What is Dokku?

Dokku is an open-source Platform as a Service (PaaS) solution that enables developers to deploy and manage applications on their own infrastructure. It serves as a lightweight and cost-effective alternative to cloud platforms like Heroku, offering the ability to deploy apps using Docker containers. Dokku’s extensibility, simplicity, and self-hosting capabilities make it a perfect fit for small to medium-sized teams. As an MIT-licensed platform, Dokku provides complete control over deployment processes while offering integration with various databases and services.

By eliminating the need for third-party cloud providers, Dokku helps avoid vendor lock-in while offering cost-effective and customizable solutions for app deployment. Its open-source nature means you can tailor the platform to your team’s unique needs and workflows.
