Overview
Flynn is a self-hosted PaaS inspired by Heroku that lets you git-push deploy apps to your own infrastructure. It handles containerisation, routing, process scaling, database provisioning, and SSL automatically. While Flynn's development has slowed, it remains a solid reference implementation of a Heroku-compatible open-source PaaS.
Where it falls short of Heroku
- Project is largely unmaintained as of 2023
- No Kubernetes backend; scaling is limited to a bespoke cluster model
- Smaller ecosystem and community compared to Dokku or CapRover
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
