OpenAI launches Codex Plugins to streamline developer workflows

Codex has become one of the fastest-growing businesses for OpenAI in the past few months. OpenAI recently highlighted that over 1 million developers used Codex in the past month alone, with overall usage doubling since the release of the GPT-5.2-Codex model.

Today, OpenAI announced that Codex is getting support for plugins. Plugins are installable bundles for reusable Codex workflows that will make it easier for developers to share the same setup with others. Basically, using plugins, developers can package skills, optional app integrations, and MCP server configurations in a single place. All the available plugins will be listed in the Codex directory and are available to use in the Codex app, Codex CLI, and IDE extensions.

OpenAI highlighted that skills and plugins are meant for different use cases. Developers should use skills when they are iterating on one repo or one workflow, the behavior is personal or project-specific, or they are experimenting before they package something reusable.

Developers should use plugins when they want the same skills or app integrations available across teams or projects, or when they want to bundle skills, MCP config, and app integrations into one installable unit. Skills can’t be published for others, while plugins can be versioned packages for others inside an organization or in the marketplace for the public.

We're rolling out plugins in Codex.

Codex now works seamlessly out of the box with the most important tools builders already use, like @SlackHQ, @Figma, @NotionHQ, @gmail, and more.https://t.co/PQDsLqHGA6 pic.twitter.com/TIbsIUAf6S

Slack, Figma, NotionHQ, Cloudfare, and Gmail are some of the plugins that are already available in the Codex Plugin Directory. The ability for developers to add plugins to the official Plugin Directory is coming soon. OpenAI highlighted that self-serve plugin publishing and management are also coming soon.
