System requirements

  • Google Chrome with Manifest V3 extension support
  • An Anthropic Messages–compatible API key (Anthropic, DeepSeek, GLM, …)
  • Permission to load unpacked extensions (Developer mode)

Before you run it

Browsergent is experimental. It exposes everything the extension can access to the agent — page content, cookies, auth headers — so we can learn the capability boundary. Always review its actions and avoid running it on accounts where that access is unacceptable. There is no built-in spend limit; the agent will keep calling the model until the task ends or you stop it.
