TiddlyWiki is a great project. I used it for personal/internal documentation at work via Tiddly Desktop. What broke it for me is organizing things inside. ToC creation needs strict tagging, and there's no way to create a page hierarchy unless you create index pages yourself. As the number of pages proliferate, the overhead for organization became accidentally quadratic, so I exported everything to Markdown and moved to Obsidian. It's closed source, but it works. So, it's an acceptable trade-off for me. Don't let this discourage you though. Tiddly Wiki is great!
