Open‑source UI design and prototyping for seamless design‑code collaboration

Penpot is a web‑based, open‑source design platform that combines UI design, prototyping, and code inspection in a single app. It lets designers create flexible layouts, design systems, and interactive flows while automatically generating CSS, SVG, and HTML. Developers can inspect specs and export code directly, eliminating hand‑off friction and fostering real‑time collaboration between design and development teams.
