Awesome Codex

English | 简体中文

A curated list of tools, skills, MCP servers, AGENTS.md patterns, and resources for OpenAI Codex.

Codex is OpenAI’s agentic coding agent — a terminal CLI, an IDE extension, and a cloud environment that share the same agent. This list focuses on the community ecosystem around it, plus the official docs worth bookmarking.

What makes this list different: it is updated every week, and entries are kept alive. Dead links get removed, not archived. If a section stops being useful, it gets deleted. See OPERATIONS.md for the maintenance contract.

Legend: (Official) by OpenAI · (Chinese) Chinese-language resource · (Paid) paid or freemium · everything else is community/open source.
