Web development has advanced in leaps and bounds in the last decade, but front-end testing has not. Testing sucks. It’s the part that every developer dreads.

It’s often harder to write a passing test than an actual feature.

We want to spend our time building cool things, and we need tools that match how we build modern applications.

Therefore we built a revolutionary new testing tool from the ground up. We have created a product that we love and actually use ourselves.

Our team is highly experienced and passionate about solving problems. We’re lucky enough to have some of the best minds in the industry.

Being open source, Cypress is evolving faster and better than if we worked on it alone.

Now developers can ship their software faster and more consistently, with confidence.

We believe testing needs a lot of love, and we are here to foster a tool, a service, and a community that can teach and benefit everyone.
