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.

bb-browser guide # full tutorialTell 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.
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:
