What is Dokku?
Dokku is an open source Platform as a Service (PaaS) that provides a Heroku-like experience for deploying and managing applications. Powered by Docker, it can be installed on any hardware, allowing users to own their PaaS without vendor lock-in. Once set up, Heroku-compatible applications can be pushed via Git, built using Heroku buildpacks, and run in isolated containers. Dokku supports application lifecycle management from building to scaling, making it a lightweight and extensible alternative for single-host deployments.
