Featurebase's free tier is substantive, covering all core modules — feedback forum, roadmaps, changelogs, surveys, and help center — but with hard caps: one feedback board, 100 changelog emails per month, 50 help articles, and three active surveys. Featurebase's paid plans progressively unlock embeddable widgets, custom domains, integrations, and automatic user authentication on Starter; SSO, AI similar feedback suggestions, changelog segmentation, and multi-language support on Growth; and unlimited boards, user segmentation, advanced analytics, API access, and admin roles on Business. G2 reviewers frequently cite integrations and SSO as the features most commonly driving upgrades from the free tier.
