Overview

Overview

Twenty is a modern, self-hosted CRM designed for teams that want full control over their customer data and user experience. Built with TypeScript, NestJS and React, it provides a responsive web interface where users can switch between kanban, table, and grid views, apply filters, sorting and grouping, and tailor layouts to their workflows.

Capabilities & Deployment

The platform lets you define custom objects and fields, set granular role-based permissions, and automate processes through a built-in workflow engine that supports triggers and actions such as sending emails or creating calendar events. Because it runs on PostgreSQL and Redis, you can deploy it on-premises, in a private cloud, or via Docker containers on any major cloud provider. The active community contributes plugins, documentation, and support through Discord, making it a viable alternative to proprietary CRMs.

Considerations

  • Self‑hosting requires infrastructure expertise
