Cards, block links and whiteboards for sense-making, with rougher furniture.
licenseAGPL-3.0
runsyour machine or their cloud
installDownload 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
the catch vs 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
