John O'Nolan, Co-founder and CEO at Ghost, shared at Penpot Fest 2025 his view on how creative constraints and self-imposed limitations can actually be a good way to narrow down your options and sparkle creativity.

Ghost, a fully open-source, independent publishing platform, emerged from one and only creative constraint: stay true to its mission and to its users, without growing into a wealthy project only serving its shareholders profit.

Penpot is the free open-source design tool for Design & Code collaboration.

Penpot is ideal for product design: UI designs, prototypes, wireframes, mockups, webs, apps, and much more.

Penpot allows a true collaboration and no handoff drama between designers and developers thanks to features like CSS Grid Layout, Flex Layout and Code Inspect.

Designers get a professional, intuitive, powerful design tool with ground-breaking responsive layouts, design systems at scale. While developers get a design tool that expresses as code and provides ready-to-use code to develop faster.

Penpot is the only one that can be web-based or self-hosted. The app works with open standards (SVG and CSS) avoiding vendor lock-in. Also, it enables teams the flexibility and control in their designs, thanks to the API and webhooks available.
