Stack is a spatial web browser that organizes the web as cards on a canvas rather than rows of tabs, built for keyboard-first, distraction-free browsing. Features include Fly Mode for fast navigation, multiple user profiles, customizable visual themes called realms, Chrome extension support, and privacy-focused browsing without ads or trackers, with multiplayer collaboration planned. Stack is a consumer desktop application and does not currently publish a public API, developer platform, or SDK. Backed by 500 Global and community-funded via WeFunder.
