5StarsProxy is a proxy service provider offering IPv4 options for customers in Vietnam and the United States. Its catalog includes static residential proxies, private residential proxies, Vietnamese datacenter proxies, US datacenter proxies, and rotating proxy products. Vietnamese residential IPs are available through Viettel, VNPT, and FPT, while the site describes its datacenter servers as located at CMC in Hanoi and in San Jose, California.

Customers can choose between HTTP and SOCKS5 connections, select available proxy types or locations, and purchase for a chosen number of days. The service advertises unlimited data usage on several listed plans, dedicated-use options, and lower prices for longer subscription periods. Vietnamese datacenter packages offer shared or private configurations, and private residential proxies are presented as exclusively assigned.

The website also provides account registration and login, payment top-ups, order and usage histories, proxy-checking tools, an application download, and API access for static IPv4 and rotating residential proxies. Support is offered through Zalo and Telegram
