@cocktailpeanut4/21/2026, 6:25:40 PMOwner

OpenAI just open sourced Euphony, a minimal web UI to browse and search all your Codex sessions . Works on ALL OS (Mac, Windows, Linux)

https://github.com/openai/euphony

And you can use it with 1-click.

By default Euphony requires you to enter the file URLs manually, but this launcher automatically discovers all your codex session files and displays them as well.

To learn more about Euphony, check out their announcement post: https://x.com/OpenAIDevs/status/2046620363568890230?s=20
