crawl, /map, /search	✅
Anti-bot / block bypass	✅ open-core (12-signal block detection, UA rotation, proxy rotation)	✅ Cloud-only Fire-engine
Self-host shape	Single Rust binary	Docker Compose stack
Memory baseline (self-host)	Low idle footprint	~1-2 GB
Cold start (self-host)	Fast local cold start	~5-15s
Public benchmark	63.74% truth-recall (522 of 819 labeled URLs), 91.8% scrape success of reachable URLs, 0 errors — full latency distribution + one-command repro on /benchmarks	Run the same dataset under different run conditions to compare
MCP support	✅ built-in crw-mcp	✅ official firecrawl-mcp-server
LLM extraction surface	/v1/extract (urls array up to 50; 1 scrape credit per URL + metered managed-LLM cost); /v1/scrape formats: ["json"] + jsonSchema	/v1/extract (single + batched, Cloud)
Standard managed plan	$69/mo, 100k credits	$83/mo, 100k credits
Free self-host	✅ AGPL-3.0 single binary	✅ AGPL-3.0 Compose stack
Best for	Teams that want Firecrawl-style scraping in one lightweight, self-hostable binary with open-core anti-bot	Teams already deep in Firecrawl Cloud's dashboard and billing workflows who don't need self-host

The benchmark numbers describe our framing on a public labeled corpus — they are not a universal truth for every workload. Cite the methodology before quoting the numbers.

Pricing math (affordable web scraping service instead of firecrawl)

Managed-plan headline prices (verify within 48h before quoting):

Plan	Firecrawl	fastCRW
Free	1k credits/mo	500 one-time lifetime credits (never resets)
Hobby	$16/mo, 5k credits	$13/mo
Standard	$83/mo, 100k credits	$69/mo, 100k credits
Growth	$333/mo, 500k credits	$279/mo
Scale	$599/mo, 1M credits	$549/mo

At every paid tier above Free, fastCRW is between $13 and $54/month cheaper for the same nominal credit budget. That gap exists because both vendors are pricing infrastructure, and fastCRW's runtime is lighter — that engineering choice flows into the price.

The honest caveat: at very high volume both vendors will be more expensive than self-hosting on a $40-100/month VPS. AGPL-3.0 self-host is free in license terms; you pay for the server, the bandwidth, the search-stack upstream rate-limit risk, and your own ops time. The break-even depends on traffic shape — at 1M+ scrapes/month most teams are better off self-hosting.

Why teams switch

The typical move from Firecrawl to fastCRW happens when:

1. Self-host weight matters more than expected. The Firecrawl Compose stack (API + workers + Postgres + Redis) is heavier than a single Rust binary on a small server.
2. The team needs MCP without adopting an extra moving part. Both products ship MCP; fastCRW's is built into the same binary.
3. /v1/extract is matched. fastCRW takes a urls array (up to 50 URLs per request), billed as 1 scrape credit per URL plus the metered managed-LLM cost, and /v1/scrape with formats: ["json"] + jsonSchema covers the single-page case.
4. The team is already in a Rust stack and wants their scraping server to match.

Where Firecrawl is still strong

• Mature hosted product with a longer track record and broader integrations matrix.
• Established Rust SDK (firecrawl crate) — the official path for Rust callers, also works against fastCRW via the crate's self-hosted constructor (v1: FirecrawlApp::new_selfhosted, v2: Client::new_selfhosted — pin a version; see the self-hosted Rust crate page for the version-pin guidance).

Where fastCRW wins

• Lighter self-host story. Single Rust binary vs Compose stack.
• One stack for /scrape, /crawl, /map, /search with built-in MCP — no extra services to deploy.
• Anti-bot built into the open core. 12-signal block detection, user-agent rotation, stealth fingerprints, and proxy rotation ship in the AGPL binary — Firecrawl's Fire-engine equivalent is Cloud-only, and its OSS self-host has none.
• Full JS-rendering escalation, no manual config. Auto ladder HTTP → LightPanda → Chrome (CDP) → proxied Chrome, plus an optional Camoufox stealth renderer, built in rather than bolted on.
• AGPL-3.0 OSS with the same self-host commercial path Firecrawl offers.
• Lower headline price on managed plans at every paid tier.
• Research API. fastCRW ships a drop-in Research API mirroring Firecrawl's Research Index endpoints (search/inspect/read papers, citation-graph expansion, research GitHub). On the public ArXivQA benchmark it reaches 61.0% recall vs Firecrawl's Research Index 53.3% — live retrieval, no self-hosted index. Point the Firecrawl research SDK at api.fastcrw.com.
• For Rust callers: the official firecrawl crate works against fastCRW via its self-hosted constructor (v1: FirecrawlApp::new_selfhosted, v2: Client::new_selfhosted — pin a version), so client code is portable.
