OpenPeon
Open standard for sound packs across AI coding tools and IDEs
Visit openpeon.com ↗What is OpenPeon?
OpenPeon defines CESP (Coding Event Sound Pack Specification), a universal format for audio feedback in agentic coding environments. Developers get sound notifications when tasks complete, errors occur, or input is needed—eliminating the need to constantly check for status updates. The standard works across Claude Code, Cursor, Codex, and any IDE that implements it.
The platform hosts 364+ community-created sound packs ranging from gaming nostalgia (Warcraft, StarCraft, Team Fortress 2) to pop culture references. Creators write a single JSON manifest to build a pack; IDEs map their own events to nine standardized categories. The maker says it was built with Claude Code.
