What is Twenty?
Twenty is an open-source customer relationship management (CRM) platform that gives technical teams the building blocks for a custom CRM: objects, views, workflows and AI agents, all of which can be extended as code. Workspaces cover companies, people, opportunities, tasks and notes, and administrators can add custom objects, fields, views and no-code workflows from Settings without writing code. Records can be shown as tables, Kanban boards or calendars, and Google and Microsoft email and calendar accounts sync so emails and meetings are logged automatically.
Developers extend Twenty with its Apps framework. An app defines custom objects, server-side logic functions, React components that render inside the Twenty UI, AI skills and agents, views and navigation in TypeScript, and is published to a workspace with the Twenty CLI. Each workspace exposes REST and GraphQL APIs generated from its own schema, so a new custom object immediately gets the same endpoints as built-in objects. Webhooks and a native MCP server let assistants such as Claude, ChatGPT and Cursor read and write CRM data.
Twenty runs on a managed cloud or on your own infrastructure with Docker Compose, on a stack of TypeScript, NestJS, PostgreSQL, Redis and React. The repository is mostly licensed under the AGPLv3, with an added permission for applications built on its interfaces; files marked with an Enterprise licence comment are under a commercial licence, and the app toolkit and UI library are MIT licensed. Self-hosting the open source core is free. Cloud plans start at $9 per user per month billed yearly, after a 30-day trial.
