NetBalancer is a Windows application for local network traffic control and monitoring. It allows setting download and upload priorities or limits for any process, and defining traffic rules based on time of day, protocol or application type. Deep packet inspection can monitor and limit unwanted traffic.
Wireshark is a free and open-source network protocol analyzer that lets users capture and interactively browse the traffic running on a computer network, providing deep inspection of hundreds of protocols. It runs on most computing platforms including Windows, macOS, Linux, and UNIX, and can also be built from source on other platforms.
Packet Sender is a free, open source utility for sending and receiving network packets, with support for TCP, UDP, SSL and DTLS. It includes a built-in HTTP client for GET/POST requests, panel generation, a command line interface for scripting, and runs on Windows, Mac and Linux.
CanYouSeeMe.org is a free open port check tool for remotely verifying whether a port is open or closed. It is used to check port forwarding, confirm a server is running, or detect whether a firewall or ISP is blocking ports.
Meshtastic is an open source, community-driven project that uses LoRa radios as an off-grid communication platform in areas without reliable communications infrastructure. Devices rebroadcast messages to form a mesh network without cell towers, WiFi or internet, and can be paired with a phone or computer via Bluetooth, WiFi or USB. Clients include Apple and Android apps, a web client and a Python CLI/SDK.
PortChecker is a free online tool for checking whether the ports of an internet-connected device are open or closed. It can also ping a remote server and test port forwarding settings. The tool attempts a TCP connection and reports success or a port open signal. Checking requires the computer to be reachable via a public IP address or have a port forwarded.
NETworkManager is a free, open-source tool for managing networks and troubleshooting network problems. It includes 28 built-in tools such as an IP scanner, port scanner, ping monitor, DNS lookup, remote desktop and PowerShell in a single interface. It offers profiles for organizing hosts, and no license, subscription or telemetry.
