Subframe is an AI‑native design tool that lets designers build interfaces using the same reusable components that power production code. The platform generates pixel‑perfect, framework‑agnostic front‑end code that designers can export instantly and engineers can edit directly in their IDEs, eliminating the manual handoff between mockups and implementation. All generated code is owned by the user and the AI operates only on the team’s own component library, ensuring consistency with existing styling conventions.

Problem
Design teams often create visual mockups that must be manually translated into front‑end code, a process that is time‑consuming, error‑prone, and creates a disconnect between design and production components.
Solution
Subframe offers an AI‑native design environment that lets designers build interfaces directly with the same reusable components used in production. The tool generates pixel‑perfect, clean front‑end code without relying on generic AI models, ensuring the output matches the team’s codebase and styling conventions. Designers work visually with drag‑and‑drop, while the platform handles styling and component integration, producing code that can be immediately edited in any IDE. Because the generated code is owned outright by the user, engineers can focus on business logic rather than re‑implementing designs.
Target Audience
Primary customers are product design teams and front‑end engineering groups building web applications who need a reliable bridge between design and production code.
Features
