View guide →Trilium — build your personal knowledge base: a hierarchical notes app with strong encryption, scripting and sync, maintained by the TriliumNext community
Trilium is an open-source productivity project by TriliumNext (TriliumNext/Trilium on GitHub). It has 38,375 GitHub stars and 2,582 forks, is released under the AGPL-3.0 license, and was last updated on GitHub on 17 October 2026.
Download the desktop build for your platform from the project releases or triliumnotes.org — or deploy the server edition with Docker for browser access from anywhere.
Create notes and organise them in the hierarchy; clone a note to make it appear under several parents without duplicating it.
Connect desktop and server instances to sync, and mark sensitive notes as protected — they are encrypted with your password and unreadable without it.
Hierarchies with cloned notes in multiple places, hoisting, and search fast enough for tens of thousands of notes.
Protected notes are encrypted at rest inside the database; the rest of the tree stays quick and open.
Rich text, code with syntax highlighting, tables, canvas, mind maps, calendars, geo-maps and more in one app.
Attributes, relations and a JS API let notes behave like small apps — dashboards, trackers, automations.
Grab the build for Windows, macOS or Linux from the releases page.

Yes — AGPL-3.0 licensed, desktop and self-hosted server alike.
Desktop for a single-machine knowledge base; the server edition (or both, synced) when you want browser access from anywhere and multi-device use.
Against Joplin, Trilium offers a richer hierarchy, per-note encryption and scripting, while Joplin is simpler and stronger on mobile apps and sync-provider choice. Against Notion, Trilium is self-hosted and offline-capable — your base runs on your hardware.
Install the desktop build from the releases page, create your first notes, then add the Docker server later if you want sync.
