Penpot
Design and code beautiful, interactive interfaces — the open-source design tool for design and code collaboration.
Penpot is the first open-source design and prototyping platform built for cross-domain collaboration between designers and developers. Unlike proprietary tools, Penpot is built entirely on web standards using SVG, CSS, and HTML natively — meaning designs closely reflect what browsers actually render. It supports Flexbox and CSS Grid layouts directly in the design canvas, allowing designers to create responsive layouts that translate directly to frontend code. Real-time multiplayer collaboration enables teams to work together on designs simultaneously, with commenting and feedback workflows built in. With self-hosted and cloud options, an open API, and a growing plugin ecosystem, Penpot offers full creative freedom without vendor lock-in. Its commitment to open standards makes it uniquely positioned at the intersection of design and development.
