An open-source, developer-first toolkit for building highly customized CRM solutions using React, Supabase, and Shadcn UI.
Atomic CRM is an open-source, developer-first toolkit designed for companies that need a professional CRM without the limitations or costs of proprietary SaaS platforms. Built by Marmelab (the creators of react-admin), it serves as a high-performance foundation that developers can fully customize, extend, and self-host to ensure total data sovereignty. Key Capabilities: Modern Tech Stack: It is built on a cutting-edge stack including React, TypeScript, Tailwind CSS, and Supabase (PostgreSQL), utilizing the shadcn-admin-kit for a polished, responsive UI. Complete Data Ownership: Unlike traditional CRMs, Atomic CRM allows businesses to host their own data on Supabase or their own infrastructure, making it an ideal choice for European companies concerned with GDPR and data privacy. Essential CRM Features: Out of the box, it includes robust tools for contact management, task tracking, note-taking, and a visual Kanban-style deals pipeline to monitor sales progress. Advanced Productivity: It supports enterprise-grade features such as Single Sign-On (SSO) (via Google, Azure, or Auth0), "Email to Note" integration, and an MCP Server that allows users to query and update CRM data using AI assistants in plain language. Unlimited Scalability: Because it is open-source and self-hosted, there are no per-user licensing fees or artificial limits on the number of leads, contacts, or deals you can manage. Why Choose Atomic CRM? Atomic CRM bridges the gap between basic spreadsheets and bloated enterprise software. It provides a "production-ready" starting point that can be deployed in minutes, yet offers deep, code-level flexibility, from theming and custom pages to an extensible data model, allowing the software to adapt perfectly to a company's specific business logic.
