bb-browser Skill

Overview

bb-browser connects to your running Chrome via CDP (Chrome DevTools Protocol) and executes fetch() / JS in your logged-in tabs. No scraping, no API keys — your browser is the API.

v0.11.6 | 143 community adapters | 36 platforms

Prerequisites

1. Chrome must be running with remote debugging enabled:

   # macOS
   /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222
   
   # Linux
   google-chrome --remote-debugging-port=9222
   
   # Or restart if already running:
   pkill chrome && sleep 1 && google-chrome --remote-debugging-port=9222 &
   

2. Verify: bb-browser status should show connected browsers.

OpenClaw Integration

bb-browser supports --openclaw flag to use OpenClaw's built-in browser (no Chrome needed):

bb-browser site reddit/hot --openclaw
bb-browser site xueqiu/hot-stock 5 --openclaw --json

重要: bb-browser daemon连接的是OpenClaw的隔离Chrome（/tmp/agent-browser-chrome-...）， 与OpenClaw browser tool的Chrome（~/.openclaw/browser/openclaw/user-data）是不同进程。

Twitter/X特别说明: Twitter的ct0 cookie是HTTP-only，bb-browser的JavaScript无法读取。 但OpenClaw browser tool（CDP协议）可以。Twitter数据抓取应使用专用脚本： scripts/twitter-scraper.py（Playwright连接OpenClaw browser CDP）。

架构: bb-browser daemon → 端口9222 → 找到的第一个Chrome（含OpenClaw的） Playwright: 直接连接 http://127.0.0.1:18800 → OpenClaw browser

bb-browser eval "document.title"   # Execute JS
bb-browser fetch <url> --json      # Authenticated HTTP fetch
bb-browser screenshot [path]       # Take screenshot

Utility

bb-browser tab list                # List open tabs
bb-browser status                  # Browser connection status
bb-browser network requests        # View network requests
bb-browser console                 # View console output
bb-browser site update             # Update community adapters
bb-browser site recommend          # Suggest adapters based on history

Output Formats

All site commands support:

• --json — structured JSON output
• --jq '<filter>' — jq filtering (e.g., --jq '.items[] | {name, price}')

Example:

bb-browser site xueqiu/hot-stock 5 --jq '.items[] | {name, changePercent}'
# {"name":"云天化","changePercent":"2.08%"}
# {"name":"东芯股份","changePercent":"-7.60%"}

Adapter Tiers

Tier	Method	Speed	Examples
1	Cookie fetch	~1s	Reddit, GitHub, V2EX
2	Bearer + CSRF token	~3s	Twitter, Zhihu
3	Webpack/Pinia injection	~10s	Twitter search, Xiaohongshu

Use from OpenClaw Agent

Quick data fetch (exec)

# In agent exec calls:
bb-browser site twitter/search "BTC price" --json 2>&1
bb-browser site xueqiu/stock SH000001 --json 2>&1

For login-gated sites

If web_fetch returns 403/blocked, try bb-browser:

bb-browser fetch "https://api.binance.me/api/v3/ticker/price?symbol=BTCUSDT" --json 2>&1

Limitations

• Not for bulk scraping — designed for single/few queries, not millions of records
• Rate limits apply — you're operating as your real account; excessive use = ban risk
• Chrome must stay open — daemon connects to running Chrome instance
• No headless — the whole point is using your real browser session

Troubleshooting

Issue	Fix
No browsers connected	Start Chrome with --remote-debugging-port=9222
Tab not found	Check bb-browser tab list, site may need to open first
Login required	Manually log into the site in Chrome first
--openclaw fails	Ensure OpenClaw browser is available (browser doctor)
Adapter missing	bb-browser site update to pull latest

Writing Custom Adapters

bb-browser guide                    # Read the adapter writing guide
bb-browser site info <name>         # Check existing adapter

Each adapter is a single JS file. Submit to bb-sites repo for community use.
