Hyperbrowser vs Cloudflare Browser Run

The decision

Start with the product contracts for saved browser state, credential handling, website sign-in, code execution. Different labels do not establish different functionality; compare the implementation and conditions behind each one.

Hyperbrowser provides cloud browser sessions with profile persistence and browser credential fill. Its broader catalog also has sandboxes and other APIs; this comparison concerns the browser and the code or authentication attached to it.

Cloudflare Browser Run provides headless browser sessions through CDP and browser code deployed in Workers. This comparison concerns sessions and their execution model, rather than the separate Quick Actions APIs.

What survives a session

Hyperbrowser: Profiles save browser user-data-directory state, including cookies, local storage, session storage and cache. A fresh session has a fresh directory unless a profile is attached and its save behavior is selected.

Cloudflare Browser Run: Cloudflare documents reuse of browser sessions and a Durable Objects integration. Keeping a session alive is different from exporting a portable authenticated profile; design the required state store explicitly.

Website login

Hyperbrowser: Credential fill refers to stored secrets or vaults by name and fills selected inputs. The documented flow supports credentials and one-time codes; saved profiles address browser state after sign-in.

Cloudflare Browser Run: Use browser code to implement the website's sign-in flow and retain the necessary session state. The reviewed overview does not establish a managed website connection that checks sign-in readiness before a workflow starts.

Where the code runs

Hyperbrowser: Action Caching records a HyperAgent action sequence for deterministic replay. The broader platform also offers sandbox compute. Check how a handler is deployed, invoked and versioned before choosing the execution path.

Cloudflare Browser Run: Deploy browser automation within a Cloudflare Worker or connect to Browser Run from an external process over CDP. Workers provide the execution layer; compare their runtime and deployment model separately from browser access.

Published browser measurements

These are the latest provider runs in the saved BrowserArena snapshot checked on October 18, 2026. Dates and runner environments can differ. A lifecycle test opens, connects, navigates and releases a browser; the throughput test runs a separate browser action sequence. Neither measures managed authentication or deployed Function reliability.

Use these observations to choose what to test in your application. An account-configuration failure, an incompatible page action and a timed-out navigation require different interpretations. BrowserArena is maintained by Notte and publishes its source and methodology.

Pricing model

Hyperbrowser: The reviewed pricing page lists $0.10 per browser-hour and $10 per GB of proxy traffic. Credits acquired through subscriptions and direct purchases have different refresh or expiry behavior.

Cloudflare Browser Run: Price browser usage and the Worker execution components required by the workload. The Browser Run pricing page, rather than a single browser-hour estimate, defines included allowances and applicable limits.

Capacity and limits

Hyperbrowser: Session concurrency and configuration are account-dependent. Use the session API's supported settings and public limits rather than assuming that available sandbox capacity is browser concurrency.

Cloudflare Browser Run: Browser Run has its own limits and pricing alongside Workers. Account browser capacity, session creation limits and the Worker execution budget constrain different parts of a workflow.

Which approach fits?

Choose Hyperbrowser when you need existing Playwright, Puppeteer or Selenium code to use a managed browser with saved state and named credentials.

Hyperbrowser tradeoff: Browser sessions, sandbox execution and action caching are separate surfaces. A cached action sequence is not the same deployment contract as an independently versioned browser Function.

Choose Cloudflare Browser Run when you already deploy Workers and want browser automation within that application's execution and scheduling model.

Cloudflare Browser Run tradeoff: A Worker and a browser session have separate resource and lifecycle constraints. Confirm the chosen browser library and binding path instead of assuming an unchanged local browser script will deploy directly.

Check the browser connection

Install playwright-core in your application and provision a session through the provider's documented creation flow. Run this smoke test from the intended controller region with the returned CDP endpoint. It checks connection and navigation, not login, rendering parity or a complete business workflow.

Keep browser connection URLs on your backend. After the test, release the owned session through the provider's API. Product-specific lifecycle APIs and profile identifiers are not portable between providers.

import { chromium } from "playwright-core";

// Provision the owned browser using the provider's documented session API.
// Keep the connection URL in your backend's secret environment.
const endpoint = process.env.BROWSER_CDP_URL;
if (!endpoint) throw new Error("Set BROWSER_CDP_URL for an owned session");

const browser = await chromium.connectOverCDP(endpoint);
try {
  const context = browser.contexts()[0] ?? await browser.newContext();
  const page = context.pages()[0] ?? await context.newPage();
  await page.goto("https://example.com", { waitUntil: "domcontentloaded" });
  if ((await page.title()) !== "Example Domain") {
    throw new Error("The browser did not reach the expected page");
  }
  console.log({ connected: true, expectedPage: true });
} finally {
  await browser.close();
  // Release the owned session with the provider's documented API as well.
  // A disconnected socket alone is not a portable session-cleanup contract.
}

Before you switch

Keep the same target workflow when evaluating both products. Separate infrastructure facts from measurements and test the required account state, action sequence and artifacts. A successful connection test does not establish that a long or authenticated task will complete.

Use the focused guides for Hyperbrowser and Cloudflare Browser Run below when the deciding requirement is pricing, persistence or code execution. Provider-owned resources such as session IDs, profiles and managed connections need a new mapping during migration.

When Notte belongs on this shortlist

Hyperbrowser's profiles, credential tools and Action Caching deserve separate evaluation. A recorded action sequence and a deployed Python handler have different maintenance contracts, so decide which one your team will edit after the website changes.

Cloudflare can be an economical architectural choice when Workers and the surrounding scheduling already exist in your application. Notte is worth evaluating when a browser, deployed Python handler and authentication workflow should share a product rather than a Workers composition.

Notte: Create an owned browser session, connect Playwright or Puppeteer over CDP, and stop the session when the work finishes. Browser lifecycle management remains necessary even when the control socket disconnects.

Consider this third option when its documented mechanism addresses a requirement left open by the two providers above. A working configuration on either original provider can still be the better choice; compare the task and ownership cost before switching.
