What is ShardX

ShardX (formerly ProxyShard) brings together Residential, Datacenter, ISP, and Mobile proxies with tools for browser workflows, testing, and automation. Datacenter and ISP addresses are assigned to one customer and are not shared. Availability of UDP, p0f switching, and other features depends on the product and location.

Our products

Residential proxies

IP addresses from residential and mobile providers with configurable location, session type, and connection parameters. They suit tasks that require a varied address pool and a regular consumer network profile.

Datacenter proxies

Fast static proxies with dedicated IP addresses. They suit long-running sessions and tasks that require a stable connection, high speed, and a consistent address.

ISP proxies

Static addresses hosted on internet service provider networks. They combine the stability of Datacenter proxies with an ISP network profile and are assigned to one customer.

Mobile proxies

Mobile carrier proxies with country and carrier selection. You can rotate the IP through a link, while available settings depend on the selected plan and location.
