Tool
Proxy checker
Paste a proxy and see whether it answers, how fast, which protocols it speaks and which exit address it shows.
Free tools
Tools, no strings.
Four small tools for people who work with proxies. Each one is a plain form: it works with JavaScript off, needs no account, and keeps nothing you type. Public pages on this site set no cookie, and the privacy page lists everything the site stores.
Tool
What is my IP
The address and the headers your connection shows to a website. Load it through a proxy to see the exit instead.
Tool
Bandwidth cost calculator
How many gigabytes a crawl needs and what it costs per GB, next to what the same job costs on a static or thread-based proxy.
Tool
Proxy string converter
One proxy line, every format: host:port:user:pass, URL form, curl, Python, Node and environment variables.
Need the proxies themselves? Residential per GB that never expires, ISP and datacenter static IPs by the month, rotating IPv6 by the thread. A random key is the whole account; pay in crypto or by card.
