Overview

Flynn is an open-source Platform as a Service (PaaS) that lets developers deploy, scale, and manage applications and databases on their own infrastructure. Built with Go and container-based technology, it provides a self-hosted alternative to Heroku with Git-based automated deployments and built-in PostgreSQL and MySQL databases plus automatic load balancing. It can run on a single server or across multiple nodes for high availability, giving users control over hosting and resources. Its goal is to offer a simple, scalable way to run apps on self-hosted infrastructure, delivering a familiar Heroku-like workflow with on-premises flexibility.
