About

Fei is an AI-powered engineering agent that operates directly within your codebase, intelligently reusing components and adhering to your design system and coding standards to generate production-ready backend code that often passes review on the first try. It ingests inputs such as Figma designs, Jira tickets, screenshots, or plain text and transforms them into backend-ready code within minutes, significantly accelerating development cycles without compromising quality or security. Fei acts as an autonomous teammate rather than just a coding assistant, enabling scalable output without adding headcount and ensuring that generated code aligns with existing infrastructure and conventions. This level of integration and contextual awareness means teams can ship real products, not prototypes, with confidence, speed, and consistency.
