jProxyChecker is an application developed in Java that gives you the possibility to create a list with proxies to find out if they're still working and how strong the level of anonymity is.

It's designed not only for experienced users, but also those curious enough to find out how to apply a proxy configuration when connecting to the Internet.

It adopts a user-friendly interface made from a large window with a simple design and neatly organized structure, where you can add a new proxy to the list by specifying the IP address and port number.

It's possible to add as many proxies as you want, remove any entry from the list if you change your mind, import a list of proxies from an external file (with "ip:port" or "ip port" format), as well as ask the utility to run checkups on all proxies at the same time.

Once the scanner is over, you can view the status, IP address, port number, host name, city, country, delay time and level of anonymity of each entry. The anon level is determined by visiting a PHP script with the current testing proxy, so this task may take a while. All proxies that are still working (alive) can be exported to file.

The entire program is wrapped in an executable .jar file that can be saved anywhere on the disk or stored on a removable storage unit, in order to run jProxyChecker on any computer with Java. It doesn't add new entries to your system registry or create files on the disk.

It worked smoothly in our tests, without causing the OS to hang, crash or indicate errors. It didn't put a strain on the computer's performance, using low CPU and RAM. Thanks to its approachable interface and settings, jProxyChecker can be easily used for monitoring proxies.
