Open-source alternatives
to HubSpot.

The closest open-source alternatives to HubSpot are Twenty, SuiteCRM, Frappe CRM, and EspoCRM. Twenty matches HubSpot's modern UX with AI features; SuiteCRM covers enterprise sales processes; Frappe CRM is clean and fast-growing; EspoCRM deploys in minutes. All four are self-hostable with no per-seat fees.

Teams leave HubSpot when per-seat pricing explodes with headcount and when contact data must stay in-region. Open-source CRMs remove the seat tax entirely and keep every record on your servers. The tradeoff is implementation: HubSpot works out of the box, while self-hosted CRMs need setup and maintenance.
