What is PenPot.app?

Penpot. an open-source design platform for designers, developers, and product teams that supports UI design, wireframing, interactive prototyping, and responsive rule-based layouts using CSS Grid and Flexbox. Penpot supports design systems with design tokens, components, variants, and shared libraries to maintain a single source of truth across teams. Self-host deployment and enterprise options provide on-premise control and integration with internal tooling. Integrated AI workflows and LLM agents enable code-to-design, design-to-code, and automated design tasks. Open file formats (SVG, HTML, CSS, JSON) and code inspection tools help align design output with production code. Open APIs, plugins, and template libraries support extensibility and developer workflows. Collaboration features such as versioning, shared libraries, and cross-discipline handoff streamline product design and development.
