About Codex

AIWatch Data: Based on AIWatch data from the last 30 days, Codex experienced 4 incidents with an average recovery time of 2h 5m. 30-day uptime: 100.00%.

Codex is a coding agent from OpenAI that runs across web, CLI, and a VS Code extension, using frontier OpenAI models to plan and execute multi-step code changes. This is the current Codex coding-agent product, not the deprecated 2023 Codex code-generation API.

AIWatch Insight: Codex shares its backend infrastructure with ChatGPT and the OpenAI API. When OpenAI has a broad platform incident, Codex is almost always affected — AIWatch tracks Codex independently so the impact scope is visible per surface (Codex Web, Codex API, CLI, VS Code extension). Codex-specific incidents that do not also affect ChatGPT are less common but do occur.

When Codex is down, developers lose the coding agent across the CLI, web, and VS Code extension — multi-step planning, file edits, and task execution all fail. The underlying OpenAI models may still be reachable via the API for other uses.

Frequently Asked Questions

Is Codex down right now?

Check the live status indicator at the top of this page. AIWatch monitors Codex every 5 minutes across its four published surfaces (Codex Web, Codex API, CLI, VS Code extension) and shows real-time operational status.

Is this the old Codex API from 2023?

No. This page tracks the current OpenAI Codex coding agent released as part of OpenAI's agent products. The 2023 Codex code-generation API was deprecated and is not what AIWatch monitors here.

Why is Codex not working?

Codex outages usually stem from one of: a broader OpenAI platform incident (also affects ChatGPT and the API), a Codex-specific backend issue, or an upstream model outage. Check the Recent Incidents section for current context.

What are alternatives to Codex?

Based on current AIWatch data, Cursor (Score: 93) and Windsurf (Score: 83) are the most reliable alternatives right now. When Codex is down, Claude Code, GitHub Copilot, Cursor, or Windsurf are alternative coding agents. AIWatch shows which are currently operational.

Which Codex surface does the uptime percentage track?

The 30-day uptime shown on this page reflects the Codex API component specifically, which backs the CLI and VS Code extension. Codex Web frontend outages may not be counted in that percentage — check the Recent Incidents section for surface-specific events across all four Codex surfaces (Codex Web, Codex API, CLI, VS Code extension).
