Tana 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.
Bloques estructurados, atributos y vistas de base de datos, con menos magia y más controles.
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 TanaSiYuan can structure blocks and show database views, but it lacks Tana's fast command-driven supertags and fluid live-search-node workflow.
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

Un outline con propiedades, plantillas y consultas; las supertags llegan como varias ideas más pequeñas.
licenseAGPL-3.0
runson your machine
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 TanaLogseq has properties, templates, and queries but no single supertag system that instantly turns blocks into typed records with live structured views like Tana.
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

Plantillas, relaciones y atributos convierten notas en registros, aunque el esquema es un árbol.
licenseAGPL-3.0+
runsyour machine or their cloud
installDesktop release package, or Docker Compose/image for a server and browser client
dataNotes, hierarchy, attributes, revisions, and most attachments live in a local or server-side SQLite database named document.db; notes can be exported to HTML, Markdown, or OPML
the catch vs TanaTrilium's one-primary-parent tree is much more rigid than Tana's block outliner and supertag-driven views for reusing the same structured information.
setupThe desktop app is straightforward, but cross-device sync and browser access require operating a Trilium server, persisting document.db, and handling backups and upgrades

Tana: 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 $360 a year.
Is there a free alternative to Tana?
Yes: SiYuan, Logseq, Trilium Notes. 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 Tana?
Our verdict is PARCIAL. The visible structured networked notes loop is buildable, but a credible replacement needs more than the first screen. Tana earns its keep through polish, sync, importers, so expect a weekend or multi-day build and a narrower personal scope. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/tana.
