Redundant infrastructure keeps long-running sessions alive
Automation engineers, QA testing teams, headless browser operators, and web scraping developers depend on browser proxies. Roundproxies delivers infrastructure optimized for Puppeteer, Playwright, Selenium, and other browser automation frameworks—essential for running distributed testing suites, automated data extraction pipelines, and parallel browser instances without detection.
Browser automation scripts fail catastrophically with free proxies due to inconsistent connections that break session state, SSL errors that halt headless operations, and IP bans that invalidate hours of scripted workflows. Roundproxies provides stable, automation-friendly proxies with proper WebSocket support and persistent sessions critical for multi-step browser scripts and long-running automation tasks.
Optimized specifically for browser automation frameworks, our proxy network delivers low-latency connections that minimize page load times and script execution delays. Support for concurrent browser instances enables parallel testing and scraping operations at scale. WebSocket compatibility ensures modern web applications function correctly, while connection pooling reduces overhead in rapid page navigation scenarios.
Residential proxies prove essential when browser scripts must appear as genuine human users to bypass sophisticated bot detection systems. Datacenter proxies excel for internal testing, development environments, and scenarios where speed outweighs stealth requirements. Our infrastructure supports sticky sessions critical for multi-page automation workflows while offering rotation for distributed scraping operations across thousands of browser instances.
Headless browsers get blocked for two separate reasons, and a proxy fixes only one of them. The address is scored by every target; the browser fingerprint is scored by the harder ones. Puppeteer, Playwright and Selenium users who buy residential addresses and keep a default headless fingerprint get blocked and blame the proxy. This page is about which address type each class of target needs, and how to assign it per browser context without leaking.
| Proxy type | Verdict | Why |
|---|---|---|
| Datacenter | Unprotected targets | Fast and cheap for sites with no bot management — internal tools, most small sites, many APIs. Blocked at the edge by anything running an enterprise bot manager, whatever the fingerprint. |
| Rotating residential | Protected targets, per context | A fresh household address per browser context for scraping sites that score the address. Pair it with a realistic fingerprint or the address is wasted. |
| ISP (static residential) | Persistent profiles | A fixed consumer address for a browser profile that logs in and stays logged in — account testing, monitoring behind auth, anything with a session that must survive. |
| Sticky residential | Multi-page flows | One address held across a checkout, a form, or a paginated crawl where a change of address mid-flow breaks the session. |
| 4G / 5G mobile | Mobile-app emulation | For automation that emulates a mobile app or tests mobile-specific behaviour. Expensive for general crawling. |

Match the address type to the target's defence, then match the fingerprint to the address. One without the other fails.
Address scoring, fingerprint scoring, and leaks between the two.
Targets with bot management score the address's ASN, history and rate before rendering anything. This is the part a proxy fixes: the right type for the target, rotated or held according to the flow.
Proxy setup: Datacenter for unprotected targets, rotating residential for protected ones, ISP or sticky for flows that need one address.
The harder targets score the browser itself: headless markers, missing plugins, canvas and WebGL consistency, timezone versus address. A residential address with a headless fingerprint is caught as surely as a datacenter one.
Proxy setup: A fingerprint consistent with the address — timezone, locale and language matching the address's country — from a stealth configuration or a real browser profile.
WebRTC, DNS resolution outside the proxy, and requests from workers or extensions that bypass the context's proxy all expose the real address.
Proxy setup: Disable WebRTC or force it through the proxy, resolve DNS through the proxy, and verify from a leak-test page before every run.
Playwright and Puppeteer support a proxy per context. One context per address keeps sessions and cookies isolated with their address.
Chromium does not support SOCKS5 with a username and password. Use our HTTP endpoints with credentials, or whitelist your machine's address and use SOCKS5 unauthenticated.
Set the context's timezone, locale and Accept-Language to the address's country. A German address with a Pacific timezone is a fingerprint mismatch.
Residential traffic is billed by volume. Block images, fonts and media in contexts that only need the DOM, and residential costs drop by most of the page weight.
Load a leak-test page in a proxied context and confirm the visible address, the WebRTC address and the DNS resolver are all the proxy's.
A paginated crawl or a checkout holds one address; independent page fetches rotate. Decide per job.
Sized on concurrent contexts for static addresses, on page weight times pages for residential traffic.
| What you are running | Proxies you need | Notes |
|---|---|---|
| A handful of logged-in monitors | 1 ISP per profile | One fixed address per persistent profile. The trial covers a few. |
| Crawling unprotected sites, 20 contexts | 20 datacenter IPs | One per concurrent context; cheap and fast. |
| Scraping protected sites | Rotating pool by GB | Size on pages times average page weight after blocking assets. |
| Checkout or form flows | Sticky residential per flow | One held session per concurrent flow. |

tbh, I had a very good run with roundproxies. the support is top tier and the quality of the proxies ahve been premium since day one. Have used their ISP and Residential proxies and love the granuliar targeting I can do. I would recommend roundproxies.
The proxy quality and success rate is what stands out most. The IPs are clean, connections are fast, and I rarely hit blocks even on tougher targets. The dashboard is dead simple, I was up and running in minutes, and whenever I had a setup question, support answered within minutes and actually knew what they were talking about. For the price, especially the datacenter proxies with unlimited bandwidth, the value is hard to beat.
I purchased proxies today the first time in my life, not knew where to start. Marius responded within minutes and helped me understand everything right away. Very fast and helpful support.
The Datacenter Proxies arrived and missing an item. I immediately contacted customer service who sent me another Datacenters for and added one week for free on top.

Because the address is only half of what protected targets score. The browser's fingerprint — headless markers, missing plugins, canvas and WebGL consistency, a timezone that contradicts the address — is the other half. A residential address under a default headless fingerprint is caught as surely as a datacenter one.
No. Chromium does not support SOCKS5 with a username and password, and it fails silently. Use our HTTP endpoints with credentials, which Chromium handles through the proxy authentication callback, or whitelist your machine's address with us and use SOCKS5 without credentials. Either way, confirm with a leak test that the context is actually routing through the proxy.
Per browser context, not per process. Playwright and Puppeteer support a proxy per context, so one context per address keeps sessions and cookies isolated with their address. Set the context's timezone, locale and Accept-Language to the address's country at the same time.
Block what the job does not need. Residential traffic is billed by volume, and a page's images, fonts and media are most of its weight and none of its value for DOM extraction. Block those resource types in contexts that only need the document, and costs drop by most of the page weight.
Load a leak-test page in a proxied context before every run and confirm the visible address, the WebRTC address and the DNS resolver are all the proxy's. WebRTC, local DNS resolution and requests from workers or extensions that bypass the context's proxy are the usual leaks.
