Why free tools?
ProxyNest started as a proxy list, but the same people who need proxies also need quick answers: what is my IP right now, is this proxy actually working, which country am I appearing from. Instead of sending you to ad-covered tool sites, we build the essentials here, kept fast and honest like everything else on ProxyNest.
Every tool runs in your browser, shows its work, and never asks for an account. If a tool would be useful to you, tell us and we will consider adding it.
