Roam Research alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Block references, backlinks and outlines without making the outliner your entire personality.
licenseAGPL-3.0
runsyour machine or their cloud
installDesktop/mobile package, or Docker image for browser-based self-hosting
enginesBuilt-in AI features connect to OpenAI-compatible APIs using a configured endpoint and key
dataA workspace stores block documents as structured .sy JSON files plus assets on disk; SQLite files hold indexes and auxiliary state; documents can export to Markdown, HTML, PDF, and Word
the catch vs Roam ResearchSiYuan supports block references and backlinks but its outliner, graph queries, and collaborative editing feel less fluid and immediate than Roam's.
setupThe desktop app installs cleanly, but free cross-device sync is not a turnkey feature: official cloud sync is a paid membership feature and Docker hosting does not transparently become desktop/mobile sync

Roam's block graph, minus the monthly tribute and plus a folder you can inspect.
licenseAGPL-3.0

installDesktop or mobile installer from the official downloads/releases
dataThe established file-based edition stores pages as Markdown or Org files plus assets in a local graph folder; the newer database-backed edition uses a different local database model
the catch vs Roam ResearchLogseq closely matches the outliner, but its sync and collaboration story is less mature and its transition between file and database editions adds uncertainty.
setupThe first decision is whether to stay on the mature file-based edition or adopt the newer database edition and its migration path; either way, sync and backups need deliberate setup

Bidirectional links and block references in plain files; the outline comes from plugins.
licenseproprietary, free

installOfficial desktop or mobile installer
dataEach vault is an ordinary folder of Markdown files plus local attachments and configuration; optional paid Obsidian Sync stores end-to-end-encrypted replicas in Obsidian's service
setup✓ installs clean
the catch vs Roam ResearchObsidian is page-and-file-centric rather than a block-native outliner, so Roam's fluid block references, daily-note capture, and block queries require plugins and workarounds.

Roam Research: People pay for a writing surface they trust for years, plus migration tools, sync, and tiny interaction details that disappear into habit. If none of that applies to you, any pick above saves $180 a year.
Is there a free alternative to Roam Research?
Yes: SiYuan, Logseq, Obsidian. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Roam Research?
Our verdict is SÍ. Roam Research's solo core is compact: build a local-first networked notes app with fast capture, full-text search, backlinks, tags, and Markdown export. A competent builder can reach a useful personal version in one sitting, while the paid product mainly wins on polish, sync, importers. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/roam-research.
