Start building with Codex
Codex works as a coding agent that can complete well-scoped tasks in secure, isolated environments, with progress you can monitor in real time all from plain-language prompts. Whether you’re prototyping an idea, optimizing a system, or debugging a tricky issue, Codex integrates into your workflow to help you build and ship more efficiently.
Why it matters for builders
- Code generation from natural language: Quickly scaffold projects, add features, or generate boilerplate code.
- Code understanding: Get clear explanations for complex logic and dependencies.
- Refactoring & optimization: Improve efficiency and maintainability without altering intended behavior.
- Multi-language support: Works across popular programming languages, frameworks, and libraries.
- Automating repetitive tasks: Offload well-scoped engineering work like refactoring, renaming, and writing tests to stay focused on higher-value work.
