Introducing the Codex app
Today we’re releasing the Codex app for MacOS, a command center for managing multiple coding agents in parallel. The app lets you run long‑horizon and background tasks, review clean diffs from isolated worktrees, see agent progress and decisions, and execute reusable skills and automations.
Available with ChatGPT plans that include Codex, with a limited‑time promo: Free and Go can try Codex with included limits, while Plus, and Pro users get 2x Codex rate limits.
