Welcome to Kunkun
Open-source app launcher and productivity tool.
Kunkun is an open source app launcher and productivity tool — an alternative to Alfred, Raycast, and uTools. It's built for speed, security, and extensibility.
What can I do with Kunkun?
- Launch anything — apps, files, URLs, and custom commands — with a keyboard shortcut
- AI-powered search — index your local files, codebases, notes, and web pages, then search and ask questions with natural language
- Extend with plugins — install extensions from the store for clipboard management, file conversion, system monitoring, and more
- Local API — expose RAG search and other features to external tools over HTTP
