Best for a personal wiki kept in one file you control

TiddlyWiki is a whole wiki in a single HTML file: your notes and the software together, opening in a web browser with nothing to install. It's free, open source and endlessly tweakable with plugins, macros and filters. The catch is the fiddling. You have to pick a way to save before your changes stick, and notes are written in its own WikiText markup.

Who TiddlyWiki is for

  • Great if you want your notes in one file that you fully control
  • Handy when you like tinkering with plugins, macros and filters
  • Good for publishing a small wiki or documentation site as static HTML

Who TiddlyWiki is not for

  • Skip it if you want to open an app and just type, because saving has to be set up first
  • Not for you if you want Markdown out of the box, since notes use its own WikiText
  • Tight if you live on your phone, as the mobile apps come from independent developers

Why TiddlyWiki gets a 3.4

  • CEase of useNo rating on record, and there's a hurdle on day one. The browser's File / Save menu doesn't save your changes, so you first choose a saving method such as Tiddlyhost or TiddlyDesktop. Notes are in its own WikiText too, with Markdown only through a plugin.
  • BPlatforms and integrationsIt opens in a web browser on Mac, Windows and Linux, and the Node.js server lets phones and tablets edit the wiki in a browser. The iOS and Android apps its docs point to, Quine and Tiddloid, are published independently of the project. No integrations are on record.

What is TiddlyWiki?

TiddlyWiki is an open-source notebook that keeps its content and its code together in one HTML file, which opens in a web browser without an install. Notes are small linked units called tiddlers, written in its own WikiText markup and organized with links, tags and filters. It can also run as a Node.js server that stores each tiddler as a separate file, and plugins extend it.

Good for

  • People who want their notes in a file they fully control
  • Tinkerers who customize a notebook with plugins, macros and filters
  • Publishing a small wiki or documentation site as static HTML

Worth knowing

  • The browser's File / Save menu does not save changes; a saving method such as Tiddlyhost or TiddlyDesktop has to be chosen first.
  • Notes are written in TiddlyWiki's own WikiText markup; Markdown is available only through an official plugin.
  • The iOS and Android apps the documentation points to, Quine and Tiddloid, are published independently of the project.
  • The Node.js server does not pick up tiddler files edited on disk while it runs; it has to be restarted.

Key features

Single-file notebook
The whole wiki, content and code, lives in one HTML file that opens in a web browser with no install and no external dependencies.
Tiddlers, links and tags
Notes are small units called tiddlers, connected by links and tags. Each tiddler's info panel lists its backlinks and the tiddlers tagged with it.
WikiText and filters
WikiText covers formatting, links, transclusions and macros, and filters build lists of tiddlers by tag or field, such as a glossary.
Plugins
Optional plugins install from the official library or from community sites. The official set includes Markdown, KaTeX, CodeMirror and Highlight plugins.
Built-in encryption
A single-file wiki can be given a password and saved with AES 256-bit encryption, so the file asks for the password before showing any content.
Node.js server edition
Running on Node.js stores each tiddler as a separate file and lets any modern browser, including those on phones and tablets, edit the wiki.
