Pinging.net is a web tool for testing and monitoring an internet connection. It reports status for HTTP, DNS, WebRTC and the browser, and shows web ping statistics including last, minimum, maximum and average values and packet loss, with updates every 30 seconds.
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.
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.
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.
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.
The official site for NetCut, a network utility for cutting connections, and related tools including the Arcai router with built-in NetCut and Wi-Fi speed control. The site also covers NetCut-defender for protection against ARP spoofing attacks and a full-feature NetCut for Android that requires root access.
