OpenPeon
An open standard for coding event sounds. Any IDE, any pack, one format.
What is CESP?
The Coding Event Sound Pack Specification defines a universal format for sound packs that respond to IDE events — task completions, errors, permission prompts, and more. Write a pack once, use it everywhere.
Any IDE
Claude Code, Cursor, Codex, and more. One pack works across all tools that implement CESP.
183+ Sound Packs
From Warcraft Peons to GLaDOS to StarCraft units. Gaming nostalgia meets developer productivity.
Community Driven
Create your own pack with a single JSON manifest. Share it with the community via GitHub.
