Penpot

Penpot provides a web‑based environment for creating user‑interface designs, interactive prototypes, and design systems. Users can assemble visual components, define layout structures, and link screens to simulate navigation flows. The platform also generates inspection data that developers can use to extract measurements, colors, and CSS values for implementation.

The tool is aimed at designers, product teams, and developers who need a shared space to collaborate on UI work without relying on proprietary software. Because it follows open standards and can be self‑hosted, organizations can run the service on their own infrastructure while maintaining control over data and customization.

What distinguishes Penpot is its focus on openness and practical teamwork. The workspace supports real‑time collaboration, versioning, and handoff features that are built around interoperable formats, allowing contributors to work together regardless of the tools they use elsewhere.
