Rill Browser

Rill Browser is a free Mac browser that integrates Claude Code and Codex agents to execute tasks directly from web pages.

Rill Browser is a free application for macOS designed to run coding agents directly inside your web browsing experience. It integrates with Claude Code and Codex, allowing you to send tasks from any webpage and continue browsing while the agent works in the background. The browser automatically discovers your projects from your existing history without setup and groups your tabs by activity. Agents can read the web, compare tabs, and handle tasks while operating securely on your local machine using your Keychain and accounts. It is built for developers who want to delegate coding and research tasks without leaving the browser interface. It supports standard browser features like imported sign-ins and private windows while adding AI-driven tab sorting, project mapping, and voice commands.
