Cloudflare Workers has offered JavaScript developers a path to building high-performance, automatically scaling applications since its initial release. Still, getting started with any new technology can feel daunting. Running code at the edge represents a paradigm shift, forcing developers to rethink classic web architecture problems—or discard them entirely. And because the platform can support nearly anything, choosing a first project is often the hardest part.

Built with Workers is a new site designed to answer that question directly: What can I build? It offers a collection of real-world projects, each demonstrating how creators have used the platform, to serve as both inspiration and a practical starting point.

From Graphing Calculators to the Open Web

The motivation for the site comes from a personal experience familiar to many developers. At age 11, the author received a hand-me-down TI-82 graphing calculator on which he learned to write code. The constraints were severe: a non-QWERTY keyboard, a language without functions, and a text editor that frequently lost code. But the most significant challenge was the complete absence of code examples to draw from.

That changed when a friend with a TI-83 Silver Edition showed off a game called Phoenix. It was fast, polished, and entirely different from anything the budding programmer had imagined possible on the hardware. Seeing that game altered his perspective on the platform, sparking the confidence to build similar projects. The ability to view and manipulate another's source code (shared via a physical calculator link cable) kicked off collaboration and iteration with friends.

The web offers a similar kind of openness. Its design makes source code accessible with a simple keyboard command, continuing the tradition of learning by viewing, studying, and adapting what others have built. This philosophy lies at the heart of Built with Workers.

Learning by Building

Every project page on the site includes a section where the creators discuss how their application leverages Cloudflare Workers. Some projects rely on standard use cases like Workers KV, the distributed key-value store, or Workers Sites for edge-based static hosting, while others are entirely written, built, tested, and deployed on the Workers platform. Many of the featured projects are also open source, with direct links to their repositories for closer inspection.

The site itself follows this model—it is one of the open-source projects it features. For developers looking to dive into a new framework or platform, studying such code can remove the friction of a blank slate.

If you have a project that showcases what’s possible with Workers, you can share it by filling out the submission form linked from the site.
