## Our products

### [<mark style="color:green;">Residential proxies</mark>](#rezidentskie-proksi)

Real IP addresses from home and mobile providers in **250+ locations**. Total pool — more than **3,000,000 addresses**. They have a high degree of anonymity, which makes them an excellent choice for working with crypto services, SEO, multi-accounting, and other tasks where IP cleanliness matters.

### [<mark style="color:orange;">Datacenter proxies</mark>](#nashi-produkty)

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 swapping. Suitable for tasks that require speed and a constant IP without rotation. All servers in each location include a guaranteed 10-gigabit channel, high uptime, and low ping thanks to the excellent peering of our datacenter providers.

### [<mark style="color:blue;">ISP proxies</mark>](#isp-proksi)

Proxies from home internet providers in different countries. They combine the advantages of datacenter and residential proxies: the uptime and speed of a static DC IP and the trust of a home provider. Addresses, like datacenter proxies, are issued strictly to one user, and also support UDP and p0f swapping

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

Proxies with flexible country and specific carrier selection. They have a single connection address, allow you to change the IP via a link, and also spoof the p0f fingerprint (device signature).

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

Includes a check of the profile’s quality and cleanliness based on browser fingerprints and other parameters collected by all advanced anti-fraud systems

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

One of the most accurate testers on the market, since it includes not just a standard status-response check, but also checks proxies for UDP support, since far from all services sell proxies with this support
