MultiProxy is an application that protects your privacy online and speeds up downloads. It is capable of updating the proxy list, and comes equipped with several configuration options.
The interface is based on a small window with a plain and simple layout, where you can view the connection status, set the frame to stay on top of other windows, as well as check all proxies and update the proxy list.
As far as program settings are concerned, you can establish a port to accept connections from, specify the maximum number of simultaneous connections, as well as change the default timeout (in seconds).
In addition, you can ask MultiProxy to connect via anonymous or non-anonymous proxies only (instead of all responding proxy servers), test anonymity by connecting back to the computer on a specific port, as well as to select the next server by various criteria (random, next fastest available server, next available one, or rotate at a specific time interval).
The application can be set to start minimized, automatically sort the proxy list by speed, and to maintain fixes proxy/IP per website.
MultiProxy is very light on the system resources, using a minimal amount of CPU and RAM. It has a good response time and works smoothly, without causing the OS to hang, crash or pop up error dialogs. We haven't come across any issues in our tests. Unfortunately, MultiProxy has not been updated for a long tinme.
