A block-based notebook that keeps every note as a file in a workspace folder you own, with links between blocks and search across all of them.

What it is
A block-based note application. Block-based means each paragraph is a thing you can link to, move or reuse on its own, not just text in a page. It stores a workspace folder you can back up, copy or read with any other program.
What it is good for. Anyone who has lost notes to a service closing, or who simply wants the file on their own disk. It is the self-hosted answer to the well-known paid notebooks, and the block linking makes it genuinely different from a folder of text files.
- 19 open issues and 3 open pull requests — an unusually small backlog for a project of this size.
- Ready-made installers for Windows, macOS and Linux, so no building is involved.
- Version 3.8.6 of 29 September 2026, with pre-release builds on 1, 3 and 4 October. It is moving fast.
- Keeping two devices in step is a paid feature. The project lists a one-time charge of 64 US dollars for syncing through storage you supply, and 148 US dollars for its own cloud service with 8 GB. The README's line that most features are free for commercial use does not mention that the one most people want is not.
- AGPL-3.0, and the licence file names no copyright holder beyond the Free Software Foundation's own line. Running a modified copy as a service for others brings real obligations.
- No memory, disk or processor figure is published anywhere. Building from source needs two separate toolchains and a manual step to fetch Electron 42.9.2 by hand, so for most people the installer or the container is the only sensible route.
- logseq/logseq
The same block-linked idea over plain Markdown files, and more popular; its README currently warns that the newer database version is in beta and that data loss is possible.
