Free Tools for Developers & Scrapers

A growing toolkit to test proxies, convert requests, validate selectors and decode user-agents — all free, most running entirely in your browser with no signup.

Available tools

Proxy Checker: test any proxy for real exit IP, country, ISP, latency and anonymity. Supports HTTP, HTTPS and SOCKS5.
cURL to Code Converter: turn a curl command into Python, Node.js, PHP or Go.
XPath & CSS Selector Tester: test selectors against your own HTML and see matched nodes.
User-Agent Parser: decode a user-agent into browser, OS, engine and device.

Built by a proxy network

These tools come from the team behind ProxyGen's residential, mobile, ISP and datacenter network across 195+ countries. They are free, require no account, and the client-side tools never send your input to a server.
