What this situation needs

Teams with data-residency requirements or in-house engineers often want a CRM they can host themselves. The products below are listed because their official sites describe them as open source and offer a self-hosted deployment; both also sell a hosted option.

Suitability scores follow a published rubric: 50 points for an open-source licence stated on the official site, 30 for a documented self-hosted install, and 20 for a hosted alternative from the same vendor.
