Free Screen & Device Tests Online | Private Browser Diagnostics
About DeviceKit
DeviceKit is a free, privacy-first toolkit for testing your screen and devices directly in the browser. There is nothing to install and no account to create. You open the site and run diagnostics on the hardware in front of you in seconds.
Everything runs locally in your browser, so your diagnostics stay on your own machine rather than being sent off somewhere. The toolkit covers the checks people actually need when sizing up a device, including screen and dead-pixel tests, plus camera and microphone checks, so you can confirm a new or used device works before you rely on it.
It is a handy, no-friction option for anyone buying a used phone or laptop, troubleshooting a hardware issue, or just wanting a quick sanity check on their gear.

Worth the price of admission
DeviceKit solves a real problem for me without making a fuss about it. What stands out is how little babysitting it needs. It handles the boring parts so I can focus on the work that matters. Recommending it to people in a similar spot.
Does the job, a few gripes
DeviceKit has quietly become part of my daily flow. What stands out is how little babysitting it needs. Genuine strength is that it gets out of the way and lets me work. The docs could go a bit deeper in places. Recommending it to people in a similar spot.
Exactly what I needed
Tried DeviceKit on a side project first, then rolled it out everywhere. What stands out is how little babysitting it needs. The output quality holds up better than I expected. Worth the price for what I get out of it.
Exactly what I needed
Onboarded the whole team to DeviceKit in an afternoon. It does what it says, which is rarer than it should be. It has shaved real time off my week. Would sign up again without thinking twice.
It just works
Started using DeviceKit casually, now it is pinned in my dock. It handles the boring parts so I can focus on the work that matters. Glad I made the switch.

Good, with a few caveats
Came to DeviceKit after getting frustrated with what I had before. It is the rare tool that got better the more I used it. I expected to churn off it in a week and I am still here. Not perfect, but the rough edges are minor.
Bought it for one feature, stayed for ten
Picked DeviceKit for the price, stayed for the quality. Nothing flashy, it simply pulls its weight every day. It earns its place in my stack.
Solid but not perfect
Started using DeviceKit casually, now it is pinned in my dock. Performance has been steady even when I lean on it hard. It took me a bit to get comfortable with it. It earns its place in my stack.
Finally something that fits
Three months of DeviceKit later, here is what holds up. The output quality holds up better than I expected. It just works, day after day, without surprises.
Quietly excellent
Found DeviceKit on a Reddit thread and I am glad I clicked. Performance has been steady even when I lean on it hard. Setup was painless and I was productive the same day. Easy yes for anyone weighing the same trade offs.
Powerful once it clicks
Started using DeviceKit casually, now it is pinned in my dock. Performance has been steady even when I lean on it hard. Pricing could be a little simpler to reason about. Glad I made the switch.
