Logseq vs Heptabase

Logseq is a free, open-source, local-first outliner with flashcards and a privacy-first ethos; Heptabase is a visual learning tool where notes are cards you arrange and connect on infinite whiteboards. Here’s how they compare on pricing, platforms, linking, search, capture and collaboration — and how to decide between them.

What is Logseq?

Logseq is the open-source counterpart to Roam: an outliner built on bidirectional links and daily notes, but storing everything as local Markdown (or Org-mode) files on your device. It’s free, AGPL-licensed, and adds flashcards with spaced repetition, PDF annotation, queries, whiteboards and a plugin ecosystem. Sync is available end-to-end encrypted, or you can roll your own with Git or Syncthing.

The project is mid-transition: alongside the classic Markdown version, a rebuilt “DB version” backed by a local database entered public beta in July 2026, bringing real properties and Tana-style structured tags plus more reliable sync. That rewrite consumed several years of development attention, so the classic version evolved slowly — but the foundation of free, local, open-source outlining has kept a devoted community.

What is Heptabase?

Heptabase is for people who think spatially. Notes are cards; understanding happens by laying them out on infinite whiteboards, drawing connections, grouping into sections and mindmaps, and annotating PDFs alongside. It’s a deliberate take on learning deeply — less “capture everything” and more “make sense of what you’re studying” — and nothing else in this list matches its canvas experience.

Cards support Markdown, backlinks, tags with table views, and journals, so it still functions as a complete note system off the whiteboard. It runs on desktop, web and mobile with offline support and cloud sync. There’s no free plan (7-day trial); 2026 pricing is AI-credit-tiered — Pro at $8.99/month (annual) with Premium tiers above it for heavier AI use.

Logseq vs Heptabase at a glance

Pricing and features as of mid-2026 — check each product’s site for current details.

Where Logseq shines

• Free and open source (AGPL) with local-first storage — the strongest ownership story among outliners.
• Built-in spaced-repetition flashcards and PDF annotation, no plugins needed.
• Block references, queries and whiteboards cover most of Roam’s power features.
• The new DB version adds structured properties and tags with trustworthy sync.

Worth knowing: No real-time collaboration — it’s a single-player tool. The MD-to-DB transition splits the product; some features (like whiteboards) are temporarily missing from the DB beta. Polish and mobile experience trail the paid competition, and web capture relies on community tooling.

Where Heptabase shines

• The best whiteboard-native note experience available — cards, sections, mindmaps and connections feel built-in, not bolted on.
• PDF annotation on the same canvas as your notes suits deep study workflows.
• Tags double as tables, giving light database views over cards.
• Solid offline support with sync across desktop, web and mobile.

Worth knowing: No free plan — only a 7-day trial. Collaboration is limited to shared whiteboards; it’s primarily single-player. Spatial organization is the point — if you don’t think in maps, the canvas is overhead rather than insight.

Which should you choose?

Choose Logseq if:

• You want Roam-style outlining without the subscription, as open-source software.
• Local files and end-to-end-encrypted sync are non-negotiable.
• You want flashcards built into the same tool as your notes.

Choose Heptabase if:

• You learn by arranging ideas spatially and drawing the connections yourself.
• You study from PDFs and want annotation living next to your notes.
• A visual overview of a topic matters more to you than fast capture.

A third option: Dexi

If what you actually want is one searchable place for notes, bookmarks, newsletters and RSS — with tags, @mentions and [[wiki links]] that organize themselves as you write, semantic search that finds ideas even when the words don’t match, and an MCP server so Claude and other AI assistants can work with your notes directly — take a look at Dexi. It’s free for up to 1,000 notes, with no app to install.
