Pros and cons

+ what works
  • +Local-first: notes are plain Markdown or Org-mode files on disk, no lock-in
  • +AGPL-3.0 licensed; clients are fully open source and auditable
  • +Block-level linking, backlinks, and graph view, similar to Roam Research
  • +End-to-end encrypted optional Sync using age, with the user holding the key
  • +Works offline with no account required
watch out for
  • The database (DB) version rewrite has been in beta for years and lives alongside the legacy file-based version, fragmenting docs and plugins
  • New mobile app and real-time collaboration sync are still in alpha as of late 2025
  • Smaller plugin ecosystem than Obsidian, with some plugins not yet ported to the DB version
  • Funding situation is unclear since the 2022 seed round; long-term roadmap depends on a small team
  • Outliner-only model is a poor fit for users who want freeform long-form documents

Privacy notes

Logseq stores graphs as plain Markdown or Org-mode files in a local folder, so notes never leave the device unless the user opts into sync or third-party storage. The desktop and mobile apps work fully offline and require no account. Logseq Sync is an optional paid add-on that end-to-end encrypts blocks with age before uploading to Logseq's servers, so the operator sees only ciphertext. Logseq Inc. is incorporated in the United States, so US legal process applies to anything the hosted Sync service holds.
