Fastest Browser Use

A Rust-based browser automation engine that provides a lightweight binary driving Chrome directly via CDP. It is optimized for token-efficient DOM extraction, robust session management, and speed.

🧪 Recipes for Agents

1. Bypass "Bot Detection" via Human Emulation

Simulate mouse jitter and random delays to scrape protected sites.

fast-browser-use navigate --url "https://protected-site.com" \
  --human-emulation \
  --wait-for-selector "#content"

2. The "Deep Freeze" Snapshot

Capture the entire DOM state and computed styles for perfect reconstruction later.

fast-browser-use snapshot --include-styles --output state.json

3. Login & Cookie Heist

Log in manually once, then steal the session for headless automation.

Step 1: Open non-headless for manual login

fast-browser-use login --url "https://github.com/login" --save-session ./auth.json

Step 2: Reuse session later

fast-browser-use navigate --url "https://github.com/dashboard" --load-session ./auth.json

4. 🚜 Infinite Scroll Harvester

Extract fresh data from infinite-scroll pages — perfect for harvesting the latest posts, news, or social feeds.

# Harvest headlines from Hacker News (scrolls 3x, waits 800ms between)
fast-browser-use harvest \
  --url "https://news.ycombinator.com" \
  --selector ".titleline a" \
  --scrolls 3 \
  --delay 800 \
  --output headlines.json
