Dokku is an open-source Platform-as-a-Service (PaaS) that allows developers to quickly deploy and manage their applications on their own servers. It is similar to Heroku and Deis and is powered by Docker. It enables developers to deploy any application type (including web, mobile, and big data applications) quickly and easily. It also provides a variety of features such as application-level networking, automatic scaling, and easy management of environment variables. Additionally, it supports a wide range of languages, frameworks, and databases, making it an ideal choice for developers looking to quickly get their applications up and running.
