    TiddlyWiki

    TiddlyWiki

    A self-contained JavaScript wiki for the browser, Node.js, AWS Lambda

    TiddlyWiki5 is a mature, self-contained open-source personal wiki application and non-linear notebook implemented entirely in JavaScript that runs in the browser or a Node.js environment, letting users create, organize, and interlink small pieces of content called tiddlers without the need for a server backend or traditional hierarchical pages. Its entire application — including content, interface, and logic — can live in a single HTML file that users open and edit directly in a web browser, making it portable, offline-capable, and easy to share or archive without dependencies. Beyond its single-file form, TiddlyWiki5 can also run as a more traditional application via Node.js, enabling filesystem storage and plugin ecosystems to extend capabilities like rendering engines, themes, and automation tools.
