Juno

Open-Source SDK for building apps·juno.build

Juno is an open-source, full-stack platform for building, deploying, and running web apps in WASM containers with zero DevOps. It bundles hosting, authentication, a key-value datastore, file storage, serverless functions (written in Rust or TypeScript), and privacy-focused analytics into a single SDK, CLI, and web Console workflow. Apps run in a decentralized, stateful environment on the Internet Computer, giving developers full ownership of their code, data, and infrastructure. The product is currently in maintenance mode and is no longer actively developed.
