Lightpanda Browser
The headless browser built from scratch for AI agents and automation.
Not a Chromium fork. Not a WebKit patch. A new browser, written in Zig.

Example Puppeteer script
```js
import puppeteer from 'puppeteer-core';
// use browserWSEndpoint to pass the Lightpanda's CDP server address.
const browser = await puppeteer.connect({
browserWSEndpoint: "ws://127.0.0.1:9222",
});
// The rest of your script remains the same.
const context = await browser.createBrowserContext();
const frame = await context.newPage();
// Dump all the links from the frame.
await frame.goto('https://demo-browser.lightpanda.io/amiibo/', {waitUntil: "networkidle0"});
const links = await frame.evaluate(() => {
return Array.from(document.querySelectorAll('a')).map(row => {
return row.getAttribute('href');
});
});
console.log(links);
await frame.close();
await context.close();
await browser.disconnect();
```
### Agent mode
`lightpanda agent` lets you drive the browser with a native agent. Describe what
you want in plain English or with slash commands, and it controls the browser:
navigating pages, clicking through flows, filling forms, extracting structured
data. Think of it as a robot you're directing to use the web, more than a
chatbot you're having a conversation with.
Because the agent runs inside the same process as the browser, every tool call
is a direct operation and you retain Lightpanda's speed and memory advantage.
The output of an agent session is a
[PandaScript](https://lightpanda.io/docs/usage/pandascript): vanilla JavaScript
with a small set of native browser primitives built directly into Lightpanda.
Run `/save` to export one from your current session, then replay it with
`lightpanda agent
