| Plan | Monthly | Annual | What you get |
|---|---|---|---|
| Open Source | Free | — | AGPL-licensed open-source outliner free forever with local Markdown plus Org-mode files, bidirectional links, and graph view |
| Sync | $5.00/mo | $60.00/yr | $5 per month annual ($8 monthly) for end-to-end encrypted sync across devices; the only paid tier |
Logseq is the AGPL-licensed open-source pick and the cleanest free-forever option in this lineup. Founded 2020 by Tienson Qin with a distributed team, Open Source is genuinely free with no paid features hidden behind a wall and the full source code on GitHub at around 33,000 stars. For a reader who wants a defensible free-forever posture with auditable source and self-host capability, Logseq is the honest answer.
Open Source covers AGPL self-host with local Markdown plus Org-mode files, bidirectional links, graph view, and no accounts required. Sync is the only paid tier at five dollars a month annual, with end-to-end encrypted multi-device sync and 5GB storage. There are only two tiers, which makes the free-forever promise straightforward to verify against the vendor site rather than buried under tier-comparison clauses.
The trade-off versus Obsidian Personal is plugin breadth (around 150 community plugins versus more than 1,500 on Obsidian) and UX polish in the early-2026 builds. The trade-off versus Notion Free is collaboration; Logseq is single-user-first and is rough for shared workspaces. For solo budget-conscious readers who want auditable source and a free-forever posture, Logseq leads.
