No API keys, no proxies, no CDP Chrome. Free from the Flow team.

FlowCrawl

Scrape any website. Bypass any bot protection. Free.

Install Scrapling First

pip install scrapling

Scrapling installs Playwright automatically on first run. That's the only dependency.

Quick Usage

# Single URL — prints clean markdown to stdout
python3 ~/clawd/skills/flowcrawl/scripts/flowcrawl.py https://example.com
Spider the whole site
python3 ~/clawd/skills/flowcrawl/scripts/flowcrawl.py https://example.com --deep
Deep crawl with limits, save and combine
python3 ~/clawd/skills/flowcrawl/scripts/flowcrawl.py https://example.com --deep --limit 30 --combine
JSON output — pipe into anything
python3 ~/clawd/skills/flowcrawl/scripts/flowcrawl.py https://example.com --json

Add Alias (Recommended)

echo 'alias flowcrawl="python3 ~/clawd/skills/flowcrawl/scripts/flowcrawl.py"' >> ~/.zshrc
source ~/.zshrc

Then just: flowcrawl https://example.com

How It Works

FlowCrawl uses a 3-tier fetcher cascade. Starts fast, escalates only when blocked:

| Tier | Method | Handles | |------|--------|---------| | 1 | Plain HTTP | Most sites, instant | | 2 | Stealth + TLS spoof | Cloudflare, Imperva, basic WAFs | | 3 | Full JS execution | SPAs, heavy JS, aggressive bot detection |

Auto-detects blocking (403, 503, "Just a moment...") and escalates silently.

All Options

| Flag | Description | Default | |------|-------------|---------| | --deep | Spider whole site following internal links | off | | --depth N | Max hop depth from start URL | 3 | | --limit N | Max pages to crawl | 50 | | --combine | Merge all pages into one file | off | | --format md\|txt | Output format | md | | --output DIR | Output directory | ./flowcrawl-output | | --json | Structured JSON output | off | | --quiet | Suppress progress logs | off |
