What is Logseq?
Logseq is a privacy-first, open-source outliner for knowledge management, built around local plain-text files (Markdown or Org-mode) instead of a proprietary cloud database, so users retain full control and portability of their notes. The app centers on a graph-based structure of bidirectionally linked pages and blocks, a daily-journal-first workflow inspired by Roam Research and TiddlyWiki, and native PDF annotation. A plugin ecosystem lets users add custom themes and functionality, and a SQLite-based database version is in beta for improved performance on large graphs. Because notes live as local files, users can version them with Git, sync them through their own cloud storage of choice, or keep them entirely offline. Logseq is licensed under AGPL-3.0 and available as desktop apps for Windows, macOS, and Linux, a web app at app.logseq.com, and an iOS app, with Android support still in development. A first-party real-time collaboration and sync feature (RTC) is in alpha testing and requires opt-in through a signup form, but as of now Logseq has no paid tier — the entire product, including any current sync functionality, is free.
Logseq is a free, open-source outliner and knowledge management tool that stores notes as local plain-text Markdown or Org-mode files rather than in a proprietary database, giving users full ownership of their data. It's licensed under AGPLv3, available for Windows, macOS, Linux, and web, with an iOS app and Android in development, and offers bidirectional linking, a daily-journal workflow, PDF annotation, and a plugin ecosystem for customization. Logseq is built for individuals who want a local-first, privacy-respecting alternative to cloud-based note apps like Notion or Roam Research, and it's entirely free with no paid tier; a real-time collaboration and sync feature is in alpha testing but not yet a commercial product. Logseq has 44,500+ stars on GitHub and a 4.9/5 rating from 65 reviews on Product Hunt.
Standout feature: Notes are stored as local plain-text Markdown or Org-mode files rather than a proprietary database, so users can version them with Git, sync through any cloud provider they choose, or work entirely offline.
Biggest weakness: Real-time collaboration and multi-device sync are still in alpha testing and require opt-in signup, so teams that need reliable built-in sync today must rely on third-party file-sync tools, and Android support remains in development while iOS is already available.
Pros
- Completely free and open source (AGPL-3.0) with no paid tier or feature gating.
- Local-first plain-text storage (Markdown or Org-mode) keeps notes portable and outside vendor lock-in.
- Bidirectional linking and a daily-journal workflow suit outliner-style thinking better than document-first note apps.
- Plugin ecosystem and native PDF annotation extend the app without needing a separate tool.
Cons
- Built-in real-time collaboration and sync (RTC) are still in alpha and require opt-in, not yet a reliable production feature.
- Android app is still in development, while competitors offer mobile apps on both platforms already.
- Outliner-based, block-structured notes have a learning curve for users coming from document-style editors like Notion.
- As a volunteer/community-driven open-source project, there is no paid support tier or SLA to fall back on.
