Codex is OpenAI's coding agent that can read, edit, and run code. It helps you build faster, fix bugs, and understand unfamiliar code. With Codex cloud, Codex can work on tasks in the background (including in parallel) using its own cloud environment.
Codex is OpenAI's autonomous coding agent designed to understand, write, and improve code on your behalf. It runs in a secure cloud environment, connected to your GitHub repositories, and can complete complex engineering tasks end-to-end without manual intervention.
Codex analyzes your entire codebase — from directory structure to import graphs — building a comprehensive understanding before making any changes.
From adding new features to refactoring existing code, Codex generates clean, well-structured code that follows your project's conventions.
Codex executes code in its cloud sandbox, runs tests, and validates that changes work before proposing them back to you.
Delegate tasks that run in the cloud — including in parallel across multiple workspaces — while you stay focused on what matters most.
Codex Web combines the power of large language models with a secure cloud runtime to autonomously build, debug, and improve your software.
Codex operates in its own cloud sandbox with full access to install dependencies, run tests, and execute code safely without affecting your local machine.
Connect your GitHub account and Codex can read repositories, create branches, make commits, and open pull requests with proposed changes.
Run multiple Codex agents simultaneously across different tasks or repositories — each in its own isolated cloud environment, all in parallel.
Write clearer prompts with constraints, context, and the right level of detail. Codex understands complex multi-step instructions and breaks them down.
Delegate tasks directly from your editor. Kick off a cloud task from VS Code or JetBrains, then monitor progress and apply diffs locally.
Control whether Codex has internet access from its cloud environment. Enterprise workspaces offer admin-managed security policies and governance.
Start with proven patterns for delegating tasks, reviewing changes, and turning results into production-ready pull requests.
Describe what you need — from "fix this bug" to "build the authentication flow" — and Codex takes it from there. Include relevant context, constraints, and acceptance criteria for best results.
Codex works autonomously in the cloud. It reads your codebase, makes changes, runs tests, and iterates until the task is complete — all while you continue working on other things.
Codex presents changes as clear diffs or pull requests. Review what was changed, run additional checks, request modifications, or merge directly when satisfied.
Once changes are merged, Codex can help with deployment scripts, monitoring setup, and post-deployment validation — closing the loop from development to production.

Getting started with Codex Web takes just a few minutes. Configure your environment and start delegating tasks to your AI coding agent.
Go to Codex Web and connect your GitHub account. This gives Codex access to read your repositories and create pull requests.
Codex is included with your Plus, Pro, Business, Edu, or Enterprise plan. Enterprise workspaces may require admin setup for governance.
Select the repository, specify setup steps, and choose which tools Codex should have access to when running tasks in the cloud.
Tag @codex on issues and pull requests, use the IDE extension, or prompt directly on the Codex Web platform to kick off tasks.
Everything you need to know about Codex Web and its cloud capabilities.
Codex is included with your Plus, Pro, Business, Edu, or Enterprise plan. Some Enterprise workspaces may require admin setup before you can access Codex. Check your plan details to confirm availability.
Codex runs in a secure cloud environment isolated from your local machine. You control whether code can access the public internet from the cloud environment. Enterprise workspaces offer additional security policies, governance controls, and admin-managed configurations.
Yes. Codex offers an IDE extension that lets you kick off cloud tasks directly from your editor. You can monitor progress in real-time and apply the resulting diffs locally. Supports VS Code and JetBrains IDEs.
Yes. With Codex cloud, you can run multiple Codex instances simultaneously — each in its own isolated environment — working on different tasks or repositories in parallel. This is particularly useful for larger projects with many independent work items.
Simply tag @codex on issues and pull requests. Codex will automatically spin up a cloud task, analyze the context, make changes, and propose a solution directly on the thread. This enables seamless AI collaboration within your existing GitHub workflow.
Yes. You can configure whether Codex is allowed to reach the public internet from its cloud environment. This is an important security control for enterprises handling sensitive codebases. Internet access can be toggled per workspace or managed globally by admins.
