What does Fastgen do?

Fastgen is a visual development platform that lets you build scalable backends, APIs, and automated workflows through a drag-and-drop interface. Instead of writing code and managing servers, you can create REST endpoints, set up authentication rules, connect to databases, and integrate with third-party services visually. The platform handles deployment and hosting automatically, eliminating the need for DevOps configuration.

The tool provides a complete environment for building and debugging applications. You can test APIs with custom headers and parameters, view detailed execution logs for each action, and fix issues directly in the visual editor. Fastgen includes features like variables, conditional logic, code injection for custom Node.js or Python logic, environment variables for secrets, and an AI-assisted SQL copilot to help write database queries.

Fastgen is designed for developers and product builders who want to create backend systems quickly without infrastructure management. It works well for startups building MVPs, teams automating business processes, or developers creating API integrations between services. The platform's visual approach and built-in hosting make it particularly useful for projects that need to move fast without sacrificing reliability.
