twenty
An open-source, developer-first CRM designed for AI agents, custom code definitions, and flexible data modeling.
Build, version, and extend your CRM objects, views, and workflows using TypeScript and AI coding agents.
Twenty is a developer-centric CRM designed as an open-source alternative to Salesforce. It allows technical sales and revenue operations teams to define objects, workflows, and UI layouts directly in code. You should use it if you want to pair CRM schema changes with version control and AI coding agents.
What it is
Twenty provides foundational CRM primitives including custom objects, views, and automated workflows. You can define custom entities like deals or contacts using its TypeScript SDK and publish changes straight from your terminal. It also integrates with AI coding tools like Claude Code and Cursor via dedicated agent skills.
Who it's for
It suits technical teams, sales engineers, and developers who need programmatic control over their CRM schema and workflow logic. It is not ideal for non-technical sales managers who require a purely visual builder without developer support. Self-hosters will also need expertise in managing PostgreSQL, Redis, and NestJS infrastructure.

Our honest verdict
What's great
- Allows CRM schema and objects to be version-controlled alongside your main software codebase.
- Includes pre-built skills for AI coding tools like Cursor, Claude Code, and Codex.
- Offers a cloud-hosted option at twenty.com alongside self-hosted Docker deployment.
- Supports programmatic deployment of private apps, views, and logic functions via CLI.
Where it falls short
- Requires technical proficiency in TypeScript and CLI tools to build and extend custom objects.
- Self-hosting demands managing PostgreSQL, Redis, BullMQ, and Node.js infrastructure.
- Absence of a visual, code-free builder for complex logic functions may slow down non-technical users.
Pricing & license
Twenty is open source and free to self-host, though you must pay for your own server hosting, PostgreSQL database, and Redis infrastructure. A cloud-managed option is available at twenty.com with rapid workspace deployment.
