Proxy-Seller sells individual dedicated IP addresses priced per unit, while KnoxProxy sells shared-pool access priced per successful gigabyte. Proxy-Seller runs five separate proxy classes -- datacenter IPv4, datacenter IPv6, ISP static residential, rotating residential, and mobile 4G/5G -- each billed on its own per-IP or per-GB schedule. KnoxProxy keeps one model across residential, datacenter, ISP, and mobile: pay for the data that actually reaches its destination, nothing more.
Choose KnoxProxy if you want one predictable per-GB rate across every proxy type, plus 2xx-only billing so blocked or failed requests are never charged. Choose Proxy-Seller if a task specifically needs an individually owned static IP that nobody else ever touches, such as long-term social account management on one fixed ISP or datacenter address.
| KnoxProxy | Proxy-Seller | |
|---|---|---|
| Residential price /GB | $2.10 PAYG (to $1.10) | $3.50/GB entry tier (to ~$2.20 at 100 GB) |
| IP ownership model | Shared rotating pool | Individually owned dedicated IPs |
| Datacenter pricing model | $0.60/GB usage-based | From $0.70/IP flat monthly rental |
| ISP (static) pricing model | $2.90/IP, unlimited bandwidth | From $1.50/IP flat monthly rental |
| Mobile pricing model | $4.50/GB usage-based | Reportedly $25-$80/IP monthly |
| Failed-request billing | Never billed (2xx-only) | Flat per-IP rental or standard metered GB |
| Countries | 195 | 220+ (self-reported) |
| City / ASN targeting | All plans, self-serve | Residential only; datacenter/ISP targeting is country-level |
| Getting started | Instant, 14-day money-back | Instant, 24-hour replacement/refund on new IPs |
| Task | Pick | Why |
|---|---|---|
| Long-term account management needing one fixed, owned IP | Proxy-Seller | A dedicated ISP or datacenter IP stays assigned to one buyer for the length of the rental, unlike a shared rotating pool. |
| High-volume rotating scraping across many targets | KnoxProxy | One per-GB rate and 2xx-only billing beat tracking and renewing dozens of individually priced IPs. |
| Budget IPv6-only workloads on IPv6-friendly targets | Proxy-Seller | Its roughly $0.08/IP IPv6 datacenter tier undercuts any per-GB residential or datacenter rate on the market. |
| Teams that want one billing model across every proxy type | KnoxProxy | Residential, datacenter, ISP, and mobile all bill the same way: per successful gigabyte, with no per-IP math. |
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.
Pool size and pool quality are different axes. A large pool of recycled, previously flagged addresses can lose to a smaller, well-maintained one on your actual targets. Compare the numbers below, then verify with your own benchmark -- ask about IP hygiene, not headcount.
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.
Audit any Proxy-Seller datacenter, ISP, or mobile IPs tied to long-running sessions or account logins. Those depend on one fixed address and are not a direct swap to a shared rotating pool -- plan them separately from bulk scraping traffic.
For rotating residential and general scraping traffic, replace Proxy-Seller's host and credentials with gw.knoxproxy.com and your KnoxProxy login. This covers most volume-driven, per-GB workloads in one config change.
Proxy-Seller handles city-level residential targeting through a support request after purchase. KnoxProxy exposes city and ASN targeting directly as request parameters on every plan -- set these natively instead of filing a support ticket.
Yes, for teams that want one per-GB rate instead of separate per-IP rentals across proxy types. KnoxProxy's 2xx-only billing and flat pricing across residential, datacenter, ISP, and mobile simplify budgeting. Proxy-Seller still fits better when a job needs one specific IP owned outright.
Proxy-Seller rents datacenter, ISP, and mobile IPs individually, each priced per IP per month, separate from its per-GB residential plans. You pay for the IP itself regardless of how much data crosses it. KnoxProxy instead bills every proxy type per successful gigabyte used.
Proxy-Seller states that every purchased IP is exclusively assigned to that buyer for the rental period, unlike a shared rotating pool. This suits long-session account work. KnoxProxy's residential and mobile IPs rotate through a shared pool instead of one dedicated address.
Third-party proxy service reviews generally rate Proxy-Seller well on pricing flexibility and dedicated IP ownership, with mixed notes on support response time. As with any proxy service review, test the actual product against your own targets rather than relying on review scores alone.
Proxy-Seller publishes stacking discounts: a volume discount for buying 10 or more IPs, a multi-month rental discount, and an auto-renewal discount, plus periodic promo codes on top. Codes and percentages change over time, so check their current pricing page before assuming a specific rate.
Proxy-Seller reports 220+ countries with dedicated pages for 40+ individual markets; KnoxProxy covers 195 countries with city and ASN targeting on every plan. Raw country count matters less than whether your specific target markets have deep, reliable IP density on either network.
Audit any Proxy-Seller datacenter, ISP, or mobile IPs tied to long-running sessions or account logins. Those depend on one fixed address and are not a direct swap to a shared rotating pool -- plan them separately from bulk scraping traffic. 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.
