Sigmaos

Sigmaos is a modern web browser designed to streamline how you work, research, and browse online. Its primary purpose is to replace traditional tab-heavy browsing with a structured, workspace-based environment that makes it easier to focus, organize information, and move between tasks. Sigmaos aims to provide a faster, distraction-reduced browsing experience tailored for people who work extensively on the web.

Sigmaos organizes your browsing into “spaces,” allowing you to group pages by project, client, or topic instead of juggling dozens of unrelated tabs. It includes built-in split-screen browsing so you can view multiple pages side by side, which is particularly useful for research, writing, or comparing information. The browser offers keyboard-first navigation and quick commands to open, search, and switch between pages without leaving the keyboard. Sigmaos also syncs your work across devices, and its session management makes it easy to pick up where you left off without losing context.
