Atomic CRM is an open-source, full-featured customer relationship management (CRM) application built with React and Supabase. It provides core sales CRM functionality while remaining developer-friendly for building tailored CRM experiences.

Key Features

  • Contact management with searchable, centralized records
  • Deal pipeline management with a Kanban-style board
  • Tasks, reminders, and note-taking linked to customers and deals
  • Email capture workflow to store communications as notes
  • Import/export tools for moving contact data in and out
  • Access control with support for external identity providers (via OIDC)
  • Activity history and aggregated activity logs
  • API-first backend provided by Supabase (Postgres + REST)
  • Developer-centric customization: custom fields, theming, and replaceable UI components

Use Cases

  • Small teams needing a self-managed CRM for contacts, deals, and follow-ups
  • Agencies or SaaS teams building a customized CRM on top of a ready-made base
  • Internal sales ops tools requiring auditability and integrations via an API

Limitations and Considerations

  • Customization is primarily code-driven (no full graphical customization UI)
  • Production setup depends on correctly configuring Supabase services (auth, database, storage)

Atomic CRM fits teams that want a modern CRM foundation with a React UI and a Postgres-backed backend. It is especially suitable when you need to extend the data model and UI components to match a specific workflow.
