I've just started to use my own self-hosted Docker-based installation of Kaneo (after a short test of the free SaaS version).
What can I say? It's awesome. Indeed, it's not bloated, navigation is short and precise. Integration with Garage (S3) went well and smooth. So far I love everything about Kaneo (except probably the favicon which looks pale on my gray bookmarks bar in Chrome, but that's trivial).
What I like most about Kaneo? - Intuitive, concise everything. Responsive UI. I don't need documentation, it's such a relief after Jira and many others I've been forced to work with.
