Dokku vs PythonAnywhere: What are the differences?
Developers describe Dokku as "Docker powered mini-Heroku in around 100 lines of Bash". Docker powered mini-Heroku. The smallest PaaS implementation you've ever seen. On the other hand, PythonAnywhere is detailed as "Micro PaaS for Python web apps. Develop and host Python from your browser". It's somewhat unique. A small PaaS that supports web apps (Python only) as well as scheduled jobs with shell access. It is an expensive way to tinker and run several small apps.
Dokku and PythonAnywhere can be categorized as "Platform as a Service" tools.
"Simple" is the primary reason why developers consider Dokku over the competitors, whereas "Web apps" was stated as the key factor in picking PythonAnywhere.
