The free, open-source Roam alternative

Logseq is what happens when an open-source developer falls in love with Roam Research's outliner-first approach and decides to build the privacy-respecting version. Your graph is a folder of plain Markdown or org-mode files on your disk — no cloud lock-in, no subscription, no telemetry. Block-level references, bidirectional links, daily journaling, and a strong plugin ecosystem are all free forever. The 2026 release added Logseq AI (using GPT-4o or local models) that lives entirely on your machine if you want it to.

Who it's for: Open-source enthusiasts, privacy-focused professionals, researchers, and anyone who wants Roam-style outliner workflows without the subscription or cloud dependency.

Key features

100% Free & open-source

AGPL-licensed. No paywalled features, no Pro tier hiding the good stuff. Funded by community donations and an optional Logseq Sync service.

Outliner Outliner-first like Roam

Every page is a hierarchical bullet list. Tab to indent, Shift+Tab to outdent. The fastest way to take structured notes that's ever existed.

[[]] Bidirectional links + graph

Same Roam-style [[link]] and block references, plus a force-directed graph view. Backlinks are automatic and surfaced in-context.

Local Local-first, privacy-first

Your data is a folder of plain-text Markdown or org-mode files. You can read them in 50 years with any text editor. No telemetry, no cloud required.

The honest take

✓ What works

Completely free, fully open-source — no upsells, no Pro tier
Local-first means true data ownership and 10-year durability
Outliner UI is faster than Notion or Obsidian for structured notes
Active Discord community of power users
Works offline perfectly — no internet required

✗ What doesn't

Mobile app is still rough compared to Obsidian and Roam
Sync across devices requires Logseq Sync ($5/mo) or self-hosted workaround
Plugin ecosystem is smaller than Obsidian (though growing fast)
Performance degrades on graphs with 10K+ pages (large PKM users hit this)

Verdict

If you want Roam's outliner workflow but refuse to pay $15/mo or hand your notes to a cloud, Logseq is the clear winner. It's the most Roam-like experience that's still 100% free and open-source. For an even deeper plugin ecosystem, pick Obsidian. For real-time cloud collab, pick Notion.
