APISelf is an innovative desktop marketplace featuring local-first applications that double as APIs and MCP (Model Context Protocol) tools. Designed for developers and power users, APISelf allows you—alongside AI clients like Claude Desktop or Cursor—to call these applications directly right from your machine.

Built with privacy and cost-efficiency in mind, everything runs locally on your computer, functions seamlessly offline, and ensures your data stays entirely with you. Abandoning the traditional SaaS model, APISelf features no subscriptions; instead, every app is available via a simple one-time unlock. For features requiring cloud AI, users can bring their own API keys which remain safely stored locally, allowing you to pay third-party providers directly at cost. A free launcher and free tier are available forever.
