As answered by people managing TestHub360 and Xnapper.
TestHub360's answer
TestHub360 is a free, browser-based device testing suite that runs entirely client-side — your mic, camera, and keystroke data never leaves your browser. Unlike competitors that show ads inside tools, require downloads, or collect user data, TestHub360 is 100% private and works instantly in any modern browser with zero setup.
TestHub360's answer
Competitors like OnlineMicTest or KeyTest offer one or two tools with ads and data collection. TestHub360 bundles 8 tools (mic, keyboard, webcam, speakers, mouse, CPS, dead pixel, screen recorder) into one site — all free, all ad-free, all private. No account needed. No downloads. Just open a page and test.
TestHub360's answer
Remote workers who need to verify their mic and webcam before a Zoom call. Gamers testing keyboard NKRO, mouse buttons, and click speed. IT support staff diagnosing hardware issues for colleagues. Content creators verifying audio and video gear before recording. Anyone who needs a quick answer about whether their hardware works.
TestHub360's answer
Every time I joined a video call, I'd scramble to check if my mic and webcam were working. Existing testing sites either required downloads, pushed ads inside the tools, or collected data. I wanted something that just works — open a page, run a test, get an answer. Eight tools later, it became the device testing hub I wished existed.

No, it's taking a screenshot of the browser's content, then adding padding to the surrounding image, and letting you pick a colour for it. Screenshot Software like Cleanshot X and Xnapper have this feature built in, either as a default... Source: almost 3 years ago
