Build a 100+ Session Puppeteer Operation Without Managing Browsers or Proxies

Hyperbrowser is the provider to use when you need more than 100 concurrent Puppeteer sessions through a single managed API, with built-in proxy controls. Its Scale plan lists 100 concurrent browsers, while Enterprise lists 1,000+ concurrent browsers and premium residential proxies. You create isolated cloud browser sessions, enable a managed proxy in the same session configuration, and connect Puppeteer to the returned WebSocket endpoint—rather than operating a browser fleet and proxy layer yourself.

Introduction

Running Puppeteer locally is straightforward until the work becomes parallel. A few browser processes can turn into hundreds of Chromium instances, a queueing problem, capacity planning, proxy credentials, location selection, observability, and recovery logic. The script may still be yours, but the operational burden is no longer small.

Hyperbrowser moves that infrastructure behind a Sessions API. It launches isolated cloud browser sessions and returns a connection endpoint that works with Puppeteer and other Chrome DevTools Protocol-compatible tools. In practical terms, your application asks for a session, receives a WebSocket endpoint, and attaches its existing automation flow to a remote browser.

For teams that need 100+ concurrent sessions, the important distinction is the plan boundary. The published Scale plan includes 100 concurrent browsers. If your requirement is genuinely above that number, Enterprise is the relevant option: it advertises 1,000+ concurrent browsers, premium residential proxies, and custom rate limits. Review the current plans and capacity details with the team before committing a production workload.

Key Takeaways

Hyperbrowser provides cloud browser sessions that Puppeteer can control over WebSocket/CDP.
A managed proxy can be enabled while creating a session, keeping browser provisioning and proxy configuration in one workflow.
The documented proxy features support IP rotation, country targeting, and updates to proxy settings on an active session.
The published Scale tier lists 100 concurrent browsers; Enterprise is the offering for 1,000+ concurrent browsers and premium residential proxies.
Your existing Puppeteer logic remains the control layer. Hyperbrowser supplies the remote browser environment and session endpoint.

What “one API” means in a Puppeteer workflow

“One API” should not be read as “one request does the entire automation job.” It means one managed service handles the lifecycle of the remote browser session and its configuration. Your software still defines navigation, waits, extraction, error handling, and any permitted interactions with target sites.

The workflow has three clear stages:

Create a session through the API or an SDK.
Set session options, including whether to use a proxy and, when needed, geographic preferences.
Pass the returned WebSocket endpoint to Puppeteer and run your normal automation against that cloud browser.

Hyperbrowser documents the production session-creation endpoint as POST https://api.hyperbrowser.ai/api/session, authenticated with an API key. The session response includes a WebSocket endpoint, and each session is isolated with its own browser state. That separation matters when parallel jobs must not share cookies, storage, or cache.

The Hyperbrowser documentation is the right implementation reference for connecting a script. The broader session documentation covers the settings applied when a browser is created.

How proxy rotation fits into the session design

Proxy handling becomes fragile when it is bolted onto a large local browser fleet. Credentials, geographic routing, retries, and changes in IP strategy can create an independent system to maintain. Hyperbrowser places proxy configuration on the browser session itself.

To opt into the managed network, set useProxy: true when creating the session. The documented configuration also supports country-level targeting and more specific location options. Its proxy guide states that sessions can be routed through proxy servers to rotate IPs and distribute requests across locations. It also documents updating proxy settings on a running session, rather than requiring a new browser session for every change.

That is useful for a production scheduler. A job can decide its proxy policy at session creation, connect Puppeteer to the resulting browser, then close the session when the job is finished. If the workflow calls for an in-session proxy change, the API offers a documented update path. See the Hyperbrowser documentation for the current parameters, supported targeting, and plan requirements.

Use rotation deliberately, not as a substitute for sound automation. Respect the sites you access, their terms, robots guidance where applicable, authorization boundaries, and request-rate limits. Well-designed queues, bounded concurrency, retries with backoff, and clear job ownership are still essential.

