LogseqOpen sourcedesktopmobileOne-click installation

Cards, block links and whiteboards for sense-making, with rougher furniture.

LicenseAGPL-3.0

PlatformsOn your machine or in the cloud

InstallationDownload the desktop/mobile release or use the hosted web app; no server is required for a local graph

DataClassic file graphs are folders of Markdown or Org-mode files plus Logseq configuration/cache files and can be synced with a file service; the newer DB graph stores the graph in a local SQLite database, while optional Logseq Sync/RTC sends graph data to Logseq's service

Limitations compared to HeptabaseIts links and whiteboards are powerful, but whiteboard polish, mobile experience, and performance are rougher, while the newer database path still carries beta risk.

SetupStable local installation is simple, but the visually stronger DB graph/RTC path is still beta or alpha and explicitly carries data-loss warnings; free cross-device file-graph sync requires choosing and safely operating a third-party file-sync method

AFFiNEFreedesktopmobilewebself-hostedOne-click installation

Documents and an infinite canvas in one local-first app, without the research tax.

LicenseMIT AND MPL-2.0

PlatformsOn your machine or in the cloud

InstallationUse AFFiNE Cloud or install the desktop app; self-hosted collaboration uses the official Docker Compose stack with AFFiNE, PostgreSQL, and Redis

ModelsAFFiNE AI supports bring-your-own-key routes for OpenAI, Anthropic, Gemini, and FAL; local storage is available in the desktop app, while self-host AI is configured server-side

DataA local-only desktop workspace stays on that device; AFFiNE Cloud stores it in AFFiNE's service, while self-hosted workspaces use PostgreSQL for structured data, mounted blob storage for uploads, Redis for cache, and local configuration files

Limitations compared to HeptabaseIt offers documents and an infinite canvas, but its canvas is less specialized for research cards, spatial synthesis, and guided sense-making than Heptabase's.

SetupThe desktop app is straightforward, but free self-hosted sync and collaboration require Docker, PostgreSQL, Redis, persistent volumes, configuration, migrations, backups, and a correctly exposed server URL

Why people still pay for Heptabase

Heptabase: People pay for a writing surface they trust for years, plus migration tools, sync, and tiny interaction details that disappear into habit. If those points do not matter to you, the options above could save $108 per year.
