Best overall
Twenty
Twenty is a modern open source CRM that feels built this decade, and self-hosting it costs nothing under AGPL-3.0. You get contacts, companies, custom objects, a Kanban pipeline, workflows, and an API, with no per-seat fee and no cap on records or users (as of July 2026). It is the closest thing to owning your CRM outright.
Twenty wins because it is the rare free CRM with no asterisk on ownership: the core is AGPL-3.0, so you self-host it for nothing, add as many users and contacts as you like, and never pay a per-seat fee (as of July 2026). The catch is real and worth stating up front. Free means self-hosting, so you need Docker, a PostgreSQL database, and someone comfortable running updates and backups, because the hosted cloud has no free tier, only a 30-day trial before $9 per user per month. If nobody on your team can run a container, a hosted free plan like Zoho CRM is the more honest pick, but for a team that owns its own stack, Twenty gives you the most CRM for zero dollars.
