2 Free & Open-Source Roam Research Alternatives
Roam Research popularized bidirectional linking between notes, but it has no free tier at all — a subscription is required from day one. Logseq offers the same linked, block-based note model as a genuinely free and open-source tool, while Obsidian (free for personal use, though not fully open-source) is the other widely-used option in this space.
The best Roam Research alternatives
Logseq
Our top pickOpen sourceDesktop appA free, open-source, block-based linked notes app.
Logseq mirrors Roam's core idea closely — bidirectional links, a daily-notes journal, block references — as a genuinely open-source, local-first tool with no subscription for any tier.
- Bidirectional linking between notes and blocks
- Daily-notes journal workflow
- Local-first storage as plain Markdown/Org files
- Free, open-source, desktop and mobile apps
Obsidian
FreeDesktop appA widely-used, free-for-personal-use linked notes app.
Obsidian isn't open-source, but its core app is free for personal use indefinitely, with a large plugin ecosystem that extends it well beyond Roam's feature set — worth knowing about even though it's a different licensing model than the other tools here.
- Bidirectional linking and a graph view of your notes
- Large third-party plugin and theme ecosystem
- Local-first storage as plain Markdown files
- Free for personal use; paid tiers for commercial/sync use
Licensing and pricing models change over time — confirm current terms on each project's own site before making a procurement or compliance decision.
Frequently asked questions
Which is the better free alternative to Roam Research?
Logseq if open-source matters to you — it's the closer philosophical match to Roam's original outliner-first design. Obsidian if you want the larger plugin ecosystem and don't mind it not being open-source.
Can I import my Roam Research graph into Logseq or Obsidian?
Both can import Roam's JSON/Markdown exports, though some Roam-specific formatting may need manual cleanup after import.
Is Obsidian really free, given it's not open-source?
Yes for personal use — the core app has no cost or feature paywall for individuals. Obsidian charges for commercial use and for its optional cloud sync/publish services, not for the base note-taking app itself.
