Laverna is a JavaScript note-taking web application with a Markdown editor and encryption support. It's built to be an open source alternative to Evernote.

The application stores all your notes in your browser databases such as indexedDB or localStorage, which is good for security reasons, because only you have access to them.

Demo: OR


  • Markdown editor based on Pagedown
  • Manage your notes, even when you're offline
  • Secure client-side encryption
  • Synchronizes with cloud storage services (currently only with Dropbox and RemoteStorage)
  • Three editing modes: distraction free, preview, and normal mode
  • WYSIWYG control buttons
  • MathJax support
  • Syntax highlighting
  • No registration required
  • Web based
  • Keybindings


On the front-end this project uses JavaScript and the Marionette JS framework while Node JS, Bower, and Gulp.js are used on the back-end. The test runner used is karma however, contributors are free to utilize whatever testing tools they desire.


There are several ways to start using Laverna:

  1. Open and start using it. No extra steps are needed.
  2. Use a desktop app.
  3. Use a prebuilt version from Laverna/static-laverna repository.
  4. Build it from the source code.

codesign -s - -f ./\ Framework.framework
codesign -s - -f ./\ Helper\

codesign -s - -f ./ 
codesign -s - -f ./ 
codesign -s - -f ./ 
codesign --verify -vv ./

Coding Style Guidelines

For those wanting to contribute code, we ask that you use either plain JavaScript or the Marionette.js framework. (For more details on the preferred coding style see .editorconfig). Also, all experimental changes are being pushed on the dev branch, so any feature changes are preferred to be done on either this branch or a branch that uses the dev branch as its parent.
