Our verdict

Last verified Jun 12, 2026

Solid for clubs/associations with good member relationship tracking, fully free, actively maintained (v5.0.10, May 2026, 459 GitHub stars); scores lower on CRM feature depth (no deals/pipeline/fundraising), minimal integration breadth, and narrow segment fit — appropriate only for membership-management use cases.
