OpenAI’s new macOS app lets developers run multiple AI coding agents in parallel

OpenAI released the Codex app for macOS on February 2, 2026. The app acts as a command center to run multiple AI coding agents in parallel. Developers assign tasks—feature work, bug fixes, and testing—to isolated worktrees to avoid repository conflicts. A library of agent skills covers fetching Figma designs, managing Linear projects, generating images, and deploying to Cloudflare or Vercel. Automations run scheduled background jobs that produce CI/CD summaries and refactor code, queuing results for review. Native sandboxing restricts agent access to approved folders and enforces granular permissions. Built on the GPT-5.2-Codex model, the app extends prior CLI and web tools and positions OpenAI against Anthropic's Claude Code. It is available now to ChatGPT Plus, Pro, Business, Enterprise, and Education users, with temporary free access and doubled rate limits. Over 1 million developers used Codex in the past month.

Why It Matters

• Ship features faster: run parallel agents on isolated worktrees to implement features and fix bugs concurrently, cutting cycle time from days to hours.
• Automate operations: use built-in skills for Vercel/Cloudflare and scheduled CI/CD summaries to reduce manual maintenance and speed deployments.
• Scale oversight: engineering leads monitor agent progress and review queued results without losing context, improving sprint throughput and coordination.
