Penpot

Penpot is a browser-based design and prototyping platform built for teams working on digital products. It covers the full design process, from early wireframes through polished UI, interactive prototypes, and developer handoff, without requiring separate tools for each stage. It's self-hostable, so teams with strict data requirements can run it on their own infrastructure.

The core workflow connects designers and developers more directly than most tools. Instead of exporting assets and writing specs separately, Penpot generates 1:1 CSS, HTML, SVG, and JSON directly from the design. What you see in the canvas is what developers get in code, which cuts down on the back-and-forth that usually happens during implementation.

Key capabilities include:

• Design Systems with reusable components and design tokens, giving teams a shared source of truth that stays in sync across projects
• Flexible layouts using grid and auto-layout tools suited for responsive UI design
• Prototyping with interactive flows built directly on the canvas, no separate prototyping mode required
• AI workflows with multi-directional agentic support, letting teams connect any LLM or agent into their design process
• Code inspect that surfaces accurate CSS and HTML values without manual annotation

Penpot is a practical alternative to Sketch or Adobe XD for teams that want full control over their tooling. Because it's open source and web-native, there's no per-seat licensing tied to a vendor's pricing decisions, and it works across operating systems without a desktop install.

It suits product teams where designers and engineers work closely together, particularly those building design systems at scale or looking to bring AI tooling into their existing design process.
