TiddlyHoster is shared hosting service for TiddlyWeb entities (bags, recipes and tiddlers) built on TiddlyWeb. Like TiddlySpace it can provide hosting for TiddlyWiki documents, but it provides a more bare metal and hackable environment for dealing with bags and recipes, especially the authorization policies.

There is a public service at http://hoster.peermore.com/
The code is at http://github.com/cdent/tiddlyhoster
