TiddlyWeb is a reference implementation for an interface to put Tiddlers on the web.
It was created by a team led by Chris Dent at Osmosoft under BT from 2008 to 2012.
TiddlyWeb can be used to host TiddlyWiki and TiddlyWiki5 wikis, making the individual tiddlers available over a flexible HTTP API.
Other implementations of the API include:
As of early 2017, none is currently as complete as TiddlyWeb itself.
