Logseq

Open-source outliner for linked, block-level notes

Overview

Logseq is an open-source outliner in which every note is a list of blocks that can be referenced and linked individually, with a daily journal page as the default entry point. Its GitHub repository describes it as a privacy-first, open-source platform for knowledge management and collaboration, licensed under AGPL-3.0, and shows about 45,600 stars[22]. Desktop builds are distributed through the repository’s releases page and a web app runs at app.logseq.com[22].

Logseq is in the middle of a large architectural change. The repository states that the new database (DB) version is in beta, that the new mobile app and RTC real-time sync are in alpha, and warns that data loss is possible, recommending backups and a dedicated test graph[22]. The original file-based version, which stores pages as Markdown files on disk, remains the stable route.

Logseq suits people who think in outlines and want block references, queries and a graph of linked ideas without paying a licence. Its limitations are the transition risk documented by the developers themselves, sync that is still in alpha, and an outliner-only model that feels unfamiliar to users who want free-form documents. Obsidian covers similar ground with a more stable release cadence.
