The #1 open-source CRM
Twenty 2.0 is an open-source CRM platform launching as a developer-extensible alternative to Salesforce and HubSpot. The major addition is a new SDK (npm i twenty-sdk) that lets developers define data models, custom objects, workflows, layouts, and widgets in code within their own repos. It ships with built-in AI chat, custom agents, serverless functions, full layout and navigation customization, and remains self-hostable. The goal is to give teams a CRM they fully own and can build on top of, without vendor lock-in.
