The decision
Start with the product contracts for credential handling, website sign-in, code execution, scheduled execution. Different labels do not establish different functionality; compare the implementation and conditions behind each one.
Steel is a browser API with managed cloud and self-hosted deployment paths. Its current documentation covers persistent profiles, a credential API, session replay and agent observability.
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.

What survives a session
Steel: The Profiles API documents reusable browser context, cookies, extensions, credentials and browser settings. Steel also documents lighter auth-context reuse, which should not be confused with a complete profile.
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.
Website login
Steel: Steel's Credentials API stores credentials for users or agents. Its cookbook demonstrates using stored credentials with Playwright, while profiles and auth contexts preserve signed-in browser state.
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.
Where the code runs
Steel: The reviewed browser documentation establishes sessions, profiles and credentials. It does not establish a hosted Python handler with deployment and invocation APIs. An external worker can control a Steel browser; price and operate that worker separately.
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.
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.
| Provider | Lifecycle median | Lifecycle P95 | Actions / second | Run dates |
|---|---|---|---|---|
| Steel | 1496 ms | 1950 ms | 3.54 | 2026-10-18 / 2026-10-17 |
| Hyperbrowser | 878 ms | 944 ms | 2.03 | 2026-10-18 / 2026-10-17 |

Pricing model
Steel: Hosted browser plans and a self-hosted browser have different cost structures. For self-hosting, include the worker, compute, networking, storage and operations rather than assigning the open-source code a zero operating cost.
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.
Capacity and limits
Steel: Steel's pricing and limits page describes hosted account entitlements. For a self-hosted deployment, capacity depends on the resources and orchestration you operate as well as the browser process.
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.
Which approach fits?
Choose Steel when you want browser infrastructure that can fit a self-hosted deployment, with profiles and credentials available through browser-focused APIs.
Steel tradeoff: Hosted and self-hosted Steel are different operating choices. A cloud feature's documentation does not establish identical packaging, retention or operational support in a self-hosted installation.
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.
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 Steel and Hyperbrowser 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
Steel's managed and self-hosted choices make infrastructure ownership a concrete deciding factor. Keep that option on the shortlist when operating the browser is intentional; evaluate Notte when owning fewer execution and authentication components is the actual goal.
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.
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.
