We are thrilled to share with the HN community the second preview of BrowserCode: A FOSS web app to run TUI agents (such as Claude Code, OpenCode, Gemini CLI and the like) fully in the browser. This release focuses on Claude Code and initial support for mobile. BrowserCode is released under the Apache License, version 2.0.
BrowserCode is based on BrowserPod (https://browserpod.io), a in-browser WebAssembly-based code sandboxing technology that can currently run Node.js, python, git, bash and many other command line tools. This will further expand to Ruby / Rails, Go, Rust and eventually x64 Linux binaries.
BrowserCode is free to use and unlimited. You'll need to login to each CLI with the corresponding login, i.e. with your Anthropic account or API key. All the data and execution stays completely local to the browser and it's persistent across sessions thanks to a disk backend based on the Origin Private File System API or IndexedDB.
This is a preview release, so please try and break it! Please report issues on GitHub and star the repo if you like our work. Your support will help us push this project forward.
