Superagent

A terminal is a thin place for a coding agent to live. Superagent is a native macOS app that gives one a workspace instead: a real browser it can drive, an iOS Simulator it can tap and swipe, a git worktree per conversation, and chats that survive quitting the app.

The browser pane is a genuine browser session with your existing logins, so the agent can sign in to a staging environment or a dashboard the way you would rather than fighting a headless shell. Alongside it, a real iOS Simulator streams from its own framebuffer — nothing to install — so an agent working on a mobile build can tap through the result. A dual-viewport mode renders the same page at desktop and phone widths in one live session, which makes "does the hero hold up on mobile?" a question the agent can answer itself.

Each chat runs on its own branch through a git worktree, so parallel experiments never touch your main checkout. Sessions and their context persist across restarts, and a companion iPhone app puts you in the loop remotely: approve a step or redirect a run from your phone, over an end-to-end encrypted relay.

Superagent supports Claude Code today, with Codex and Antigravity listed as coming next, and it drives whatever agent subscription you already pay for rather than reselling tokens.
