Heptabase’s whiteboard-plus-cards model is genuinely one of the better ways to make sense of long-form thinking. The problem is the price. At around $12 a month billed monthly, or $9 a month annually, Heptabase costs more than Notion, Obsidian Sync, and most of its peers combined. Mobile access exists but lags the desktop app, and the higher AI tiers push the bill past $50 a month.
We tested seven Heptabase alternatives that keep the visual mapping, spatial thinking, and card-on-whiteboard approach without the subscription surprise. Every pick works on desktop across Windows, macOS, and Linux (or at least two of the three), and every pick handles the core workflow: you dump ideas onto a canvas, arrange them, connect them, and let the structure teach you what you actually think.

Why people leave Heptabase
Heptabase does one thing extremely well: it makes visual thinkers feel at home. The reasons people still shop for something else are usually about price, ownership, or platform reach.
The Pro plan runs $8.99 a month annually, and the higher tiers with more AI credits push that closer to $18 or $54. Compared to Obsidian (free, with a $4 sync add-on) or AFFiNE (free, with an optional $8 tier), that gap is hard to justify unless the whiteboards are the whole reason you took notes in the first place.
Users on Reddit and Hacker News consistently mention two other pain points. First, data ownership: Heptabase stores your work in a proprietary format, and export options are limited to markdown snippets that lose the spatial layout. Second, AI credit ceilings: the base plan includes 100 AI credits a month, which sounds generous until you use the summarization or auto-connection features for a real project.
The mobile app also lags. Sync works, but building on a phone is a chore, and the offline story is rough compared to Obsidian’s fully local vault.
The alternatives
Obsidian with Canvas — Best for people who want a real vault behind the whiteboard
Obsidian is the default answer for anyone leaving a proprietary note tool. The Canvas core plugin gives you a whiteboard that pulls in existing markdown notes as cards, alongside images, PDFs, and embedded search queries. Because everything is a local file, the spatial layout is just JSON you can commit to git.
Where it falls short: Canvas is not as polished as Heptabase’s whiteboard. Zoom, snapping, and card resize behave in ways that will feel primitive if you spent a year in Heptabase.
Pricing:
- Free: Full desktop app, unlimited vaults, all core plugins including Canvas.
- Paid: Sync at $4 a month or $48 a year for encrypted vault sync. Publish at $8 a month.
- vs Heptabase: Roughly a tenth of the price if you add Sync, or free if you use iCloud, Syncthing, or git.
Migrating from Heptabase: Export cards as markdown, drop them into a vault folder, and rebuild whiteboards in Canvas by dragging the notes in. There is no automated importer, but because Obsidian is text-first the migration is a one-time chore, not a recurring lock-in.

Bottom line: Best pick if you already care about markdown, plain text, and long-term ownership. Second best if you don’t yet, and want to start.
Logseq — Best for outliner users who also want whiteboards
Logseq started as a block-based outliner in the Roam Research lineage and grew a whiteboards feature that mixes tiddler-style blocks with a canvas. The killer combination is that the same block can appear on multiple whiteboards and inside your daily journal, which Heptabase does not really do.
Where it falls short: The whiteboards feature is still labeled beta and lags the outliner side. Performance dips on very large graphs, and the desktop app has occasional sync hiccups if you point it at Dropbox or iCloud.
Pricing:
- Free: Everything. The desktop app is open source under AGPL.
- Paid: Logseq Sync is a paid tier at around $5 a month when it exits beta; you can skip it and use your own file sync.
- vs Heptabase: Free vs $9 to $12 a month.
Migrating from Heptabase: Export Heptabase cards as markdown, import them into Logseq’s pages, and rebuild the visual layer. Logseq’s whiteboards do not import Heptabase whiteboards directly.
Download: Logseq on GitHub
Bottom line: Best pick for open-source purists who want an outliner backbone. Skip if you dislike outliner-style bullet blocks.
Scrintal — Best for academic research workflows
Scrintal is the closest visual match to Heptabase. Same card-on-canvas model, similar linking, similar backlinks. Where it pulls ahead is PDF handling: highlights become cards automatically, citations track back to the source page, and the reading pane sits next to the canvas.
Where it falls short: No native mobile app. Real-time collaboration is available but slower than Heptabase’s on large canvases.
Pricing:
- Free: 14-day trial.
- Paid: $9.99 a month billed monthly, $7.99 a month billed annually.
- vs Heptabase: Slightly cheaper, especially annually.
Migrating from Heptabase: Export markdown cards and rebuild boards. Scrintal has an unofficial JSON import helper that some users have shared, but no first-party importer.
Download: Scrintal official site
Bottom line: Best pick for researchers, PhD students, and analysts who annotate PDFs constantly. Skip if you don’t work with source documents.
Milanote — Best for creative moodboards and project mapping
Milanote takes a different angle: instead of a knowledge graph, it treats boards as design surfaces. You drop images, videos, links, and short notes onto a canvas and arrange them by feel. It is the app that Heptabase power users usually pick when they realize their real workflow is closer to art direction than research.
Where it falls short: Backlinks and bi-directional links are shallow. Search is fine but not graph-aware. Not great for building a permanent second brain.
