Penpot is an open-source design and prototyping platform built for teams that value collaboration, openness, and freedom from vendor lock-in. It offers a browser-based interface for creating UI/UX designs, wireframes, and interactive prototypes – similar in function to tools like Figma or Sketch, but with a transparent, self-hostable architecture. Developed by Kaleidos, Penpot is designed to serve designers and developers equally, supporting open standards like SVG and focusing on interoperability, community-driven development, and ethical software principles.
