One-command install

curl -fsSL https://fastcrw.com/install | sh

Runs local and free, no account needed. To use the Cloud, paste your key into the same command and it installs the binary, connects the key, and registers the MCP server with the AI coding tools you already have:

curl -fsSL https://fastcrw.com/install | CRW_API_KEY=crw_live_... sh

crw search "rust tutorials"

Claude Code, Cursor, Codex, Gemini CLI, OpenCode and Windsurf are picked up automatically when they are already set up; nothing else is touched, and your key stays in ~/.config/crw/config.toml rather than being copied into each tool. Add CRW_NO_AGENTS=1 to skip that step, or run crw setup on its own to choose interactively.

1000 free credits, no credit card. Managed proxies, JS rendering and search, with nothing to run or keep up to date. Get my free key →

Why fastCRW

On Firecrawl's own public 1,000-URL dataset, fastCRW recovered more truth than Crawl4AI and Firecrawl, matched the fastest median latency, and idled at ~14 MB RAM.

_{Methodology, full numbers, and how to reproduce it}

On a different benchmark entirely, answer accuracy rather than scrape recall, fastCRW answers 90.0% of the 600 AA-Omniscience questions correctly. Every product listed on the Artificial Analysis Search Index sits below it.

Choose how you use it

CLI

crw https://example.com            # scrape, works right after install
crw search "rust async runtime"    # search, after `crw setup`

Python SDK

Using Cloud? Get an API key, then export it once:

export CRW_API_KEY="crw_live_..."
pip install crw

from crw import CrwClient

client = CrwClient()
page = client.scrape("https://example.com", formats=["markdown"])

print(page["markdown"])

npm install crw-sdk

import { CrwClient } from "crw-sdk";

const client = new CrwClient();

const page = await client.scrape("https://example.com", {
  formats: ["markdown"],
});

console.log(page.markdown);

MCP for AI agents

npx -y crw-mcp@latest install

Installs the CRW skill and MCP server in your detected AI tools. crw setup can also do this step, so either path is enough. Manual setup →
