Krateable is a small project with a big love for open-source software. We create thoughtfully designed merchandise inspired by programming languages, developer tools, and tech stacks that power modern computing. From classic scientific software to today’s most popular frameworks, our goal is to celebrate the projects that make technology possible.

We’re an independent brand, not affiliated with or endorsed by the organizations whose logos or projects are featured. Each item is made for developers, researchers, and programmers who want to show their support for open source. A portion of every sale goes to the foundations and communities that maintain and grow the software we all rely on.

Open-source is more than code. It is a global community of contributors. That is why part of every sale supports the organizations and developer communities that maintain and improve the software we rely on every day.

Show your love for open-source software with Krateable’s developer tees, hoodies, and tech gifts, and help keep these projects thriving.

Please note: All items are printed on demand, which helps reduce waste and overproduction. Because of this, returns and exchanges aren’t accepted unless the product arrives damaged or defective. Please review the size guide carefully before placing your order.
