TestHub360 — Free Online Device Tests - 8 browser-based testing tools. No signup. 100% private.

by•
TestHub360 is a collection of 8 free, browser-based device testing tools — mic test, keyboard test, webcam test, speaker test, mouse test, CPS test, dead pixel test, and screen recorder. What makes it different: → Zero data collection — everything runs client-side in your browser → No account, no signup, no email → Works offline once loaded → NKRO keyboard testing, mouse DPI tracking, CPS timer modes (1s–60s), fullscreen dead pixel cycling, and WebM screen recording with audio

What inspired me to build TestHub360 was a simple frustration: every time I joined a Zoom call, I'd scramble to figure out if my mic and webcam were working. Existing testing sites either required downloads, pushed ads in your face, or collected your data. I wanted something that just works — open a page, run a test, get an answer. No accounts, no upsells, no data leaving your browser. Eight tools later (mic, keyboard, webcam, speakers, mouse, CPS, dead pixel, screen recorder), it's become the device testing hub I wished existed. Every tool uses your browser's built-in Web APIs — the same ones Zoom and Discord use — so if it works here, it'll work there. Would love feedback from the PH community. What tools would you add next?

This is super handy for quick diagnostics, love that nothing leaves the browser. One thing that would make it even better: add an export or share option for the screen recording, since right now it seems like you can only save it locally. Being able to grab a shareable link or upload straight to cloud storage would save a lot of time when I'm sending clips to teammates for bug reports.

 Great feedback — you're right that the current flow just downloads a WebM file locally. For bug reports to teammates, that's not ideal.

Here's what's coming soon:

  1. Shareable link — after recording, generate a temporary URL so teammates can watch instantly

  2. Upload to Google Drive / Dropbox — one-click export after recording stops

  3. MP4 export — WebM isn't universal, so a built-in converter would help compatibility

The privacy-first approach stays the same — shareable links would be encrypted and auto-expire after 7 days. No permanent cloud storage unless you choose it.

Appreciate the suggestion — this helps prioritize the roadmap!

Tried the dead pixel test earlier and it loaded super fast without me signing up for anything, which honestly felt kind of rare. The fullscreen color cycling was perfect for actually spotting issues on my monitor.
