Stack

A spatial browser that replaces traditional tabs with side‑by‑side cards, allowing users to arrange web applications in a visual flow. The interface emphasizes a clean, uncluttered layout designed to keep attention on the content while minimizing distractions. Navigation relies on keyboard shortcuts and a “fly mode” that lets users move quickly between cards, and the system supports multiple profiles for separating personal and work contexts.

The browser integrates existing Chrome extensions, so users can keep their usual tools within the same environment. It also offers a multiplayer mode where participants can share files, messages, and links, collaborating in a Figma‑like space. Additional features include ad‑ and tracker‑blocking, colorful realms for visual customization, and a personal assistant that guides interactions.

Developed as an open‑source project and owned by its community, the software targets people who need to manage many web‑based tools on a single screen—such as remote workers, designers, and anyone seeking a more organized online workspace. Its stable release focuses on speed, simplicity, and customizable organization without relying on traditional tab structures.
