Juno is an open-source serverless platform for hosting static websites, building web applications, and running serverless functions with the privacy and control of self-hosting.

It provides a familiar cloud experience with strong security and zero operational complexity. Each project runs in its own WASM container, fully owned and controlled by you.

Think of it as Vercel + Firebase + Self-Hosting - without the compromises.
