Overview

Learn about Hyperbrowser Sessions

In Hyperbrowser, a Session is simply a dedicated, cloud-based browser instance that’s yours to direct. It’s like opening a fresh, private browser window—only this one lives in the cloud and is fully controllable through code. Each Session keeps its own cookies, storage, and browsing context, so you can run your tasks without mixing them up.

With our Sessions API, you can spin up these browser environments whenever you need them, configure them with optional parameters, and close them down when you’re done. Higher level endpoints like scrape and crawl also utilize sessions internally to handle their tasks.

Connect with your favorite browser automation libraries

Puppeteer

Connect with Puppeteer to automate browser actions via a websocket connection

Playwright

Connect with Playwright to automate browser actions via a websocket connection

Check out our API Reference to see the Sessions API in more detail

Usage

Starting a session is pretty simple, you can either startup a session directly by connecting to our websocket endpoint with your preferred automation tool like Playwright or Puppeteer, or you can create a session via the Sessions API.

Simple Connect

With this approach, you can startup a session with all default configurations set by just changing one line.

Node

Puppeteer

const browser = await puppeteer.connect({
    browserWSEndpoint: `wss://connect.hyperbrowser.ai?apiKey=${process.env.HYPERBROWSER_API_KEY}`,
});

Playwright

const browser = await chromium.connectOverCDP(
    `wss://connect.hyperbrowser.ai?apiKey=${process.env.HYPERBROWSER_API_KEY}`
);

Python

Puppeteer

browser = await pyppeteer.connect(
    browserWSEndpoint=f"wss://connect.hyperbrowser.ai?apiKey={os.getenv('HYPERBROWSER_API_KEY')}"
)

Playwright

with sync_playwright() as p:
        browser = p.chromium.connect_over_cdp(
            f"wss://connect.hyperbrowser.ai?apiKey={os.getenv('HYPERBROWSER_API_KEY')}"
        )

The simple connect approach doesn't support setting parameters. Use the Session API below for customizing session parameters, such as proxies, web recordings, or extensions.

Connect with Sessions API

With this approach, you have more control over your sessions with additional features or updated configurations.

Node

Puppeteer

import { connect } from "puppeteer-core";
import { Hyperbrowser } from "@hyperbrowser/sdk"
import { config } from "dotenv";

config();

const client = new Hyperbrowser({
  apiKey: process.env.HYPERBROWSER_API_KEY,
});

const main = async () => {
  const session = await client.sessions.create({
    solveCaptchas: true,
    useStealth: true,
    useProxy: true,
  });
  const browser = await connect({
    browserWSEndpoint: session.wsEndpoint,
  });

  const [page] = await browser.pages();

  // Navigate to a website
  console.log("Navigating to Hacker News...");
  await page.goto("https://news.ycombinator.com/");
  const pageTitle = await page.title();
  console.log("Page 1:", pageTitle);
  await page.evaluate(() => {
    console.log("Page 1:", document.title);
  });

  // Clean up
  await page.close();
  await browser.close();
  await client.sessions.stop(session.id);
};

main();

Playwright

import { chromium } from "playwright-core";
import { Hyperbrowser } from "@hyperbrowser/sdk";
import { config } from "dotenv";

config();

const client = new Hyperbrowser({
  apiKey: process.env.HYPERBROWSER_API_KEY,
});

const main = async () => {
  const session = await client.sessions.create({
    solveCaptchas: true,
    useStealth: true,
    useProxy: true,
  });

  const browser = await chromium.connectOverCDP(session.wsEndpoint);

  const context = await browser.newContext();
  const page = await context.newPage();

  // Navigate to a website
  console.log("Navigating to Hacker News...");
  await page.goto("https://news.ycombinator.com/");
  const pageTitle = await page.title();
  console.log("Page 1:", pageTitle);
  await page.evaluate(() => {
    console.log("Page 1:", document.title);
  });

  // Clean up
  await page.close();
  await context.close();
  await browser.close();
  await client.sessions.stop(session.id);
};

main();

Python

    async with async_playwright() as p:

Hyperbrowser's CAPTCHA solving and Proxy features require being on a PAID plan.
