A proxy provider comparison is only as good as its dates. Prices, pools and policies all move, so every number below carries the day it was read, and anything we could not read is marked as unverified rather than filled in.
What we know about SigmaProxies, and what we do not
Their site is sigmaproxies.com.
We price the providers we can source and date, and SigmaProxies is not currently one of them. The rest of this page is about what to check when you read their pricing yourself.
The four figures worth copying down are the rate without a commitment, the smallest purchase allowed, what happens to unspent balance, and whether a failed request still costs money.
The site, as it reads today
On 9 September 2026 the site introduced itself as "SigmaProxies.com, The Ultra High Quality Proxies Provider You Need". In the description they hand to search engines: "SigmaProxies.com The Ultra High Quality Proxy Provider, get your residential,datacenter and mobile proxies all in one place at a fairly low price."
The rest of what the page puts in writing:
The product lines named on that page are residential, datacenter, mobile and SOCKS5. Support is advertised as around the clock. We found no separate pricing page linked from the homepage, which usually means the price arrives by quotation.
Every line above is a quotation from their marketing rather than a measurement by us. It is included because it is checkable, not because it is evidence of performance.
How long SigmaProxies has been trading
The domain was registered on 25 March 2023, through NameCheap, Inc, which makes it about 3 years old. The lookup behind those dates ran on 9 September 2026. As things stand the domain is held to 25 March 2027.
This proves nothing about the product. It is a cheap check against the one failure mode that costs buyers real money in this market, which is paying a provider that will not exist in six months.
What you still do not know after reading their site
Why the pool number is the least useful figure
Nobody audits pool totals in this market, and the counting rules differ between vendors. Even an accurate figure describes addresses that exist, not addresses you will be routed through. Treat it as a marketing unit rather than a capability.
What the starting rate leaves out
Rates in this market are quoted from the bottom of the table. The relevant question is which row you land on at your volume, and whether reaching a cheaper row costs more in commitment than it saves per unit.
Concurrency limits decide throughput
Rate limits are often enforced per account rather than per plan, which means buying more traffic does not raise them. Confirm how yours scales before you assume a bigger plan runs faster.
The two of us, on the questions that matter
Six questions, both answers, and an honest blank where we do not hold a current figure:
| Question to ask | SigmaProxies | HProxy |
|---|---|---|
| Entry price | Not verified by us, read their page | From $0.44/GB, pay as you go |
| Does unused balance expire? | Read their current terms | Never |
| Minimum commitment | Check the current terms, this one moves | None |
| Identity checks | Their terms page answers this | Card orders are screened, and verification is sometimes requested |
| Targeting | On their own terms page | Country, city and ISP |
| Free way to evaluate | Not published clearly, ask before paying | Free proxy list and proxy checker |
Read the table as a list of questions rather than a scoreboard. The answers on their side move, and the row that decides the outcome, success rate on your target, is not printable by anyone.
What to do instead of reading more comparisons
The steps below take about ten minutes and settle the question properly.
- Fund both accounts with the least money each will accept, and note what that minimum was, because it is part of the comparison.
- Aim both at the page that matters to you rather than a test endpoint, and keep every other variable fixed.
- Write down two numbers per provider: the share of requests that succeeded, and the traffic it cost.
- Take a handful of the addresses you were given and verify their country and type against a checker you do not control.
- Go with whichever performed, then measure again next quarter. Networks change underneath you.

Our own position
Residential starts at $0.44 per GB, the balance never expires, there is no minimum commitment and no sales call, and city and ISP targeting are included. We publish our free side openly, 129,131,311 verification checks and counting, because a network that is confident has no reason to fear measurement.
