The #1 open-source CRM
Twenty is a modern, open-source CRM alternative to Salesforce—fully customizable, affordable, and powered by the community.
Twenty is open-source and self-hostable, allowing teams to own infrastructure, customize data models, workflows, and UI using TypeScript and standard developer tools. Unlimited custom objects and fields ship with all plans, enabling rapid iteration as business needs evolve.
Twenty provides production-grade building blocks (data model, permissions, authentication, workflow engine), Apps framework for custom extensions, and unlimited workflows. Teams avoid rebuilding infrastructure and compress development cycles from weeks to days.
Twenty includes AI agents with custom skills, MCP server support for Claude/ChatGPT/Cursor, and native AI chat for real-time data updates. Developers can scaffold custom AI skills in TypeScript and deploy to any workspace.
Organization plan ($19/user/month) includes row-level permissions, SAML/OIDC SSO, custom domains, encryption key rotation, and audit logs. Self-hosted deployments provide full infrastructure control for compliance requirements.
Twenty supports CSV import and API-based migration for 50,000+ records, with certified partners handling full migrations. Cloud Pro at $9/user/month or self-hosted free option reduces costs by 90%+ compared to enterprise CRM vendors, while maintaining full customization.
