Questions & Answers

As answered by people managing HTML PDF API and TestHub360.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

TestHub360's answer:

Astro — static site framework React — interactive tool components Tailwind CSS — styling and dark mode Web APIs — MediaDevices (mic/camera), KeyboardEvent, PointerEvent, Web Audio API, Fullscreen API, MediaRecorder + getDisplayMedia (screen recording) Cloudflare Pages — hosting and global CDN

Who are some of the biggest customers of your product?

TestHub360's answer:

TestHub360 is currently used by remote workers, students, and gamers worldwide. As a free, no-signup tool, individual user data is not tracked — so we don't have specific company names to share.
