The picks

3 open source Β· ranked by fit

  1. 01

    SiYuan

    open sourceAGPL-3.0Local or hosted
    46kaug 2026

    Structured blocks, attributes and database views, with less magic and more switches.

    The catch vs Tana

    SiYuan can structure blocks and show database views, but it lacks Tana's fast command-driven supertags and fluid live-search-node workflow.

    The 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

    Logseq

    open sourceAGPL-3.0Local
    44kaug 2026

    An outliner with properties, templates and queries; supertags arrive as several smaller ideas.

    The catch vs Tana

    Logseq has properties, templates, and queries but no single supertag system that instantly turns blocks into typed records with live structured views like Tana.

    Trilium Notes

    open sourceAGPL-3.0+Local or hosted
    37kaug 2026

    Templates, relations and attributes turn notes into records, though the outline is a tree.

    The catch vs Tana

    Trilium's one-primary-parent tree is much more rigid than Tana's block outliner and supertag-driven views for reusing the same structured information.

    Notes, 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

Should I vibe-code or build my own Tana clone from scratch?+

Our build verdict for Tana is KINDA (the core, yes. the polish, no). 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.

SiYuan can structure blocks and show database views, but it lacks Tana's fast command-driven supertags and fluid live-search-node workflow.
