Rill
A free Mac browser where Claude Code and Codex agents work alongside you while you browse.
Overview
Rill is a free browser for macOS that integrates AI coding agents directly into your browsing experience. Built to work with Claude Code or Codex, it lets you send tasks to your agents from any webpage and keep browsing while they work in the background. Your agents automatically detect which project a task belongs to based on your browsing history, with no setup required.
The browser combines traditional browsing features with AI-powered capabilities: agents can research information in their own tabs, create files, modify code, and handle complex workflows—all while respecting your security and requiring explicit approval before making changes. Your browsing history is kept locally on your Mac and reads like a journal of what you asked for and what got done.
