Obsidian is a Markdown-based knowledge management tool that stores everything as local files on your device. It has a plugin ecosystem, a graph view for visualizing connections between notes, and a loyal community that has built thousands of extensions for it. But Obsidian has real limitations that become obvious once
If you're evaluating MediaWiki and XWiki, you already have a certain kind of problem. You need something open-source. You probably need self-hosting. And you've likely looked at the lighter wiki tools on the market and decided they don't have the power you need for
Every few months, the same question shows up on Reddit, Hacker News, and a dozen Slack communities: should we use Notion or Coda? The thread fills with people who swear by one and dismiss the other. Both sides usually talk past each other because they're solving different problems.

BlueSpice started as a good idea. Take MediaWiki, the engine behind Wikipedia, and make it usable for companies. Add a visual editor, better permission controls, some enterprise features on top.
