Chromium version

Cloudflare Browser Rendering currently uses Chromium version 124.0.6367.257.

Browser Rendering allows developers to programmatically control and interact with a headless browser instance and create automation flows for their applications and products. Once configured, the service provides access to a WebSocket endpoint that speaks the DevTools Protocol ↗. This protocol is what allows Cloudflare to instrument a Chromium instance running in the Cloudflare global network.

If you want to programmatically confirm the version in your environment, you can retrieve it using either Puppeteer or Playwright.

Puppeteer

import puppeteer from "@cloudflare/puppeteer";

async fetch(request, env) {
  const browser = await puppeteer.launch(env.MYBROWSER);
  const version = await browser.version();
  console.log("Chromium version:", version);
  await browser.close();
})().catch(console.error);

Playwright

const { chromium } = require("playwright");

(async () => {
  const browser = await chromium.launch();
  const version = await browser.version();
  console.log("Chromium version:", version);
  await browser.close();
})().catch(console.error);
