Twenty is a headless customer relationship management framework that enables developers to build, version, and deploy custom business applications using code. By utilizing a declarative approach to data modeling, the platform allows for the definition of custom objects, fields, and complex relationships directly within the source code. This schema-driven architecture automatically generates corresponding REST and GraphQL APIs, ensuring that data structures and interface components remain synchronized across development and production environments.
The platform distinguishes itself through a modular, code-first development experience that avoids proprietary lock-in. Developers can extend core functionality by packaging custom server-side logic, automated workflows, and React-based user interface components. These extensions execute within sandboxed environments, providing secure, isolated runtime performance while maintaining granular control over data access and system resources.
Beyond its core modeling capabilities, the platform includes a comprehensive suite of tools for business automation, integration, and team collaboration. It supports event-driven workflows that trigger actions based on record changes, scheduled tasks, or external webhooks, alongside AI-powered agents for data processing and conversational interaction. The system also provides robust developer tooling, including command-line scaffolding, containerized deployment support, and integrated CI/CD pipelines to manage the entire application lifecycle.
The project is designed for self-hosting or cloud deployment, offering full data ownership and infrastructure control. Documentation and installation are facilitated through standard command-line interfaces, allowing teams to initialize projects, manage dependencies, and sync code changes in real time.
