On pricing, Obsidian is the clear winner for budget-conscious users — starting at $4/mo compared to $15/mo for Roam Research. That $11/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. Roam Research requires a paid subscription from day one.

Both tools are a solid fit for researchers, writers, knowledge workers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
