The idea
The internet was built for browsers. AI agents have been trying to access it through APIs — but 99% of websites don't offer one.
bb-browser flips this: instead of forcing websites to provide machine interfaces, let machines use the human interface directly. The adapter runs eval inside your browser tab, calls fetch() with your cookies, or invokes the page's own webpack modules. The website thinks it's you. Because it is you.
| Playwright / Selenium | Scraping libs | bb-browser | |
|---|---|---|---|
| Browser | Headless, isolated | No browser | Your real Chrome |
| Login state | None, must re-login | Cookie extraction | Already there |
| Anti-bot | Detected easily | Cat-and-mouse | Invisible — it IS the user |
| Complex auth | Can't replicate | Reverse engineer | Page handles it itself |
Quick Start
Install
npm install -g bb-browser
Use
bb-browser site update # pull community adapters
bb-browser site recommend # see which adapters match your browsing habits
bb-browser site zhihu/hot # go
OpenClaw (no extension needed)
If you use OpenClaw, bb-browser runs directly through OpenClaw's built-in browser — no Chrome extension or daemon required:
bb-browser site reddit/hot --openclaw
bb-browser site xueqiu/hot-stock 5 --openclaw --jq '.items[] | {name, changePercent}'

10 minutes to add any website
bb-browser guide # full tutorial
Tell your AI agent: "turn XX website into a CLI". It reads the guide, reverse-engineers the API with network --with-body, writes the adapter, tests it, and submits a PR. All autonomously.
Three tiers of adapter complexity:
| Tier | Auth method | Example | Time |
|---|---|---|---|
| 1 | Cookie (fetch directly) | Reddit, GitHub, V2EX | ~1 min |
| 2 | Bearer + CSRF token | Twitter, Zhihu | ~3 min |
| 3 | Webpack injection / Pinia store | Twitter search, Xiaohongshu | ~10 min |
We tested this: 20 AI agents ran in parallel, each independently reverse-engineered a website and produced a working adapter. The marginal cost of adding a new website to the agent-accessible internet is approaching zero.
What this means for AI agents
Without bb-browser, an AI agent's world is: files + terminal + a few APIs with keys.
With bb-browser: files + terminal + the entire internet.
An agent can now, in under a minute:
# Cross-platform research on any topic
bb-browser site arxiv/search "retrieval augmented generation"
bb-browser site twitter/search "RAG"
bb-browser site github search rag-framework
bb-browser site stackoverflow/search "RAG implementation"
bb-browser site zhihu/search "RAG"
bb-browser site 36kr/newsflash
Six platforms, six dimensions, structured JSON. Faster and broader than any human researcher.
Also a full browser automation tool
bb-browser open https://example.com
bb-browser snapshot -i # accessibility tree
bb-browser click @3 # click element
bb-browser fill @5 "hello" # fill input
bb-browser eval "document.title" # run JS
bb-browser fetch URL --json # authenticated fetch
bb-browser network requests --with-body --json # capture traffic
bb-browser screenshot # take screenshot
All commands support --json output, --jq <expr> for inline filtering, and --tab <id> for concurrent multi-tab operations.
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%"}

Daemon configuration
The daemon binds to 127.0.0.1:19824 by default. You can customize the host with --host:
bb-browser daemon --host 127.0.0.1 # IPv4 only (fix macOS IPv6 issues)
bb-browser daemon --host 0.0.0.0 # listen on all interfaces (for Tailscale / ZeroTier remote access)
