About

What is Twenty CRM?

Twenty is a modern, open-source CRM built as a developer-first alternative to Salesforce and HubSpot. Designed for the post-SaaS era, it combines a beautiful, opinionated UI with a highly extensible data model and a powerful API — giving teams the familiarity of a polished SaaS CRM with the freedom of open-source ownership. Twenty supports contacts, companies, deals, tasks, notes, and custom objects, and is self-hostable on your own infrastructure for complete control over your sales data.
