The Codex app from OpenAI is a fresh desktop tool that's changing how developers handle AI-assisted coding. Launched on February 2, 2026, it's built specifically for macOS (Apple Computers) and serves as a dedicated command center for working with Codex, OpenAI's advanced AI coding agent.
@OpenAIDevs shared on X that OpenAI has launched the Codex app, a command center for building with agents that lets users manage multiple agents, run work in parallel, and collaborate on long-running tasks.
What Is the OpenAI Codex App?
At its core, the Codex app gives you a focused desktop space for managing multiple AI coding agents at once. Instead of chatting with one AI for code suggestions, you can spin up parallel threads, delegate tasks across projects, and supervise long-running work without losing context.
@benitoz shared on X that OpenAI has launched the Codex desktop app, describing it as a “command center” for running coding agents in parallel on macOS.
It's designed for real software engineering workflows, think building features, handling refactors, fixing bugs, or even routine maintenance, all powered by OpenAI's latest coding models.
Codex itself (the agent) is an AI that can read your codebase, write or edit code, run tests in isolated environments, and propose changes like pull requests.
The app brings that agentic power into a streamlined interface where agents operate in parallel, using built-in tools like Git integration and worktrees to keep everything organized and conflict-free.
Background on OpenAI Codex
Codex started as a research preview in mid-2025 as a cloud-based software engineering agent capable of tackling parallel tasks.
It's evolved from earlier OpenAI coding tech (like the origins tied to GitHub Copilot) into a more capable system powered by frontier models optimized for development.
Codex agents handle end-to-end work: understanding complex codebases, generating features from natural-language descriptions, refactoring, migrating libraries, and iterating until tests pass, all while following your instructions closely.
The process stays safe through sandboxed cloud environments that limit access (no unrestricted outbound network calls, controlled file writes), so your code and dependencies remain protected.
The Codex App in Detail
Released just yesterday (as of February 3, 2026), the Codex app is a standalone macOS application (optimized for Apple Silicon) that acts as your hub for agentic coding. It lets you:
-
Run multiple agents in parallel across different threads or projects
-
Use isolated Git worktrees so each agent's changes don't clash
-
Review diffs, add inline comments, stage/revert chunks, and commit directly in the app
-
Set up a skills library with prebuilt or custom "skills" that teach agents how to interact with tools like Figma, Linear, deployment platforms, or your team's specific workflows
-
Create automations for background tasks, such as issue triage, alerts, CI/CD monitoring, or repetitive maintenance
It integrates smoothly with your existing setup you can keep using VS Code (via the Codex IDE extension), the terminal (Codex CLI), or the web interface while the app handles the big-picture orchestration.
How the Codex App Works Step by Step?
Here's a typical flow:
-
Download and install the app from the official OpenAI site, then sign in with your ChatGPT/OpenAI account.
-
Connect your Git repos or local projects.
-
Create a new thread or project and describe the task in natural language (e.g., "Implement a user authentication API with JWT in this Node.js repo, including tests").
-
Codex sets up a sandboxed environment and worktree, reads the context, plans steps, and starts working writing code, running linters/tests, and generating diffs.
-
You monitor progress in the app, review changes side-by-side, comment for adjustments, or approve to merge/commit.
-
For bigger jobs, agents can run autonomously for extended periods (up to 30 minutes or more in some cases) before checking back.
Real-World Use Cases
-
Tackling large refactors in a monorepo without disrupting your main branch.
-
Migrating legacy code to a modern framework while agents handle incremental steps and tests.
-
Setting automations to monitor repos for bugs or security issues and propose fixes automatically.
-
Prototyping new features across multiple repos in parallel, then reviewing everything in one place.
Codex App vs Other Tools
The app stands out from other Codex interfaces:
|
Tool |
Where It Runs |
Best For |
|---|---|---|
|
Codex App |
macOS desktop |
Managing multiple agents & long tasks |
|
Codex IDE Extension |
VS Code / other IDEs |
Inline, context-aware coding help |
|
Codex CLI |
Terminal |
Scripted/automated workflows, CI/CD |
|
Web Interface |
Browser |
Quick access without install |
Compared to traditional AI assistants (like basic autocomplete tools), Codex emphasizes multi-agent coordination, isolated environments, and full-task completion not just line-by-line suggestions.
Requirements, Access, and Pricing
-
Platform: macOS only right now (Apple Silicon supported); Windows support is coming soon, and you can sign up for notifications.
-
Access: Available to ChatGPT Plus, Pro, Business, Edu, and Enterprise subscribers. For a limited time (as announced with the launch), it's also open to Free and Go users, with doubled rate limits for paid plans across all Codex surfaces (app, CLI, extension, cloud).
-
Pricing: Tied to your ChatGPT subscription no separate Codex fee mentioned. Rate limits have seen recent boosts for paid users to handle more intensive agent work.
How to Get Started?
Head to the official page at openai.com/codex or developers.openai.com/codex/app to download the macOS app (it's a .dmg file). Install, sign in, and connect your repos. Start simple: try a small task to get comfortable, then scale up. Explore the built-in skills library or create your own for team-specific conventions.
