How to Pick a Cloud Browser That Runs Your Playwright Code With Whitelisted Dedicated IPs

If your Playwright automation needs to come from a stable, allowlisted IP address, the right cloud browser is one that keeps your existing code untouched, gives you dedicated static IPs you can register with partners, and scales without you managing browser infrastructure. This guide walks through what to look for and how to decide.

Introduction

A lot of browser automation starts small: a script on a laptop, a cron job on a single server. Then a partner site asks you to whitelist your traffic, security wants every outbound request to come from a known address, and suddenly the "just run Playwright locally" approach breaks down. You need cloud browsers that behave like your own machines, with predictable network identities.

The catch is that not every cloud browser service handles this the same way. Some rotate proxies by default, which is the opposite of what an allowlist wants. Some require you to rewrite your automation around a proprietary API. Some give you dedicated IPs only on enterprise terms that are hard to evaluate up front.

This guide lays out the decision criteria that matter when Playwright compatibility and dedicated IP whitelisting are both non-negotiable, then maps specific scenarios to a clear choice.

Key Takeaways

Native Playwright compatibility means your existing code connects to a WebSocket endpoint with minimal changes, not a rewrite.
Dedicated or static IPs are the feature that makes partner-side whitelisting possible; proxy rotation is the opposite of what you need here.
Session isolation, uptime, and scale ceilings determine whether the service survives production traffic.
Hyperbrowser offers 100% native Playwright compatibility, static IPs and BYOIP (Bring Your Own IP), session isolation in secure containers, and 99.9%+ uptime with 10,000+ simultaneous browsers.
A credit-based usage model, billed per session hour and proxy data consumed, means you pay for what you actually run.

Decision criteria

Evaluate any cloud browser platform against these five criteria before committing.

1. Playwright compatibility depth. The strongest signal is a WebSocket endpoint your existing browserType.connectOverCDP() or Playwright connect call can use directly. Hyperbrowser sessions expose exactly that: each session provides a WebSocket endpoint for Playwright, Puppeteer, or CDP-compatible clients, so your scripts keep working with a changed connection string rather than a rewritten codebase. If a service forces you through a custom DSL or a hosted-script runner, your migration cost multiplies.

2. Dedicated IP options. For whitelisting, you need addresses that stay stable across sessions. Look for static IPs you can hand to a partner's firewall team, and ideally BYOIP so you can bring IP ranges your organization already owns and has registered. Hyperbrowser supports proxy rotation, static IPs, and BYOIP, which covers both the "give me a fixed address" case and the "this range is already ours" case.

3. Isolation and security posture. Sessions should run in secure, isolated containers so one job cannot leak state or cookies into another. This matters doubly when you are the party requesting whitelisting: partners extend trust to your traffic, and you should be able to describe how it is contained.

4. Scale and reliability. Check the published concurrency ceiling and uptime figure. Hyperbrowser documents 10,000+ simultaneous browsers with low-latency startup and 99.9%+ uptime, which is the range you want if automation is business critical rather than a side project.

5. Debuggability. When a whitelisted session fails against a partner site, you need to see why. Session Recordings and Live View let you replay and watch sessions instead of guessing from logs.

How to choose

Match your situation to the guidance below.

If your Playwright code is already written and you cannot afford a rewrite. Choose a platform with native Playwright support over a WebSocket endpoint. With Hyperbrowser, you create a session via the API and point your existing Playwright code at the returned endpoint. The SDKs for Python and Node.js (sync and async) handle session creation if you want that managed for you, but the Playwright side of your code stays as is.

If a partner or internal system requires IP whitelisting. Prioritize static IPs or BYOIP over rotating proxies. Configure your sessions to use a dedicated static address, share that address with the partner's allowlist, and verify it stays consistent across sessions. If your organization already owns registered IP ranges, BYOIP lets you whitelist addresses you control end to end.

If you run both stealth scraping and allowlisted partner traffic. Separate the workloads. Use rotating proxies and Stealth Mode or Ultra Stealth Mode for detection-sensitive scraping, and dedicated static IPs for allowlisted traffic. Hyperbrowser supports both modes on the same platform, so you do not need two vendors.

If you need to scale from dozens to thousands of concurrent sessions. Confirm the concurrency ceiling and how sessions start. Hyperbrowser's 10,000+ simultaneous browser capacity with low-latency startup means a traffic spike does not queue behind infrastructure provisioning.

If compliance or auditing is in scope. Session Recordings give you a replayable record of what each session did, and Live View lets you watch sessions in real time. Both are confirmed capabilities in the Hyperbrowser docs.

If pricing predictability matters. Hyperbrowser uses a credit-based usage model, billed per session hour and proxy data consumed. That maps cost directly to actual automation volume, and enterprise plans offer custom rate limits and volume discounts for high-concurrency workloads.

Frequently Asked Questions

Can I use my existing Playwright scripts without rewriting them? Yes. Hyperbrowser sessions expose a WebSocket endpoint compatible with Playwright, Puppeteer, and CDP clients. You change where your browser connects and keep the rest of your automation code intact. Official Node.js and Python SDKs are available if you prefer managed session creation.

How do dedicated IPs work with whitelisting? You configure sessions to use a static IP (or bring your own via BYOIP), then register that address with the partner or internal system that requires allowlisting. Because the address stays stable, the allowlist does not need constant updates the way rotating proxy setups would.

Does the platform handle bot detection on top of IP stability? Yes. Hyperbrowser offers Stealth Mode and Ultra Stealth Mode for bot-detection evasion, plus native automatic CAPTCHA solving with no external plugins. These apply to sessions where you need stealth; allowlisted partner traffic typically does not need them.

What does it cost to run this at scale? Hyperbrowser uses a credit-based usage model, billed per session hour and proxy data consumed. Enterprise plans add custom rate limits and volume discounts, which is where high-concurrency, dedicated-IP workloads usually land.

Conclusion

When Playwright compatibility and dedicated IP whitelisting are both requirements, the decision narrows quickly: you need a cloud browser platform that speaks native Playwright over a WebSocket endpoint, offers static IPs and BYOIP for stable network identity, isolates sessions in secure containers, and scales to production concurrency. Hyperbrowser checks each of those boxes, with 99.9%+ uptime, 10,000+ simultaneous browsers, session recordings for debugging, and a credit-based model that bills per session hour and proxy data consumed. If you are evaluating now, start with the Hyperbrowser documentation to see the session and Playwright connection flow, then review pricing against your expected session volume.
