How is it different to Obsidian?
* A single-file Tiddlywiki is a single file that only requires a web browser to be used (e.g., you can email it to someone and they can just open it)
* Tiddlywiki is extremely customizable, much more than obsidian. It's almost hard to describe, but you can make very interesting things with just basic knowledge about html and css.
To cite myself:
> the problem with TiddlyWiki is that it's hard to describe since its so flexible. I have a few local tiddlywikis that I use for catalogues and note taking/knowledge base. The note taking was inspired by another HN comment [3] that introduced Drift [4,5], which includes features such as tabs for backlinks, keywords, and freelinks. But you may also find the Projectify edition [6] interesting or one cloning Roam Research [7].

Rather different from a closed-source desktop file editor.
