About OctBlog

Join the chat at Build Status

OctBlog is almost the same with MayBlog except that it is powered by Flask and MongoDB rather than Django and SQL Databases.

And as my customary, I named it OctBlog as OctBlog was started in October, 2015

OctBlog offers every function in MayBlog, and aims to do it better, its features are as follow:

  • Multiple user
  • OctBlog roles: su, admin, editor, writer, reader
  • Blog features: posts, pages, tags, and categories
  • Markdown support
  • Admin interface
  • Change configurations by configuration file or environment variable
  • Multiple comment plugin
  • User defined widgets
  • Deploy with docker
  • Sort posts by weight


Gevin's Blog is powered by OctBlog


The weight is used to order articles, and if you want to hidden an article from the article list, weight is also qualified:

The default weight for each article is 10, if a article's weight is heavier than 10, it will be firstly displayed, and if the weight is negative, the article will be never displayed in the article list

I'm not good at frontend development, so I used a free bootstrap blog theme. If you can redesign the blog theme and admin interface, I'll appriciate your work very much!
