A main advantage of Flynn over using docker-compose is that Flynn is more aware of how to run applications out-of-the-box, rather than just running containers which the user has to fully configure.

For example, Flynn comes with PostgreSQL, MariaDB and MongoDB appliances which are deployed in a highly available, fault tolerant configuration with sane defaults: https://flynn.io/docs/databases.

Through the use of buildpacks, it is also straight forward to deploy applications written in many popular languages and frameworks without being intimately acquainted with how to containerise those types of applications (e.g deploying a Ruby on Rails app on JRuby: https://flynn.io/docs/languages/ruby).

You also get things like full cluster backups (including all your data), simple git / docker / tarball based deployments, log aggregation, release rollbacks, domain / path based routing, service discovery, and many more!
