About TiddlyWiki

TiddlyWiki is a personal web notebook with a non-linear structure, usable by anyone and kept indefinitely without depending on any company. It is a complete interactive wiki written in JavaScript, in which content is stored as small units called tiddlers that can be linked, tagged and rearranged.

It can be used as one self-contained HTML file in the browser, or run as a Node.js application with a client and server setup for advanced users. The whole interface is implemented in WikiText, which makes it highly customizable, and there is a plugin ecosystem. The project description also mentions that it can run in places such as AWS Lambda.

The community talks on the Talk TiddlyWiki forum, a Google Group that dates back to 2005, GitHub Discussions, Reddit and Discord, and developer documentation is published on the project site. The repository lists the licence as Other. TiddlyWiki is suited to personal knowledge bases, journals, task lists and small documentation sets.
