Browser agent

Also known as: web agent · web-browsing agent

Agents

A browser agent operates a web browser: it reads rendered pages, clicks, fills forms, and navigates to complete web-based tasks.

  • Works with sites that have no API.
  • Operates on what a human would see.
  • Faster and safer than full computer use, but still GUI-bound.

When it earns its keep: if a site has an API, use the API. Browser agents are for the long tail of web apps that only expose a UI.
