Penpot

Overview

Penpot is an open source design and prototyping platform that runs in the browser and positions itself as a free, developer friendly alternative to proprietary UI tools. Its defining trait is openness: the software is open source, you can self host it, and it is built on open web standards, so designs are grounded in the same technology developers use to build. That combination made it a favourite among teams that care about ownership, privacy and closing the gap between design and code.

For a studio, the appeal is control. There is no per editor lock in, no vendor deciding your data lives only in their cloud, and a roadmap shaped in the open by a community.

How it works

Penpot works like other modern design tools: you create boards and screens, draw with vector tools, build reusable components, and connect screens into clickable prototypes, all in the browser with real time collaboration. Because it uses SVG as its native format, what a designer produces maps directly onto web friendly output rather than a proprietary file.

Two things stand out. First, design tokens are treated as first class, so colours, spacing and typography can be defined once and shared cleanly with code. Second, you can run Penpot on the vendor cloud or self host it on your own infrastructure, which matters for organisations with strict data or compliance needs. Components and shared libraries support a proper design system, and a Flex and Grid layout model echoes how CSS actually behaves.

Key features

• Open source and free: no per seat licensing, community driven.
• Web based with real time collaboration across any operating system.
• SVG native: designs built on open web standards.
• Design tokens: first class variables shared between design and code.
• Components and libraries: reusable elements for a design system.
• Self hosting: run it on your own servers for full data control.

Use cases

Penpot suits designer and developer collaboration where a shared, standards based source of truth matters. It is a natural fit for open source projects, for privacy conscious organisations that need self hosting, and for teams that dislike per editor pricing. Product and UI teams use it for screen design, component libraries and prototypes, and its token support helps keep a design system in sync with the codebase. For a Webflow oriented studio, it can serve as the visual design layer that translates cleanly into web implementation.

It is also a pragmatic choice for cost sensitive teams that still want modern, collaborative design tooling.

Pros

• Free and open source, with no seat based cost.
• Self hosting for full control over data and privacy.
• Standards based: SVG and CSS friendly layout reduce design to code drift.
• Cross platform: runs in any modern browser.
• Strong tokens and components for design systems.

Cons

Penpot is compelling but honesty about maturity matters. As a younger, community driven project it has a smaller ecosystem: fewer plugins, templates, integrations and tutorials than the dominant incumbent, so you may build workflows yourself. Some advanced features and polish still trail the market leader, and rapid development means occasional rough edges. Self hosting is a real benefit but it is also operational work: someone has to deploy, secure and maintain the instance, which a small team may underestimate. The talent pool is smaller, so most designers will need a short ramp up coming from other tools. Performance on very large, complex files can also lag the most optimised competitors. None of these are dealbreakers, and the project improves quickly, but a team should adopt Penpot for its openness and control with clear eyes about the trade offs rather than expecting feature parity on day one.
