// EDITOR'S TAKE
Odoo is the closest overall, because Keap's value is CRM plus invoicing plus campaigns in one place and Odoo's module set genuinely covers that. If you only need the CRM half, Twenty is far lighter and more pleasant day to day, while EspoCRM is the safer choice when mature workflow automation matters more than modern design.
