NetBalancer
NetBalancer monitors computer network traffic and lets users control it with process priorities, limits, and rules.
What NetBalancer is
NetBalancer monitors computer network traffic and lets users control it with process priorities, limits, and rules. Download and upload settings can be applied per process, while network adapters can be managed separately. Rules may target adapters, IP addresses, ports, protocols, and time periods. The application displays active connections, traffic charts, and data usage statistics, with unlimited historical data retention for one monitored device. A command-line tool and web APIs support programmatic traffic management. Its Sync service can synchronize and remotely manage one or more computers running NetBalancer. The unregistered version provides monitoring only and does not include priorities or rules. A 14-day trial enables all application functionality, while Sync has a separate 30-day unlimited trial. The listed NetBalancer App and Sync plan costs $49.95 a month and includes one PC, one year of updates, and one year of Sync service. Renewal is listed at $34.95 a month. The software is described for Windows 7, 8, 10, and server variants, with native x64 support. NetBalancer is based in Chisinau, Moldova, and offers free purchase support.
