AI agents don't live in the browser. They live in the operating system.

Most people still think of AI agents as chatbots that can browse the web. Sophisticated chatbots, sure. But fundamentally: you talk to them in a browser, they respond, maybe they click some things. That mental model is wrong — and it's limiting what people build. The agents doing real work in 2026 aren't living in browser tabs. They're running as daemons. Web-First Agents vs OS-Native Agents Web-first: Lives in a browser or cloud sandbox. Interacts through HTTP, REST APIs, web UIs. Stateless between sessions. Controlled by whoever hosts the cloud. Constrained to what the web can see. OS-native: Runs as a local process. Has access to the filesystem, terminal, process control, system state. Persistent across reboots. You own the execution environment. Can interact with anything the machine can touch. The difference isn't cosmetic. It's the difference between an employee who can only email you vs one who can walk around the office, open files, run scripts, and talk to other processes. Whe
