Malicious code in crw (PyPI)

The client's default API endpoint is https://fastcrw.com/api — a lookalike of firecrawl.com — to which the pub

README

fastCRW — Self-hosted, Rust-native web crawler & scraper for AI agents

The open-source alternative to Firecrawl. One static binary, ~50 MB RAM idle, Firecrawl-compatible REST API (/v1/scrape, /v1/crawl, /v1/extract, /v1/map, /v1/search) plus first-class MCP. Self-host free under AGPL-3.0, or hit our managed API at api.fastcrw.com. Reproducible 63.74% truth-recall on the public 1,000-URL dataset (diagnose_3way.py, 2026-05-08) — see fastcrw.com/benchmarks. Built in Rust because every millisecond of agent latency compounds.

Works with: Claude Code · Cursor · Windsurf · Cline · Copilot · Continue.dev · Codex · Gemini CLI

Why fastCRW?

Rust-native, single static binary — no Redis, no Node.js, no Python venv, no headless-browser sidecar in the request path. One binary, one config file, one process.
~50 MB RAM idle — leaves headroom on a $5 VPS. Browser-render-first stacks (Firecrawl, Crawl4AI) carry a Chromium heap baseline measured in hundreds of MB before a single request lands.
Firecrawl-compatible drop-in — same /v1/scrape, /v1/crawl, /v1/extract, /v1/map, /v1/search endpoints with compatible request/response shapes. Swap the base URL and keep your code.
AGPL-3.0 open core + managed option — self-host free, or point at api.fastcrw.com for managed proxy network, dashboard, and SLA without the AGPL obligations on your application code.
