Juno
Open-source serverless platform for modern apps with self-hosting
What is Juno? Complete Overview
Juno is an open-source, next-generation serverless platform designed for developers who want to build, deploy, and run modern applications while maintaining the privacy and control of self-hosting. It provides a container-based environment where developers can quickly implement their ideas without worrying about infrastructure management. Juno is particularly valuable for teams and individuals who prioritize data sovereignty and want to avoid vendor lock-in while still benefiting from serverless architecture's scalability and ease of deployment. The platform combines the flexibility of containerization with the simplicity of serverless computing, making it ideal for startups, indie developers, and enterprises looking for a modern development platform.
