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.
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.
Anchor Browser combines browser sessions with managed authentication and versioned automation tasks. The task product can start from a demonstration or prompt, then expose a reusable workflow.

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.
Anchor Browser: Anchor documents browser profiles alongside an Applications and Identities model. A profile retains state; an identity supplies a managed sign-in connection used with browser sessions.
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.
Anchor Browser: Applications define the target website and authentication behavior. Identities attach managed sign-in to sessions. OmniConnect supplies an embeddable flow for end users to sign in from a product.
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.
Anchor Browser: Automation Tasks produce versioned workflows from a prompt or a recorded demonstration. Test and edit the workflow, then invoke it through the task API. Compare this authoring model with writing a handler directly.
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 |
|---|---|---|---|---|
| Hyperbrowser | 878 ms | 944 ms | 2.03 | 2026-10-18 / 2026-10-17 |
| Anchor Browser | 2433 ms | 2874 ms | 3.22 | 2026-10-18 / 2026-10-17 |

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.
Anchor Browser: Compare the selected browser and task offering using Anchor's current commercial terms. Include network usage and the execution path actually used; a batch API's capacity is not a price quote for that batch.
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.
Anchor Browser: Anchor documents a batch-session API as well as asynchronous session creation. A large batch request is distinct from how quickly every browser becomes ready, so measure the ready state and plan-specific conditions.
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 Anchor Browser when you want managed sign-in and an automation task you can demonstrate, edit and invoke from your application.
Anchor Browser tradeoff: A demonstrated automation task and an arbitrary Python handler are different authoring models. Evaluate how much control you need over the code, dependencies and exact workflow.
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 Anchor Browser 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.
Anchor's demonstration or prompt-authored Automation Tasks and Notte's Python Functions suit different authoring preferences. Both document website-authentication tooling, so a credible recommendation must address the actual login and workflow-editing path.
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.
