SigmaOS: The new home for your internet 🏡

The new home for your internet 🏡

SigmaOS is a new type of browser designed for founders, researchers, and content creators to make you better and faster at working on the web. You work 7+ hours a day on the web. Buried in a sea of 100+ tabs and 10+ web-apps 🤯, you constantly lose context for why you did what you did, and are always one click away from being distracted. We took apart the browser for you, and rebuilt a new experience from the ground-up, for the FASTEST and most PRODUCTIVE work. ⚡
