Naughty Keyboard is a tool for testers and developers. One shortcut types the next awkward value into the field in front of you: null, a trailing space, a zero-width space, 30.02.2026, =1+1, a name of 65 535 characters. They are the values real users and real data produce, and a form you only ever tried with "John Smith" has never met them. Every value comes with what it usually breaks and what a correct application does instead. When one of them breaks something, one more shortcut copies...

It’s written in plain “vanilla” JavaScript, it leverages the IntersectionObserver API, it supports...

...It is a relative value used for determining the lowest latency server for performing the actual speed test against. Speedtest CLI brings the trusted technology and global server network behind Speedtest to the command line. Measure internet connection performance metrics like download, upload, latency and packet loss natively without relying on a web browser. Test the internet connection of your Linux desktop, a remote server or even lower-powered devices such as the Raspberry Pi with the Speedtest Server Network. ...

Ethr is a cross-platform network performance measurement tool written in golang. The goal of this project is to provide a native tool for comprehensive network performance measurements of bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems. Ethr takes inspiration from existing open-source network performance tools and builds upon those ideas. For...

Integrated packet generator and sniffer for Ethernet, but also works with blocks of data over TCP connection. Enables you to use scripts for automated testing, monitoring, imitating of various network objects, creating custom network tools.
