It shows how users sign in via a normal browser, then use the launcher to open a full-screen micro-browser that combines a looping video background with a sandboxed web experience. The runtime provides security and isolation by granting micro-browsers only user-approved permissions such as network access, media embedding, and storage. The presenter also demonstrates custom dimensions like a Notion and Midjourney launcher, a MatrixGPT themed ChatGPT variant, and developer-focused setups with paired terminals and a Monaco editor with a running web contents preview.
