The Verdict
Capacities is built for knowledge workers and researchers, with a focus on object-types and daily-notes. Roam Research targets researchers and writers and leads with bidirectional-links and block-references.
On pricing, Capacities is the clear winner for budget-conscious users — starting at $9.99/mo compared to $15/mo for Roam Research. That $5.01/mo difference adds up quickly for growing teams.
Capacities has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Roam Research requires a paid subscription from day one.
Capacities edges out on user ratings (4.4 vs 4.1). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Roam Research offers broader built-in capabilities (7 features vs 6), while Capacities takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for knowledge workers, researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Capacities has a slight overall edge — but if bidirectional links surface unexpected connections matters most to you, Roam Research may still be the right call.
