Twenty CRM

Open-source CRM platform built for flexibility and ownership of customer data. Manages companies, people, deals, tasks, and notes with a modern interface inspired by tools like Notion and Linear. Supports self-hosting or cloud deployment, with a customizable data model, views, and workflows that adapt to evolving business needs.

Twenty is backed by Y Combinator and positions itself as a modern alternative to Salesforce and HubSpot. GPL-licensed so teams own the software instead of renting it, with a community of hundreds of contributors and an open roadmap. Stands out with JSON object fields for flexible data capture, email synchronization with configurable sharing levels, and a command palette for power users.

Key capabilities:

• Customizable objects, fields, and data model without code
• Kanban, table, and list views with filters, sort, and group-by
• Role-based permissions and granular access control
• Workflow automation with triggers and actions
• REST APIs and webhooks for integrations
• Email sync with configurable sharing, and dark mode

Sales and ops teams use it for deal pipelines, contact management, and task follow-ups. Development teams extend it via the NestJS backend and React frontend, self-host for data sovereignty, or integrate with external systems through webhooks and APIs.
