Browser Agent
Drive websites through a structured DOM/accessibility tree and a small action set — faster and more reliable than pixel-level screen control.
Intent & Description
🎯 Intent
Give an agent web access without raw HTML soup or brittle pixel clicking.
📋 Context
You need an agent that fills forms, scrapes competitive data, navigates multi-page checkouts, or researches across many sites — all with no clean API. Raw HTML is too noisy; pixel-level Computer Use is too slow and fragile for routine web work.
💡 Solution
A Playwright-backed library exposes structured page state (numbered interactive elements, accessibility tree) and a compact action set (click, type, scroll, navigate). The agent reasons over the structured state and emits actions; the library executes them.
Real-world Use Case
- The agent must operate websites and a structured DOM/accessibility tree is available.
- Raw HTML is too noisy and pixel-level screen control is too slow or brittle for the target.
- A small action vocabulary (click, type, scroll, navigate) covers the workflow.

📌 TL;DR
Skip raw HTML and pixel clicking. Give your agent a structured DOM view and a small action set — it’ll handle the web faster and with fewer surprises.
Advantages
- Faster and more reliable than pixel-driven Computer Use for web tasks.
- Web-specific abstractions like ‘fill form’ compose naturally and read clearly in traces.
Disadvantages
- Still struggles with heavily dynamic JS-rendered apps where the accessibility tree is a mess.
- Anti-bot measures and CAPTCHAs break the loop and are hard to recover from gracefully.
