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}

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"])

Node.js

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);
