WiFi Analyzer helps inspect Wi-Fi networks, signal details, and wireless connection information.
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.
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.
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.
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.
