Penpot

Penpot is a web-based design and prototyping platform for creating UI/UX designs, interactive prototypes, and design systems collaboratively. It is built around open standards (notably SVG) and aims to provide a workflow that works well for both designers and developers.

Key Features

• Real-time multiplayer collaboration with comments and shared workspaces
• SVG-first vector design workflow with shapes, text, fills/strokes, and constraints
• Interactive prototyping (screens, flows, links, transitions) for clickable previews
• Design systems support via reusable components and libraries
• Developer-focused handoff features (inspect properties, measurements, and assets)
• Import/export oriented around standard formats (notably SVG) for interoperability
• Role-based team organization features for collaborative projects

Use Cases

• Designing and iterating product UI screens with multiple stakeholders in one file
• Building and maintaining a reusable component library/design system
• Creating clickable prototypes for user testing and stakeholder reviews

Limitations and Considerations

• Feature parity with some established proprietary design suites may vary by workflow (e.g., advanced plugin ecosystems and certain specialized tooling).

Penpot is a strong option for teams that need a collaborative UI design tool with a standards-oriented approach and practical developer handoff. It is particularly suitable when SVG interoperability and transparent, inspectable design artifacts are important.
