The Verdict
Heptabase is built for researchers and students, with a focus on whiteboards and card-system. Obsidian targets researchers and writers and leads with markdown and backlinks.
On pricing, Obsidian is the clear winner for budget-conscious users — starting at $4/mo compared to $11.99/mo for Heptabase. That $7.99/mo difference adds up quickly for growing teams.
Obsidian has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Heptabase requires a paid subscription from day one.
Both tools are a solid fit for researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
