SuperDesign is an open-source AI product design agent that lives inside your IDE, generating UI mockups, components, and wireframes from natural language prompts. The GitHub repository has earned more than 7,500 stars. The repo preserves the original 2025 open-source IDE extension; the SuperDesign product has since evolved into a web app at superdesign.dev.
SuperDesign was the first open-source design agent built to work where developers already are: inside the editor. From a prompt it produces UI mockups, components, and full design directions you can iterate on conversationally, then implement in code. The team notes in the repository that this open-source extension is kept for history and is no longer actively maintained; development moved to the web product, an AI product design agent that generates UI mockups, components, and full designs from a prompt on an infinite canvas. The design capabilities can also be driven as a skill from coding agents such as Claude Code and Cursor, and a Chrome extension can clone website UIs as starting points. This Tooloso entry links the IDE extension page and documents the open-source origin of the product.
The open-source IDE extension in this repository is free. The current SuperDesign web product is a commercial service with its own plans; check superdesign.dev for up-to-date pricing. This listing’s Freemium label reflects that mix: free open-source origins alongside the paid hosted product.
SuperDesign is for developers and product builders who want design output at coding speed: solo founders mocking up product UI, engineers who prefer prompting over pushing pixels, and teams exploring many UI directions before committing. The archived open-source extension remains a reference for building design agents into editors.
