What Kunkun is

Kunkun is a free, open-source app launcher for Windows, macOS, and Linux. It launches commands and supports JavaScript extensions, including interfaces built with React, Vue, or Svelte. Extensions are available through a community store or can be installed from GitHub, npm, or tarball files. Store examples include Google Search, VSCode project opening, SQLite Browser, JSON Formatter/Inspector, YouTube Downloader, Letterboxd, Imgur, Zed, and Hacker News tools. Before installation, users can view an extension’s required permissions. Kunkun says unauthorized API access is blocked and logged, while extension submissions are personally reviewed before entering the repository. The application and community extension code can be examined on GitHub, and extensions are designed to be written once and run across platforms. Official downloads include macOS AArch64, x64, and Universal builds. The project describes itself as early-stage and a work in progress; extension-building questions are directed to Discord.
