Logseq vs Heptabase: The Side-by-Side Breakdown
Feature depth separates Logseq from Heptabase more than Writing branding suggests. Logseq pitches an open-source outliner notes app where every bullet is a first-class block; daily journal as the home page, local-first markdown or org-mode files, queries that turn pages into databases. Heptabase pitches a visual notes app where ideas live on whiteboards instead of in a sidebar; tags, sections and journals, sync across desktop and mobile, whiteboards composed of note cards. Watch sync requires self-hosting or a paid add-on on the Logseq side. Heptabase trips on power model takes time to internalize.
