About Atomic CRM

Atomic CRM, published by Marmelab, is an open-source customer relationship manager built with React, shadcn admin components and Supabase. It is designed as a codebase you fork and customize, giving teams a working CRM they can adapt rather than a closed product, and an online demo is available to try.

Core features include organized contacts, tasks with reminders, notes, a Kanban board for managing deals through a sales pipeline, activity history, and import and export of contacts. Emails can be captured by copying the CRM address so conversations are saved as notes. Login is supported through Google, Azure, Keycloak and Auth0, an API allows integration with other systems, and custom fields, themes and components can be changed.

The project is written in TypeScript and licensed under MIT. It runs locally with Node, Make and Docker, which start a Vite front end and a local Supabase instance, and the codebase can be kept up to date through a shadcn registry. It suits small businesses and developers who want a self-managed CRM they can modify.
