About Openbrowserclaw
This platform is a personal AI assistant that runs entirely inside a web browser, with no server, container or cloud deployment required. The browser itself acts as the operating environment, using IndexedDB and the origin private file system for storage and Web Workers for processing.
The assistant is powered by Anthropic's Claude through the user's own API key, which the site says is encrypted with AES 256 GCM and stored locally. Claude works in a full tool use loop and can run code, manage files, and fetch URLs. A sandboxed Alpine Linux virtual machine, emulated in WebAssembly, lets it execute shell commands without touching the host machine. Users can also connect a Telegram bot to chat with the assistant from elsewhere, and create recurring tasks with cron expressions that run on a schedule in the browser. It installs as a progressive web app on phone, tablet or desktop.
The project is aimed at developers and hobbyists who want an always available agent without renting a virtual private server or dedicating a spare computer. It can be tried directly in a browser tab, or cloned from GitHub and run locally with npm.
The software is open source under the MIT license. No paid plans are published. Usage costs come from the user's own Anthropic API account.
