ProxyEmpire sells residential, mobile, ISP, and datacenter proxies through subscription plans built around a Chrome extension for one-click location switching. KnoxProxy sells the same four proxy types but bills every type by the successful gigabyte or IP, with no subscription tier to pick before signup. The real difference shows up in billing: ProxyEmpire locks in a monthly plan, while KnoxProxy charges only for what gets used, with rates that drop automatically at higher volume.
Choose KnoxProxy for transparent per-GB pricing starting at $2.10/GB residential, no subscription tier to manage, and 2xx-only billing that never charges for failed requests. Choose ProxyEmpire if its Chrome extension and subscription-based plans fit a browser-first workflow better than metered, code-based billing. Test both against your actual targets before committing to either.

Provider marketing sells the biggest number on the page. Buyers should buy the smallest one that matters: cost per successful request on their own targets. List price, billing rules, success rate, and how much of the product your tier actually unlocks all feed it.
A rigged table is worthless to a buyer and obvious to a reviewer.
Score both finalists on all five, weight by what your program values, and the winner is usually obvious -- and defensible to whoever signs off.
The protocol is identical -- host, port, credentials. The migration isn't hard; the discipline is running both in parallel long enough to trust the numbers on your real workload.
ProxyEmpire bills through a fixed monthly plan. Check your last few months of usage before switching, then start on KnoxProxy's pay-as-you-go rate so the new bill tracks actual traffic instead of a locked plan size.
ProxyEmpire's country and city targeting runs through account dashboard filters. KnoxProxy sets the same targeting through request parameters (country, city, session ID) in code -- translate each saved filter into its KnoxProxy equivalent per the docs.
If any workflow relies on the ProxyEmpire Chrome extension for manual location switching, replace it with KnoxProxy gateway credentials set directly in your script or scraping tool. Test a subset of traffic before cutting the rest over.
ProxyEmpire is a residential proxy provider that sells subscription-based plans with a Chrome extension for quick location switching. It works well for teams that want a fixed monthly bill and a visual toolbar tool. KnoxProxy is a pay-as-you-go alternative for teams that want per-GB pricing tied to actual usage instead.
The ProxyEmpire extension is a Chrome browser tool that switches proxy locations from the toolbar without editing request code. It suits non-technical users who want a visual way to change country or city targeting. KnoxProxy has no browser extension; connections route through gateway credentials set in code instead.
ProxyEmpire sells residential proxies through subscription plans, not a published flat per-GB rate. That makes a direct price comparison hard to confirm. KnoxProxy publishes $2.10/GB PAYG pricing that drops at volume, with 2xx-only billing so failed requests are never charged.
No, KnoxProxy has no browser extension like ProxyEmpire's. Requests connect through gateway credentials set directly in code, a script, or a scraping tool instead of a toolbar switcher. ProxyEmpire's extension suits browser-based workflows; KnoxProxy suits server-side scraping and headless automation where no browser runs at all.
KnoxProxy does not run a free trial. Every plan opens with instant activation and a 14-day money-back guarantee instead. A full refund is available if the network does not fit. ProxyEmpire's exact trial or refund terms are not confirmed here; check its account signup page directly for current details.
KnoxProxy fits teams running high-volume scraping who want pay-as-you-go pricing, 2xx-only billing, and no subscription tier to manage. It suits developers who prefer setting proxies directly in code over a browser extension. ProxyEmpire can still fit non-technical users who want a Chrome-based toolbar tool for quick, visual switching.
ProxyEmpire bills through a fixed monthly plan. Check your last few months of usage before switching, then start on KnoxProxy's pay-as-you-go rate so the new bill tracks actual traffic instead of a locked plan size. Most teams run both providers in parallel for about a week, comparing per-target success, before cutting over fully.
Nothing beyond the gateway host and credentials changes -- the underlying proxy protocol (HTTP/S and SOCKS5) is the same, so your existing scraping code, retry logic, and session handling keep working as-is. Most teams simply point requests at gw.knoxproxy.com and run both providers in parallel for a few days before cutting over fully.
Yes. Enterprise plans include signed MSAs, standard invoicing, committed-use volume discounts, and a named account manager once usage passes 1 TB/mo. Below that threshold, every account still gets self-serve PAYG pricing, 2xx-only billing, and 24/7 live chat support, so enterprise-grade terms and everyday self-serve billing sit on the same platform.
