Twenty

Twenty is a CRM built for teams that have outgrown generic tools but don't want to spend months building something from scratch. It gives developers a production-grade foundation covering data modeling, permissions, authentication, and workflow automation, while letting non-technical users customize objects, fields, views, and workflows directly from Settings without writing a line of code.

The core idea is composability. Instead of bending your business to fit a fixed data model, you define the objects and relationships that match how your team actually works. A company running carbon credits, agricultural products, and industrial systems can run all three from a single modular setup. A team migrating from Salesforce or HubSpot can import data via CSV or API and have a working CRM in days.

For developers, Twenty ships an Apps framework that lets you scaffold extensions in TypeScript and deploy custom objects, server-side logic functions, React components that render inside Twenty's UI, AI agents and skills, custom views, and navigation items. Every Cloud workspace includes a native MCP server, so AI assistants like Claude or Cursor can read and write CRM data in natural language.

Key capabilities include:

• Custom data model: Define any object, field type, or relation without touching a schema file manually
• No-code workflows: Build automations from Settings, no developer required
• AI coding support: Works with Cursor, Claude, and ChatGPT for rapid iteration on custom extensions
• Real-time updates: Live data across all views with an AI chat assistant built in
• Self-hosted or managed cloud: Full infrastructure ownership or a zero-ops cloud option at $9/user/month
• API-first: REST and GraphQL APIs, plus MCP for AI tool integration
• Role-based permissions: Row-level access control available on the Organization plan

The UI is clean and Notion-like, with keyboard shortcuts, smart command menus, and kanban or table views for opportunities. Teams that have moved from proprietary CRMs report cost reductions of over 90% after switching to a self-hosted instance. Unlike other open source CRM options, Twenty is designed to scale from a startup's first pipeline to an enterprise-grade operational backbone.
