Open-source alternatives to SuiteCRM

SuiteCRM is itself already a free, open-source CRM — it was forked from the last open-source release of SugarCRM after SugarCRM went proprietary, and it's maintained by SalesAgility. So if you landed here comparing SuiteCRM to other tools, the question usually isn't "how do I go open source" but "which open-source CRM fits better" — for a simpler, more modern self-hosted option than SuiteCRM's SugarCRM-derived codebase, EspoCRM is a common alternative.
