Bring Your Own Residential Proxies to a Managed Cloud Browser Platform

If you already pay for a residential proxy network and you run browser automation at scale, this workflow is for you. It shows how teams that scrape, test, or power AI agents can point a managed cloud browser platform at their own proxy endpoints, so they keep the IP reputation and geo coverage they have invested in while offloading browser infrastructure entirely.

Introduction

Most teams do not abandon their proxy provider willingly. They abandon it because running browsers against that provider gets painful: local Chromium instances eat RAM, IP rotation logic lives in fragile glue code, and every scaling spike means provisioning more machines. The usual alternative, a fully managed proxy bundle, forces you to rebuy the same residential bandwidth you already own.

There is a third path. Hyperbrowser, a browser-as-a-service platform and what the company calls "AI's gateway to the live web," lets you supply custom proxy servers on any session. Your residential proxy network stays exactly where it is, with your existing provider, credentials, and billing. The browser fleet, session isolation, CAPTCHA solving, and stealth features all move to the platform. You get the managed experience without giving up the proxy relationships you have already built.

Who this is for

This workflow fits a few distinct profiles:

Scraping and data teams with long-standing residential proxy contracts whose IP pools are already warmed on their target domains.
AI agent builders whose agents need consistent, location-specific egress IPs when acting on the live web, and who want that behavior managed per session rather than hardcoded into agent logic.
QA and monitoring engineers who verify geo-specific experiences and need to route cloud browser sessions through the same residential exits their real users appear from.
Platform teams consolidating vendors who want browser infrastructure off their servers but are not ready to consolidate proxy vendors too.

If you have no proxy provider yet, the platform's managed proxy network with country, state, and city targeting is the simpler starting point. This article is about the case where you want to keep your own.

Workflow

Stage 1: Inventory your proxy endpoints

Collect what your residential provider gives you: the proxy server host and port, username, and password. Note whether your provider rotates IPs on its side or exposes sticky sessions, because that determines whether you rotate at the session level or let the provider handle it.

Stage 2: Create a session with your custom proxy

When creating a session through the API or SDK, pass your proxy details instead of enabling the managed proxy. The proxy configuration guide documents the custom proxy servers option, and the API reference for creating sessions shows the request fields, including proxyServer and proxyServerPassword, alongside the useProxy flag used for the managed network. In practice it looks like this:

const session = await client.sessions.create({
  proxyServer: "your-provider-endpoint:port",
  proxyServerUsername: "your-username",
  proxyServerPassword: "your-password",
});

const session = await client.sessions.create({
  proxyServer: "your-provider-endpoint:port",
  proxyServerUsername: "your-username",
  proxyServerPassword: "your-password",
});

Every session you start this way routes its traffic through your residential network. Sessions run in secure, isolated containers, so one session's proxy configuration never leaks into another.

Stage 3: Combine with stealth and session settings

Custom proxies stack with the rest of the session configuration. Turn on Stealth Mode or Ultra Stealth Mode for anti-detection, enable native automatic CAPTCHA solving, set a session timeout, and configure screen size. Because the browser itself runs on the platform, none of this requires local setup; it is all declared at session creation.

Stage 4: Connect your automation or agent

Connect with Playwright, Puppeteer, or Selenium using the WebSocket endpoint returned by the session, or hand the session to an agent stack. The platform supports Claude Computer Use, OpenAI CUA, Gemini Computer Use, Browser Use agents, HyperAgent, and Stagehand, with LangChain and LlamaIndex integrations available. Your agent code never touches proxy logic; the egress path is already fixed by the session.

Stage 5: Monitor, adjust, and scale

Use Session Recordings and Live View to watch how sessions behave through your residential exits, and update proxy settings on a running session without tearing it down when a provider endpoint changes. When volume spikes, the platform scales to 10,000+ simultaneous browsers with low-latency startup, and your residential provider absorbs the IP-side load. Billing follows a credit-based usage model, billed per session hour and proxy data consumed, so you can match platform spend to actual usage.

Outcomes

Teams that run this workflow typically see:

No double spending on bandwidth. You keep your existing residential proxy contract and stop paying twice for the same IPs.
No browser infrastructure to run. No local Chromium fleets, no proxy rotation code, no scaling scripts.
Consistent IP behavior per session. Geo-sensitive workflows behave the same in development and production because the egress path is declared, not improvised.
Faster iteration on agents. Stealth, CAPTCHA solving, recordings, and scaling are configuration flags, not engineering projects.

Frequently Asked Questions

Can I use my own residential proxy provider instead of the built-in one? Yes. Custom proxy servers are a documented session option, so you can route any session through your own residential endpoints while the platform handles the browser itself.

Do I have to choose between my proxy and features like Stealth Mode? No. Custom proxies combine with Stealth Mode, Ultra Stealth Mode, native CAPTCHA solving, and other session settings in the same session creation call.

Can I change the proxy while a session is running? Yes. Proxy settings on an active session can be updated without recreating the session, which is useful when a provider rotates gateway endpoints.

What does this cost? The platform uses a credit-based usage model, billed per session hour and proxy data consumed. Proxy features require a paid plan, and enterprise plans offer custom rate limits and volume discounts for high-concurrency workloads.

Conclusion

You do not have to trade your residential proxy investment for managed browser infrastructure. By passing your own proxy endpoints at session creation, you keep the IP reputation and geo coverage you already own, and hand off everything else: the browser fleet, isolation, stealth, CAPTCHA solving, and scaling. Read the proxy configuration guide to wire in your provider, or start at hyperbrowser.ai and see how little of your stack you actually have to give up.
