Document with BookStack, an open source Confluence alternative
BookStack is an open source, web-based documentation system, that allows you to create a structured knowledge store for personal, team, or company use. BookStack focuses on ease-of-use and design to provide an experience suitable for an audience with, potentially, mixed skills in technology. It's built upon the PHP framework Laravel, with MySQL or MariaDB used as a datastore.
I built BookStack after attempting to find a documentation or wiki system for my workplace. Confluence was the closest option to suit my requirements but the user-based pricing introduced a barrier. The closed nature of Confluence also raised questions to the longevity of the documentation I'd be building. In the end, I decided to build my own platform to suit my needs. I released it under the MIT license to give back to the open source community that I'd come to love and benefit from over the years.
