About DeepNotes

DeepNotes is an open-source note-taking tool built around an infinite canvas rather than a linear document. Pages can be nested to any depth, so ideas can be explored in detail without crowding a single surface, and notes are protected with end-to-end encryption.

Users can create groups to collaborate in realtime, organize notes in whatever structure suits them, and rely on what the project calls lifelong storage. The codebase is TypeScript, using Vue and the Quasar framework, Yjs for collaboration, Tiptap for rich text, and KeyDB or Redis for shared memory and communication.

According to its development commands, the same code can be run as a single-page app, a server-side rendered app, an Electron desktop app, or Android and iOS builds. DeepNotes is released under AGPL-3.0, and a hosted version is available at deepnotes.app.
