Why we included this project

Twenty is an open source CRM for teams that want the data model under their own control instead of paying per seat for a closed product. The code-first approach is the main draw: you define objects, fields, and views as code, so a deal or contact schema can be versioned and deployed like the rest of your stack. You can scaffold a new app with the CLI, publish custom objects to your workspace, and self-host on your own infrastructure. The built-in AI hooks let you wire LLM-driven agents into your sales pipeline rather than bolting them on later. For small teams that want a CRM without Salesforce lock-in, this is a practical starting point.
