Arc is a web browser, but more importantly, it’s everything you care about, all in one place. Despite the ways our internet use has evolved, the browser has remained relatively unchanged. While all of our other software tools are changing for the better—with more collaborative features, flexible interfaces, and powerful functionality—the browser largely still does what it did twenty-five years ago. What’s more, we blame ourselves for the browser’s shortcomings. When our browser has an overwhelming number of tabs, we call ourselves inefficient; when we get distracted online, we tell ourselves we need more discipline; when we can’t find a url, we think we’re disorganized. Why does the browser get a free pass? That’s why we’re building a new browser, which we call Arc, because we believe browsers can do so much more to empower us. We’re imagining a browser that can think as quickly as we do, take work off of our plates, and pull our creativity forward.

OMEGA is an ultra-lightweight native macOS web browser engineered to provide maximum privacy, minimal footprint, and fast performance by leveraging the WebKit engine already built into Apple devices rather than bundling a heavy browser engine of its own. At around 3.6 MB on disk and launching in under a second, it prioritizes privacy by blocking third-party trackers, fingerprinting scripts, and ad-tech endpoints at the network level so browsing behavior isn’t profiled or shared with data brokers, and it includes aggressive features such as YouTube ad neutralization, Fortress Mode for strict security and HTTPS upgrades, and anti-fingerprinting techniques that inject slight noise to make persistent identification harder. OMEGA’s Amnesia Mode lets you browse in RAM so session data disappears when you quit, and the Nuke Button lets you wipe cookies, cache, history, and site data across selectable time ranges.
