Browserless Alternative

The No-Code-Required Alternative to Browserless

Browserless hosts a headless browser for your Puppeteer/Playwright scripts. AlterLab is the whole pipeline — you send a URL, AlterLab decides how to render it and returns clean data. No browser automation code required.

  • One API call replaces a full Puppeteer/Playwright script
  • Automatic tier selection — no manual browser session configuration
  • Structured JSON output, not a raw browser connection you have to script

Why Teams Switch from Browserless

1

No browser automation code to write or maintain

Browserless gives you a remote Chrome instance you connect to and script with Puppeteer or Playwright. AlterLab skips that layer entirely — send a URL and an extraction schema, get structured data back. Nothing to write, deploy, or debug when a target site's DOM changes.

2

Automatic rendering tier, not a fixed browser session

AlterLab decides per-request whether a static fetch, a lightweight render, or a full browser session is needed, and only pays the corresponding cost. Browserless always spins up a full browser session regardless of whether the target page needs one.

3

Built-in extraction, not just a browser connection

Browserless returns whatever your script tells it to (screenshots, PDFs, raw page content) — you own all the parsing logic. AlterLab returns structured JSON, markdown, or HTML directly, with parsing handled server-side.

Migration Takes Minutes

Estimated time: 20 minutes to remove browser automation code

Browserless (Puppeteer)
const browser = await puppeteer.connect({
  browserWSEndpoint: "wss://chrome.browserless.io?token=YOUR_TOKEN"
});
const page = await browser.newPage();
await page.goto("https://example.com/product");
const title = await page.$eval("h1", el => el.textContent);
await browser.close();

Frequently Asked Questions

Do I still need Puppeteer or Playwright with AlterLab?

No. AlterLab replaces the need to write and maintain your own browser automation scripts. You send a URL and describe the data you want; AlterLab handles rendering and returns structured output. Browserless requires you to write and host the Puppeteer/Playwright logic yourself.

Is AlterLab cheaper than Browserless for full-browser rendering?

It depends on volume and page complexity, but the key difference is AlterLab only uses a full browser session when a page actually needs one — simpler pages resolve at a cheaper tier automatically. Browserless bills unit-time for every session your script opens, regardless of whether the target needed a full browser.
