## Our products

### [<mark style="color:green;">Residential proxies</mark>](/eng/our-products/residential-proxies.md)

Real IP addresses from residential and mobile providers in **250+ locations**. The total pool contains more than **3,000,000 addresses**. They provide a high level of anonymity, making them an excellent choice for crypto services, SEO, multi-accounting, and other tasks where IP cleanliness matters.

### [<mark style="color:orange;">Datacenter proxies</mark>](/eng/our-products/datacenter-proxies.md)

Some of the most stable and fastest proxies with a **static IP**. Each address is assigned to only one user. They support UDP and p0f switching. Suitable for tasks that require speed and a fixed IP without rotation. All servers in each location include a guaranteed 10 Gbps channel, high uptime, and low ping thanks to excellent peering from our datacenter providers.

### [<mark style="color:blue;">ISP proxies</mark>](/eng/our-products/isp-proxies.md)

Proxies from residential internet providers in different countries. They combine the advantages of Datacenter and Residential proxies: the uptime and speed of a static DC IP with the trust profile of a residential provider. As with Datacenter proxies, addresses are issued strictly to one user and also support UDP and p0f switching.

### [<mark style="color:red;">Mobile proxies</mark>](/eng/our-products/mobile-proxies.md)

Proxies with flexible country and carrier selection. They have a single connection address, allow IP changes via a link, and support p0f fingerprint spoofing (device signature).

### [<mark style="color:purple;">IP Checker</mark>](/eng/our-products/ip-checker.md)

The first free tool on the market for assessing not only IP quality but also the quality of your browser profile.

They support proxy assessment by IP origin type, UDP availability, and FakeISP detection based on many signatures.

They also check profile quality and cleanliness based on browser fingerprints and other parameters collected by advanced antifraud systems.

### [<mark style="color:purple;">Proxy Tester</mark>](/eng/our-products/proxy-tester.md)

One of the most accurate testers on the market, because it includes not only a basic status-response check but also checks whether a proxy supports UDP, since not all services sell proxies with UDP support.
