Uploaded tiddlywiki to alwaysdata, was incredibly simple and free. They also provide https authentication.
My tiddlywiki journey
- Started with single tiddlywiki file
- Made alwaysdata account
- In backend go to Web then to Sites
- Remove default at free subdomain
- Install new application
- Choose tiddlywiki
- Change /www to something like /tiddly
- Just dragged my single tiddlywiki file into the alwaysdata tiddlywiki, works!
