TiddlyWiki is a very solid looking platform for IndieWeb use (essentially using TW as a personal website). I am having some issues with the js;dr (cURL-ability) issue, but there are some methods for using it to create a static website.
To help others out and provide some examples, I’ve started a stub page for TiddlyWiki on the IndieWeb wiki, which uses MediaWiki. (If you have the rel=”me” stuff set up in the second article about h-card linked below, you should be able to use your TiddlyWiki URL to log into the IndieWeb wiki and document yourself, changes, and ideas.) 

 
I’ve been writing up some of my explorations using TiddlyWiki for IndieWeb on my primary website (with copies on my TiddlyWiki) for those who are interested in taking a look or experimenting for themselves.

Self-hosting TiddlyWiki with GitHub Pages
An h-card for my TiddlyWiki
Webmention for TiddlyWiki to enable website to website notifications and communication

For those interested in following my particular progress, you can find all of my related content on my site with this tag: https://boffosocko.com/tag/tiddlywiki/ or follow via RSS at https://boffosocko.com/tag/tiddlywiki/feed/.
 
For those who are interested in delving in further, I might suggest looking at my IndieWeb/TiddlyWiki To Do List for things that could potentially be worth working on next:

adding proper h-entry and h-feed microformats markup 
adding microformats markup and/or customizing tiddlers as articles, notes, bookmarks, and other types of posts
backfeed of comments from Twitter, Flickr, Instagram, GitHub, Mastodon using Brid.gy
adding a full implementation of webmentions for core

figuring out the js;dr problem for sending webmentions

Adding set up to potentially allow posting to TiddlyWiki using Micropub (may run into js;dr problems?)
Look into using TiddlyWiki as a Micropub server
Adding header information for using TiddlyWiki with Microsub readers (this should be fairly easy)

There is a lot of open source code in a variety of languages that does a lot of this stuff already in addition to lots of examples, so do search the IndieWeb wiki or ask in the IndieWeb chat for help or pointers so that you won’t necessarily need to reinvent the wheel.
