Not on Reclaim, but I have tinkered with it many times over the years.

TW keeps evolving, and has a whole TiddlyWiki on Node.js – TiddlyWiki on Node.js: TiddlyWiki — a non-linear personal web notebook

Basically, you run a very simple node.js server, and it creates/reads/saves tiddlers as individual files to disk. You can visit in any browser and edit and so on. Mostly single user – I can’t really recommend TW for multi user, although I did run it for a time on Google AppEngine with some permission settings for multiple google accounts for logins.

One note, TiddlyWiki uses fragment (#) based routing, so unless you do a bunch of extra work to continuously generate a “Static” site, it becomes very hard to deep link into the site, and the SEO / search-ability of it from the outside is pretty terrible.

Since I’m doing lots of stuff with IPFS, I may at some point see about experimenting with this plugin GitHub - xmaysonnave/tiddlywiki-ipfs: Ipfs with TiddlyWiki