Pricing:
- Free: 100 notes across all boards.
- Paid: $12.50 a month billed monthly, $9.99 a month annually.
- vs Heptabase: Similar price. Milanote wins on visual polish, loses on knowledge structure.
Migrating from Heptabase: Manual. Rebuild each board by dragging your existing cards in.
Download: Milanote official site
Bottom line: Best pick for designers, filmmakers, brand strategists, and anyone whose boards are 60% images. Skip for research or personal knowledge management.
AFFiNE — Best for one tool that covers docs, boards, and tables
AFFiNE is an open-source workspace that blends Notion-style docs, Miro-style whiteboards, and airtable-style databases into one edgeless canvas. The “Edgeless” mode is close to Heptabase’s whiteboard, and every document can flip between doc mode and board mode.
Where it falls short: AFFiNE is newer than the other picks and the sync layer has hit bugs in the last year. Local-first works, but multi-device syncing needs discipline.
Pricing:
- Free: Full desktop app, self-host option, and cloud sync up to 10 GB.
- Paid: Pro at $8 a month for higher limits.
- vs Heptabase: Free tier alone matches Heptabase’s core.
Migrating from Heptabase: No direct import. AFFiNE reads standard markdown, so a markdown export from Heptabase drops in, but you lose spatial layout.
Download: AFFiNE on GitHub
Bottom line: Best pick if you want to consolidate Notion, Heptabase, and Airtable into one app. Skip if you want a mature product with no rough edges.
Kinopio — Best for freeform thinking with almost no structure
Kinopio is the app to reach for when Heptabase feels too heavy. The interface is one canvas with cards you type into, connect with lines, and drag around. There is no database, no properties panel, no vault sidebar. Just spaces and cards.
Where it falls short: No PDF handling, no rich media beyond images, no mobile app worth using yet.
Pricing:
- Free: 100 cards per space, limited spaces.
- Paid: $6 a month or $60 a year for unlimited.
- vs Heptabase: Half the price and a tenth of the complexity.
Migrating from Heptabase: Manual. Card text moves via copy-paste; layout does not.
Download: Kinopio official site
Bottom line: Best pick when the point of your canvas is thinking out loud, not filing knowledge. Skip if you need structure.
Excalidraw — Best for diagramming that lives inside your existing tools
Excalidraw is a hand-drawn-style diagramming tool with an infinite canvas. Excalidraw is not a knowledge base, but the desktop app and the Obsidian plugin turn it into a whiteboard that lives alongside whatever notes you already keep. Every diagram exports to PNG, SVG, or markdown-embeddable code.
Where it falls short: No built-in card system, no backlinks, no database. Excalidraw diagrams and Heptabase whiteboards solve different problems.
Pricing:
- Free: Full open-source app forever.
- Paid: Excalidraw+ at $6 a month for cloud saves and team libraries.
- vs Heptabase: Free vs $9 to $12 a month, if you can accept the narrower feature set.
Migrating from Heptabase: Not a straight swap. Use Excalidraw as a companion to Obsidian or Logseq rather than a Heptabase replacement.
Download: Excalidraw on GitHub
Bottom line: Best pick as an add-on to whatever note tool you already run. Skip as a standalone Heptabase replacement.
How to choose
Pick Obsidian with Canvas if you want the safest long-term bet. Your notes stay yours in markdown, the app has a decade-long roadmap, and the whiteboard side is good enough for 80% of Heptabase use cases.
Pick Scrintal if your real workflow is PDF-heavy academic or market research. The citation tracking alone earns the subscription back.
Pick Milanote if you moodboard, storyboard, or plan campaigns and the visual polish matters more than the graph.
Pick AFFiNE if you want to collapse Notion, Airtable, and Heptabase into one open-source workspace, and you can tolerate the roadmap being younger.
Pick Kinopio if Heptabase felt too structured and you just want a fast, quiet canvas.
Stay on Heptabase if the AI-augmented linking is doing real work for you and mobile is not a blocker. The card model is still the most refined in this category.
FAQ
Is there a free Heptabase alternative?
Yes. Obsidian with the Canvas plugin, Logseq, AFFiNE, and Excalidraw are all free for personal use. Obsidian and Logseq are the closest fits for people who want a whiteboard that connects to their notes.
Can I import my Heptabase cards into Obsidian?
Partially. Heptabase exports cards as markdown, which drops into an Obsidian vault as regular notes. What you lose is the whiteboard layout. Rebuilding the boards in Obsidian Canvas is a one-time manual task.
What is the cheapest Heptabase alternative that still has whiteboards?
Excalidraw+ at $6 a month is the cheapest paid option with a real cloud sync. Kinopio at $6 a month is the same price with a stronger card model. If free is fine, use Obsidian with Canvas or Logseq.
Which apps work like Heptabase on macOS and Linux?
Obsidian, Logseq, and AFFiNE ship native apps for Windows, macOS, and Linux. Scrintal and Milanote are cross-platform via Electron. Kinopio is a web app that installs as a PWA.
Is Notion a Heptabase alternative?
Not really. Notion is a database and docs tool with a limited whiteboard integration through partners. If you want a canvas-first tool, look at the picks above instead.
