Reaper Daemon is the daemon you let into REAPER, a small local bridge that lets Claude Code, Codex, or any AI agent drive your DAW. Ask in plain English; it makes the real edit in your real project. Humanized drum grooves written into your kit. Surgical EQ on an actual plugin, and it tells you why. No browser extension, no server, no MCP. 100% local, and every edit is one undo away.
Share stems, leave timestamped feedback, and keep the conversation where the work is. The layer between your DAW and the people you make music with. Free 5GB forever.
1. $0 to run. It ships with a fallback chain of seven free OpenRouter models. Every other kit either charges you monthly or pushes you onto a paid API from day one. This one costs $19 once and then nothing.
2. No frameworks. No LangChain, no vector database, no embeddings, no agent orchestration layer that breaks every six months. It's 400 lines of plain Python with requests and json. You can read the whole thing in 20 minutes.
