Codex CLI is built for real engineering work across multiple surfaces. Get tasks and projects done from start to finish with autonomous agent workflows, right from your terminal.
An AI agent that edits code, runs experiments, checks results, and keeps only the changes that improve your project.
The agent proposes a change, runs the task, reads the result, and keeps only the changes that improve the outcome. Every cycle is a real iteration.
All engineering decisions stay inside your codebase. Every edit is easy to inspect, compare, and review before it becomes permanent.
The development process becomes the thing being optimized. Codex CLI turns repetitive tasks into autonomous loops you can trust.
Use Codex CLI across your editor, terminal, and CI pipelines. Same agent, same context, connected by your account.
Every change is surfaced as a clear diff. Review, refine, and approve — you stay in control of what goes into the codebase.
Automate PR reviews, scan for vulnerabilities, and run agent workflows locally or in the cloud. Enterprise-ready from day one.
One codebase, one agent, and one feedback loop keep the system narrow enough to inspect and strong enough to iterate.
The agent reads your project context, understands the task, and decides what changes to propose in the codebase.
Architecture, logic, configuration, dependencies — the agent edits the files that matter for the task at hand.
Every change gets tested under real conditions. The agent runs the relevant commands and checks the results.
Improvements stay. Regressions get rolled back. The agent iterates until the task is done — or hands control back to you.
Most tools automate execution. Codex CLI automates the cycle of proposing, testing, and deciding.
The development process becomes the thing being optimized. Codex CLI runs feedback cycles so you don't have to.
The edit surface stays narrow enough to inspect at a glance. Every change is surfaced before it lands.
Built from the ground up for autonomous workflows, not retrofitted. Codex CLI speaks the language of agents.
Start here if you want to know what Codex CLI is, how it works, and how to get started — without reading the whole page.
Codex CLI is an AI-powered assistant that works across your terminal, editor, and CI pipelines. It autonomously proposes changes, runs tasks, and keeps only the improvements — turning development into a repeatable feedback loop.
Codex CLI works across multiple surfaces — your local terminal, VS Code editor, CI/CD pipelines, and cloud environments. Your account connects context across all of them.
Most tools automate single steps. Codex CLI automates the full loop — propose, execute, verify, decide. It's an autonomous agent, not just a code completer.
Yes. Codex CLI is built for real engineering work — PR reviews, vulnerability scanning, prototype builds, bug triage, and multi-step tasks that span multiple files and services.
Codex CLI offers enterprise-ready security controls, advanced analytics, 100+ integrations, and pay-as-you-go pricing with no seat fees. Run agent workflows locally or in the cloud.
Getting started takes minutes. Download the CLI, connect your account, and point it at a project. Codex CLI will read your codebase and start helping immediately.
