Page Analysis

Analyze and understand web page content, structure, and interactive elements using Python code execution. Produces a comprehensive breakdown of what is on the page and how it is organized.

All code runs via openbrowser-ai -c. The daemon starts automatically and persists variables across calls. All browser functions are async -- use await.

The CLI daemon also persists cookies and login state in ~/.config/openbrowser/profiles/daemon/storage_state.json, so authenticated sessions can be reused across later runs.

Setup

Before running, verify openbrowser-ai is installed:

openbrowser-ai --help

If not found, install:

# macOS/Linux
curl -fsSL https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.sh | sh

# Windows (PowerShell)
irm https://raw.githubusercontent.com/billy-enrizky/openbrowser-ai/main/install.ps1 | iex

Workflow

Step 1 -- Navigate and get overview

openbrowser-ai -c - <<'EOF'
await navigate("https://example.com")
state = await browser.get_browser_state_summary()
print(f"Title: {state.title}")
print(f"URL: {state.url}")
print(f"Interactive elements: {len(state.dom_state.selector_map)}")
print(f"Tabs: {len(state.tabs)}")
EOF

Step 2 -- Extract page metadata

openbrowser-ai -c - <<'EOF'
meta = await evaluate("""
(function(){
  return {
    title: document.title,
    description: document.querySelector("meta[name='description']")?.content,
    canonical: document.querySelector("link[rel='canonical']")?.href,
    ogTitle: document.querySelector("meta[property='og:title']")?.content,
    ogImage: document.querySelector("meta[property='og:image']")?.content,
    lang: document.documentElement.lang,
    charset: document.characterSet
  };
})()
""")

import json
print(json.dumps(meta, indent=2))
EOF

Step 3 -- Detect frameworks and technologies

openbrowser-ai -c - <<'EOF'
tech = await evaluate("""
(function(){
  const t = [];
  if (window.__NEXT_DATA__) t.push("Next.js");
  if (window.__NUXT__) t.push("Nuxt.js");
  if (document.querySelector("[data-reactroot]") || document.querySelector("#__next")) t.push("React");
  if (document.querySelector("[ng-version]")) t.push("Angular");
  if (window.jQuery) t.push("jQuery");
  if (window.Vue) t.push("Vue.js");
  if (document.querySelector("[data-svelte]")) t.push("Svelte");
  return t;
})()
""")
print(f"Technologies detected: {tech}")
EOF
