Free, open-source design workspace for Mac and Windows that turns your coding agent into a design engine — prototypes, sites, slides, dashboards, images and HTML video, all on one brand system, stored locally.
OpenDesign, by Powerformer, is an open-source desktop app for macOS and Windows that turns coding agents into a design engine. Point it at any of 21+ agents (Claude Code, Codex, Cursor, Gemini and more), pick or import a design system, and describe what you need: it produces prototypes, websites, slide decks, dashboards, marketing images and HTML video that stay on-brand, with a live sandbox preview you can edit. It also converts designs, screenshots and Figma files to code. Everything is local-first and stored on your machine. The app is free under Apache-2.0, with 93.5K+ GitHub stars and 400+ contributors; the only cost is the API usage of whichever model provider you choose.
