What NetLimiter is

NetLimiter is Windows software for monitoring internet traffic and controlling bandwidth on PCs. It can set maximum transfer speeds for an entire machine, applications, users, or individual connections, and adjust bandwidth priority. Real-time monitoring shows application traffic moving to and from the internet or other networks with traffic charts. Connection Blocker rules can stop selected applications from connecting, with an interactive prompt for creating rules as connections occur. Filters can use application paths, domain names, IP ranges, or users; quotas can trigger speed limits or blocker rules. Detailed traffic statistics are stored locally for retrospective analysis, with unlimited historical retention. NetLimiter can remotely control other machines where it is installed, supports VirusTotal checks, and offers an API for third parties. The maker says data is not sent to or stored outside the installed machine, although the software connects online for updates, license registration, and VirusTotal checks. It is listed for Windows 7, 10, 11, and later, and includes a 28-day trial.

Who it suits

It suits Windows users who need per-application bandwidth controls, connection blocking, traffic charts, and long-term local statistics. Administrators can also manage other installed machines remotely.
