Penpot

Penpot is an open-source design platform for teams that build digital products. It runs in the browser, and it can also be installed on your own servers.

Penpot lets you draw screens, build responsive layouts and organize them with design systems. Its file format is open and uses standards such as SVG, CSS and JSON. Teams edit the same file together, and AI agents can connect to the tool through an MCP server.

• Responsive layouts with CSS Grid and Flex
• Shared components and design tokens
• Wireframes and interactive prototypes
• Code inspection in CSS, HTML and SVG
• MCP server for connecting AI agents

Penpot fits product design teams and developers who want an open tool they can inspect and control. It also suits organizations that need to keep design files on their own servers. Solo designers can use it for wireframes and prototypes.

You can sign up for free to use the hosted version. The code is open source under the Mozilla Public License 2.0, so you can also self-host it. Penpot Enterprise is offered for businesses that need extra support.