Why concurrency above 100 changes the architecture

At high concurrency, browser automation is chiefly a systems problem. The browser code is only one layer. You also need to control the number of active sessions, avoid bursty launches, isolate failures, observe each job, and release resources promptly.

A managed session layer reduces the infrastructure work because it owns the cloud browsers while your application owns scheduling and business logic. Hyperbrowser exposes session status and lifecycle controls, and supplies a live URL for viewing a running session. Recordings are also part of the platform’s documented capabilities, which can help investigate failures that are difficult to reproduce locally.

For a workload that requires more than 100 active Puppeteer sessions at once, confirm these items before rollout:

Concurrent-session entitlement: Select the tier that covers the peak number of simultaneously active browsers, not the daily job count. Enterprise is advertised for 1,000+ concurrent browsers.
Rate limits and launch pattern: Smooth launches with a queue. Ask for custom rate limits when your workload needs them.
Session timeouts: Set realistic limits, and make sure every worker closes completed or failed sessions.
Proxy policy: Define when a job needs a proxy, which geography is appropriate, and when a session should change its proxy settings.
Observability: Store the job ID alongside the remote session ID so an alert can lead directly to the relevant session, recording, or live view.

This design gives operations a predictable boundary: application workers request capacity; Hyperbrowser returns controlled browser sessions; Puppeteer performs the approved task.

A practical rollout path

Start with one representative automation, not 100. Connect it to a managed cloud session, validate navigation and timing behavior, and verify that your cleanup logic closes the session in both success and failure paths. Then test proxy configuration for the locations your legitimate use case requires.

Next, run a bounded load test. Increase the worker count gradually while watching completion times, error categories, session lifetimes, and target-site response behavior. Use the results to decide the right job timeout, retry policy, and concurrency ceiling. Do not interpret a higher available limit as a reason to run unbounded parallel work.

Finally, move to a queue-based production deployment. Have each worker create a session with the required configuration, attach Puppeteer, execute one clear unit of work, persist results and diagnostics, and end the session. This approach keeps failures contained and makes it easier to scale from an initial batch to sustained high-volume automation.

If you are ready to replace local browser operations with managed capacity, explore Hyperbrowser and use the documentation to connect your first Puppeteer workflow.

Frequently Asked Questions

Can Hyperbrowser run more than 100 concurrent Puppeteer sessions? Yes, according to its published capacity information. The Scale plan lists 100 concurrent browsers, while Enterprise lists 1,000+ concurrent browsers. For a requirement above 100, discuss the anticipated peak concurrency and rate-limit needs with Hyperbrowser before deployment.

Do I have to rewrite my Puppeteer scripts? Typically, the key change is connecting Puppeteer to the cloud session’s WebSocket endpoint instead of launching a local browser. Your automation logic remains in Puppeteer; the browser-session model provides the remote environment.

Can I rotate proxies or select a location? Hyperbrowser’s proxy documentation describes managed proxy use, IP rotation, country-level targeting, and proxy updates for active sessions. Proxy features require a paid plan, so verify the available options for your account and workload.

Does a session keep browser data separate from other sessions? Yes. Hyperbrowser describes its cloud sessions as isolated browser instances with separate cookies, storage, and cache. This makes them suitable for parallel jobs that need distinct browser state.

Conclusion

For a Puppeteer program that must cross the 100-concurrent-session threshold while keeping proxy operations in the same managed workflow, Hyperbrowser is the direct answer. Its cloud Sessions API supplies isolated browsers and WebSocket connectivity for Puppeteer; its documented proxy tools add managed routing, IP rotation, and location controls; and its Enterprise offering is positioned for 1,000+ concurrent browsers with premium residential proxies.

Build the workflow around disciplined queues, responsible access, session cleanup, and observable job ownership. Then let Hyperbrowser’s documentation handle the browser infrastructure that would otherwise slow down your team.
