// EDITOR'S TAKE
Twenty is the closest in both design and philosophy, with custom objects and a records-first interface that clearly took cues from Attio, though its reporting is still shallow. EspoCRM offers far deeper entity customisation and automation if you can live with a dated admin UI, and atomic-crm only makes sense if you plan to fork it and build the CRM into your own React app.
