Atomic CRM
A self-hosted Business, CRM & Commerce app you can run on your own server.
Atomic CRM is an open, self-hosted business application — you install it on your own hardware and keep full control of your data. It is a practical pick for homelab users and teams who prefer owning their tools over renting them.
Development happens in the open on GitHub; the repository has collected 1.2K stars so far. Repository activity was last recorded on Sep 10, 2026, and the project is classed as actively maintained in our snapshot.
Before you switch
Business software touches money and customer data, so run it in parallel with your current system for one full cycle before switching. Verify imports (contacts, products, invoices), user permissions, and backup exports. Most mature projects have active communities that have documented the migration path.
Like every project listed on SelfHosted, Atomic CRM is developed in the open — you can read the code, follow development, and even contribute. Check the system requirements and the project’s own documentation linked on this page before installing.
