Juno is an open-source, next-gen serverless platform to build, deploy, and run modern apps with the privacy and control of self-hosting.

Juno is your own self-contained execution space.

No DevOps. No backend boilerplate. No surprise complexity.

You build your frontend using the frameworks you love — React, SvelteKit, Next.js, you name it.

Need backend logic? Just drop in a serverless function written in Rust or TypeScript.

Everything gets bundled into a single deployable WebAssembly (WASM) container. One artifact. One push. That's your app. It runs in an unstoppable environment that holds its entire state — data, logic, and storage.
