TiddlyWiki
TiddlyWiki is a unique self-contained wiki that lives in a single HTML file. Created by Jeremy Ruston, it is a non-linear personal web notebook where all your notes, ideas, tasks, and journal entries are stored in one portable file that works entirely in the browser with no server required. Because everything is in one file, your knowledge base travels with you — copy it to a USB stick, sync it with any cloud service, or serve it from a tiny Node.js process.
Key Features
- Single-file architecture — The entire wiki, including content and logic, is one HTML file that runs offline in any modern browser
- Non-linear note-taking — Interlink ideas with wiki-style links, tags, and transclusion to build a personal web of knowledge
- Powerful filtering — Use TiddlyWiki’s expression language to slice and filter notes by tags, fields, dates, and custom attributes
- Extensible plugins — Hundreds of plugins and themes add functionality from code highlighting to Kanban boards
- Works everywhere — Run it as a static file, as a Node.js server, or on AWS Lambda and other serverless platforms
- Privacy by design — Your notes never leave your machine unless you choose to sync or publish them
Why Use TiddlyWiki?
TiddlyWiki is ideal for people who want total ownership of their notes with zero dependency on cloud services or subscription apps. It is one of the most flexible knowledge management tools in the FOSS ecosystem — you can shape it into anything from a simple diary to a sophisticated research database without learning to code.
