Cloud API and usage

Coming soon. WhittleBrowser Cloud is not open yet. This page will hold the API reference and the usage and billing details when it is.

Cloud is the open-source engine run on our servers: browsers for your agents behind an API, and a live view where a person finishes a login, CAPTCHA or 2FA step while the agent waits.

There is no sign-up, no billing and no release date today. To hear when it opens, join the waitlist.

What works today

Everything else in these docs is available now, and it is free and open source:

• Getting started: connect Claude Code, Codex, Cursor or any MCP client to a real browser in one command.
• How it works and the protocol: what the model sees and every tool.
• Safety model: what is kept from the model and what waits for you.
• Host control: embed the engine in your own app.
