firecrawl

Firecrawl is an open-source web scraping and data extraction API that converts websites into clean markdown or structured JSON. It handles JavaScript-heavy sites, rotating proxies, and rate limiting automatically, with both self-hosted and hosted service options.

What firecrawl is

TypeScript-based web crawling framework exposing REST/SDK endpoints (search, scrape, interact, agent, crawl, batch) that parse HTML/JS content, apply LLM-ready transformations, and support agentic interaction patterns. AGPL-3.0 licensed with active development and substantial community adoption.

Quickstart

Get the firecrawl source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/firecrawl/firecrawl.gitcd firecrawl# follow the project's README for install & configuration

Best use cases

AI Agent Data Collection

Feed web-sourced content directly to LLM-based agents via MCP or SDK; handles content normalization to reduce token consumption.

Enterprise Data Pipeline

Self-host for regulated environments; scrape and structure web data at scale without managing proxy infrastructure.

Real-Time Product Intelligence

Monitor competitor websites, pricing pages, job listings with sub-4s latency; interact with dynamic content before extraction.

Implementation considerations

  • AGPL-3.0 imposes copyleft obligation: any modifications must be shared; commercial wrapper services may require separate licensing.
  • Hosted API relies on API key auth; self-hosted requires deployment (Docker/K8s), network egress for web requests, and storage for results.
  • Rate limiting and proxy rotation handled server-side; client code is thin, but cost/quota management needed for high-volume scraping.
  • LLM-optimized output (markdown, tokens) assumes downstream use in AI pipelines; pure data export may require additional post-processing.
  • JavaScript rendering included (no separate headless browser setup), but adds latency; batch operations available for throughput.

When to avoid it — and what to weigh

  • Proprietary closed-source mandate — AGPL-3.0 requires sharing modifications; if you cannot open-source derivative work, license incompatibility exists.
  • Simple DOM-only scraping — Over-engineered for basic static HTML extraction; lightweight cheerio/jsdom alternatives are more resource-efficient.
  • SaaS with zero third-party dependencies — Hosted service depends on firecrawl.dev infrastructure; self-hosted still requires maintenance and scale planning.
  • Compliance with strict robots.txt enforcement — Tool is designed for broad web coverage; transparent respect of robots.txt may not be configurable per use case.

License & commercial use

AGPL-3.0 (GNU Affero General Public License v3.0). Copyleft: modifications or network-accessible derivative works must release source. Commercial use of unmodified library is permitted; commercial use of modified versions requires disclosure or separate license.

Using unmodified Firecrawl in a commercial product is legally permissible under AGPL-3.0. However, if you modify the source or integrate deeply into proprietary systems, the copyleft clause may trigger disclosure obligations. Evaluate licensing with counsel if you plan to fork or heavily customize; check if the maintainers offer commercial licensing alternatives.

Security considerations

AGPL-3.0 is open-source: code is auditable, but no formal security audit disclosed in data. Scraping web content at scale introduces attack surface (SSRF risks, malicious payloads in crawled HTML, rate-limit evasion). Self-hosted deployments expose egress to the internet; isolate via VPN/proxy and monitor resource usage. Hosted service handles auth via API keys; treat as secrets. No mention of encryption, data retention, or compliance certifications in provided data.

Alternatives to consider

Bright Data (formerly Luminati)

Commercial web scraping platform with managed proxy network, JS rendering, and compliance tools. Proprietary; higher cost but turnkey for enterprise with compliance audits.

Apify

OSS and SaaS web scraping framework with visual actors and cloud execution. Permissive license; focus on low-code workflows rather than API-first agentic patterns.

Cheerio / Playwright / Puppeteer

Lightweight DOM parsing and headless browser control libraries. Require manual proxy/rate-limit management but offer fine-grained control and are MIT/Apache licensed.

firecrawl FAQ

Can I use Firecrawl in a commercial product?
Yes, if unmodified. Under AGPL-3.0, commercial use of the library as-is is permitted. Modifications or deep integration may trigger copyleft obligations; review with legal counsel if you plan substantial customization.
Does Firecrawl support headless browser rendering?
Yes. JavaScript-heavy pages are rendered server-side; no client-side Puppeteer setup needed. Latency is ~3.4s P95 for rendered content.
How do I integrate Firecrawl with an AI agent?
Use MCP (via firecrawl-mcp-server) for Claude/compatible clients, or install the CLI skill with `npx firecrawl-cli@latest init --all --browser`. REST API and SDKs are also available.
What happens if I fork and modify Firecrawl?
Under AGPL-3.0, if the modified version is used over a network (hosted), you must disclose the source code. For internal-only changes, simpler rules apply, but network distribution triggers disclosure. Consult the license or seek commercial licensing from maintainers.
