What is it?

OpenNotas is a personal note-taking application built as a Progressive Web App, so it runs in a browser and can be installed on mobile, Windows, Linux and macOS. It focuses on quickly writing plain-text notes with a simple interface, and supports Markdown in its editor.

Notes can be synced across devices through a configurable adapter. Note data is encrypted with AES before it leaves the device and reaches the sync server, so the server only stores encrypted content.

The project is written in Vue and built with Nuxt 3, and it is licensed under AGPL-3.0-or-later. Users can run the PWA from the hosted site or build it from source.

Things to know

  • The README says the license is AGPL-3.0-or-later, which is copyleft and requires source sharing for modified network use.
  • The author asks contributors not to submit new feature pull requests and expects delays in responses.
  • Sync requires configuring an adapter, so setup takes extra effort.
