NetLimiter is a Windows internet traffic monitoring and control tool that lets you monitor network activity and manage the bandwidth used by individual applications or connections. It can set download and upload speed limits, block connections, and provide both real-time and historical traffic statistics.
Key Features
-
Network Monitor: View applications communicating over the network, connection details, and current transfer rates.
-
Bandwidth Limiter: Set download and upload speed limits for individual applications, connections, or groups.
-
Traffic Statistics: Track network usage over time with detailed application-level traffic statistics.
-
Connection Blocker: Create rules to allow or block selected applications and connections.
-
Rule Scheduler: Automatically apply bandwidth or connection rules at specified times.
-
Traffic Charts: Visualize network activity and bandwidth usage in real time.
-

-
Network Tools: Provides additional information such as WHOIS and traceroute.
-
Remote Administration: Manage NetLimiter settings remotely when configured for supported environments.
User Interface
NetLimiter uses a straightforward Windows interface that lists applications and their network activity. Transfer rates, limits, rules, and traffic statistics can be viewed from the main window, while additional tools provide charts and detailed connection information.
The large amount of network data and available rule options may take some time for new users to understand.
Installation and Setup
Install NetLimiter on a supported Windows system and launch the application with the required permissions. After startup, it automatically detects applications using network connections.
You can then configure bandwidth limits, connection rules, blocking options, and scheduled rules according to your needs. The software is available as a trial, with some features requiring a paid license.
