This is one of those questions that has come up every few months internally at Cloudflare for years. Unsurprisingly, it’s the kind that triggers long threads with multiple reasons and persuasive arguments on why we should do it. The browser is obviously the most important software we use every day on our computers; it’s arguably the operating system of the Internet. We’re a company on a mission to help build a better Internet — who wouldn’t want to take on the challenge of building a new browser? But we never quite found the balance between the technical difficulty of such an endeavour and the unique problems we’d be solving by doing it. And so, the idea was shelved, over and over again. Until now. Something magical happened: we reached a tipping point where a series of powerful technical advancements in our Developer Platform became a reality, while the advent of AI agents and the demand for a new kind of browser became critical at the same time.
