Fei
The OS for building in production — engineering, design, and product together.

Fei (by AutonomyAI) is an AI-native product development platform that unites design, product, and engineering teams in a shared, production-safe environment. It ingests an existing codebase, executes tasks, and automatically delivers code, a live preview, and a pull request for every task. Unlike tools such as Cursor or Lovable, Fei is designed for non-technical users while still producing production-ready code that fits your actual component library and design system.
Fei ingests your codebase and design system, then executes tasks autonomously to produce a live preview, production-ready code, and a pull request — all without requiring an IDE or coding knowledge.
