About Browser Harness

What the tool does and who it's for

Browser Harness is a developer-focused tool designed to bridge the gap between Large Language Models (LLMs) and web browsers. By adding just a few lines of code, developers can implement a self-healing browser 'harness' that grants an LLM full control over Chrome via the Chrome DevTools Protocol (CDP). This allows AI agents to interact with websites naturally—clicking, scrolling, and filling out forms—while maintaining resilience against UI changes. Because it is self-healing, the tool automatically adapts to changes in the Document Object Model (DOM), significantly reducing the need for manual updates or recoding of automation scripts.
