    Best Proxy Providers

    This tool lets you check if your proxies actually work and how they perform. It supports HTTP, HTTPS, SOCKS4, and SOCKS5, and shows basic info like response time, location, and provider. You can test one proxy or paste a list of up to 100 at once, and it accepts formats such as IP:PORT, IP:PORT:LOGIN:PASSWORD, and LOGIN:PASSWORD@IP:PORT.

    Checks run in real time, so you instantly see whether a proxy is online, how fast it is, and where it's located. The tool can also recognize the proxy type, such as datacenter, residential, mobile, or ISP, and show the hosting provider when that information is available. Speed is labeled as good, medium, or weak, so it's easy to understand results at a glance.

    It's useful when you want to double check a proxy before using it for scraping, automation, marketing tasks, or regular browsing. The bulk option saves time if you work with larger lists and need to sort working proxies from dead ones. Just paste your list and run the test.

    Frequently Asked Questions

    A proxy checker is a tool that tests proxy servers to verify their availability, speed, location, and anonymity level. It helps you ensure your proxies are working correctly before using them.

    Our checker supports three formats: IP:PORT, IP:PORT:LOGIN:PASSWORD, and LOGIN:PASSWORD@IP:PORT. Both IP addresses and hostnames are supported.

    You can check up to 100 proxies at once using the bulk check mode. Simply paste your proxy list, one per line.

    Ping measures the response time of a proxy server in milliseconds. Lower ping means faster connection. Green indicates good speed, orange is medium, and red means slow.

    We support HTTP, HTTPS, SOCKS4, and SOCKS5 protocols. You can specify the protocol when adding a single proxy or let the checker detect it automatically.

    Green (Good) means the proxy is fast and responsive (under 200ms). Orange (Medium) indicates moderate speed (200-500ms). Red (Weak) means the proxy is slow (over 500ms).

    Yes, our proxy checker is completely free to use. There are no hidden fees or premium features required.

    Yes, you can provide login and password credentials for proxies that require authentication. Passwords are hidden in the results for security.

    Results reflect real-time proxy performance at the moment of checking. Proxy speed and availability can vary over time, so we recommend rechecking periodically.

    HTTP proxies handle web traffic, HTTPS adds encryption, SOCKS4 supports TCP connections, and SOCKS5 adds authentication and UDP support. SOCKS5 is the most versatile protocol.
