Hosted Browser Agents HOSTED BETA

Browser automation is one of the hardest infrastructure problems in modern AI systems.

While autonomous agents are highly capable of navigating web interfaces, running Playwright, Puppeteer, or Chromium binary dependencies locally introduces massive installation bloat, platform-specific packaging bugs, proxy routing complexity, and fragile sandboxing.

Hosted Browser Infrastructure

Privane solves this by routing automation commands through our secure Hosted Browser Infrastructure via the Managed Tool Gateway. Your local LLM remains the core reasoning coordinator, but the actual Chromium session executes safely in our high-availability cloud cluster (backed by infrastructure partners like PinchTab and Browserbase).

Structured Browser Execution

Traditional web agents scrape screens by sending full page screenshots or massive, raw HTML dumps to the model. This is incredibly slow, eats up thousands of tokens in reasoning context, and leads to frequent hallucinations.

Privane Hosted Browsers expose Structured Browser Execution:

• Accessibility Tree Normalization: We compile the raw DOM into a lightweight accessibility tree containing only interactive items (inputs, buttons, links), reducing context size by up to 90%.
• Normalized Page State: Read form states, page titles, and cookie indices as clean, structured JSON schemas without LLM guesswork.

import { PrivaneTools } from '@privane/tools';
 
const tools = new PrivaneTools({ apiKey: process.env.PRIVANE_API_KEY });
const browser = tools.get("browser");
 
// Launch secure headless cloud browser session
await browser.goto("https://github.com/trending");
 
// Structured extraction with Accessibility Trees
const trendingRepos = await browser.extract({
  schema: {
    repositories: [{ name: "string", description: "string", stars: "number" }]
  }
});

Human-in-the-Loop Safe Guardrails

For high-risk environments, Privane features Human-in-the-Loop Interceptors. You can instruct the gateway to pause execution and request explicit user confirmation before committing critical browser actions:

• Discharging credit card purchases or Stripe checkouts.
• Account registration, deletion, or credential changes.
• Dispatching legal sign-offs or binding submissions.

Technical Advantages

1. Zero Client Bloat: Exclude massive Chromium binary downloads from your local desktop app bundle.
2. Proxy & Captcha Evasion: Built-in residential proxy rotation and automated captcha solver pipelines bypass modern anti-bot guardrails natively.
3. Session Persistence: Keep a cloud browser instance active across multiple local reasoning iterations, preserving logged-in cookie indices seamlessly.
