TL;DR

Price monitoring means checking the same product pages hundreds or thousands of times a day. The proxy that wins is the one that fails least, answers fastest, and stays affordable at volume. Based on 90-day independent benchmarks:

• Best overall: Squid Proxies. It is #1 on the residential Index (97.5/100), with the fastest datacenter speeds tracked.
• Best pay-as-you-go: DataImpulse. Residential at $1.00/GB with no monthly commitment.
• Most stable datacenter: ProxyScrape. Its datacenter proxies show 100.0% reliability over 90 days.
• Cheapest datacenter entry: Webshare. 100 datacenter IPs for $2.99/month.
• Cheapest residential per GB: Evomi. $0.49/GB, though its reliability swings more than most.

Comparison table

Index = the benchmark's 0–100 score that weights reliability 50%, speed 25% and latency 25%. Prices are for roughly 100 GB or 100 IPs per month.

How we evaluated

The ranking follows independent benchmark data from ProxyPerf. It buys commercial access to each provider and sends requests on a repeating schedule. It records three things for every request:

• Reliability: the share of requests that complete. This matters most for price monitoring, because a failed check is a missed price change.
• Speed: average download rate in Mb/s, not peak speed.
• Latency: average round-trip time in milliseconds.

The Index combines these at 50% reliability, 25% speed and 25% latency. It is scored against fixed thresholds and averaged over a rolling 90 days. Price is kept out of the Index, so we list it separately using its pricing comparison and each provider's own plans page.

We ordered the list by the residential Index, for one reason: large retailers often run bot protection, and residential IPs get through it more often. We show the datacenter Index next to it because datacenter proxies are cheaper and faster for sites that don't block them.

Proof: price monitoring runs nonstop, so bandwidth caps matter. On ProxyPerf's pricing comparison, Squid Proxies costs $100/month for 100 dedicated datacenter IPs with unlimited data, or $1.00 per IP. Other dedicated datacenter IPs start higher on the providers' own pricing pages: Oxylabs from $1.20, IPRoyal from $1.39 (90-day plan) and Proxy-Cheap at $1.42 per IP per month. Proxy-Cheap's $1.13 is a 7-day trial price. Cheaper options are shared IPs, such as Oxylabs' shared plan from $0.70/IP, or are sold only in 1,000-IP bundles (PlainProxies €50, ProxyScrape $75).

The 8 best proxies for price monitoring

All figures are 90-day averages to November 2026 unless noted.

1. Squid Proxies

Best for: high-frequency price checks on protected retail sites.

Residential: 99.7% reliability, 564 ms latency, 34.9 Mb/s. Datacenter: 98.6% reliability, 332 ms, 175.7 Mb/s.

• Pro: the fastest datacenter speed and lowest datacenter latency tracked. Dedicated datacenter IPs include unlimited bandwidth.
• Con: its datacenter service ranks #4. Its 12-month datacenter reliability is the lowest tracked (81.0% in a typical month), though it has recovered to 99.9% in November.
• Con: a smaller residential pool in the benchmark sample: 43.9K unique IPs, against 100K+ for most rivals. Large multi-country catalogs may hit geo gaps.

Pricing: residential from $15/month (10 GB) down to $0.75/GB on 400 GB. Dedicated datacenter from $1.50/IP (10 IPs) down to $0.80/IP (500 IPs). Residential IPs rotate every 5 minutes.

2. DataImpulse

• Pro: #2 residential Index (87.4), with pay-as-you-go billing and no monthly minimum.
• Con: more than double SquidProxies' latency, which slows large crawls. Its datacenter service ranks #10 (73.5).

Pricing: residential $1.00/GB pay as you go, from $5 for 5 GB down to $0.80/GB at 1 TB, and traffic never expires. Datacenter $0.50/GB pay as you go ($50 for 100 GB), down to $0.45/GB at 1 TB.

3. ProxyScrape

Best for: datacenter monitoring that must not miss a check.

Datacenter: 100.0% reliability, 447 ms, 56.2 Mb/s. Residential: 98.1%, 1,577 ms, 17.1 Mb/s.

How to choose a proxy for price monitoring

1. Start with reliability. Every failed request is a price you didn't see. Below 95%, about 1 check in 20 fails.
2. Match the proxy type to the site. Use residential proxies for retailers with bot protection, and datacenter proxies for sites that allow them. Datacenter costs less and runs much faster.
3. Do the math at your real volume. Multiply products by checks per day by page size. Unlimited-bandwidth datacenter plans usually win for heavy, frequent crawls. Per-GB residential plans suit smaller, protected targets.
4. Check geo coverage. Regional pricing needs IPs in each country you track, so check the provider's geo-targeting options.
5. Look at the trend, not one month. Use 90-day or 12-month data. Single months swing a lot. Evomi went from 39% to 100% within a year.

FAQ

What is the best proxy type for price monitoring? Residential proxies work best on retailers with bot protection. Datacenter proxies are cheaper and faster for sites that don't block them. Many teams use both.

Which proxy provider is fastest for price monitoring? In the independent speed benchmark, Squid Proxies averaged 33.0 Mb/s on residential and 134.8 Mb/s on datacenter over the last 12 months. That is the fastest of every provider tracked.

How reliable should a price monitoring proxy be? Aim for 98% or higher. Below 95%, roughly one request in twenty fails.

Are datacenter proxies good enough for price monitoring? Yes, for sites that don't filter datacenter IPs. ProxyScrape and PlainProxies both scored 99.9% or higher on datacenter reliability over 90 days.
