Free Chromium-based macOS browser that runs Claude Code, Codex, or Cursor agents in tabs alongside terminals, PRs, and localhost servers.
Radius is a free Chromium-based browser for macOS that functions as an IDE by running Claude Code, Codex, or Cursor directly in browser tabs alongside diff viewers, terminals, PRs, docs, and localhost servers in one window. Projects are organized into spaces and worktrees into tab groups; the full setup is scriptable via Radius CLI. Worktrees, sessions, and agent state remain local; credentials authenticate directly with providers. No additional subscription is required beyond existing agent plans. Radius is a product of Radius.
