Twenty is a CRM built to be modified. Custom objects and fields, composable data models, views and no-code workflows, with a TypeScript apps framework for anything the interface cannot express, available self-hosted or as managed cloud. An MCP server connects Claude, ChatGPT and Cursor to the data directly.
Open source is the answer to the specific complaint everyone has about CRM. The data is the most valuable thing a company owns, the schema never fits the business without work, and the vendor charges for both facts; self-hosting removes the leverage. Migration tooling from Salesforce and HubSpot exists because that is who the buyer is leaving.
Cloud Pro is $9 per user a month billed yearly, Organization $19 with SSO and row-level permissions, both with a 30-day trial, and the source is on GitHub. Self-hosting a CRM means owning backups and uptime for the system sales depends on, a younger project has a smaller integration ecosystem than the incumbents, and customisability is work before it is a benefit.
