In short
Browser Feature Test is a free online tool on inputtesthub.com that checks thirty browser capabilities at once — audio, camera, WebGL, storage, sensors, sharing — and shows which are available. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.
How to use the Browser Feature Test
- The test starts on its own — no button to press and nothing to install.
- Follow the prompt in the test panel and watch the readings update live.
- Press Reset to start over with a clean slate.
About the Browser Feature Test
The Browser Feature Test checks thirty browser capabilities at once — audio, camera, WebGL, storage, sensors, sharing — and shows which are available. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Working out why a web application will not run in one particular browser.
- Checking a locked-down corporate browser before reporting a bug.
Frequently asked questions
A feature says No. Is my browser out of date?
Not necessarily. Several of these are missing by deliberate choice rather than age — Safari and Firefox both removed the Battery Status API for privacy, and iOS has never supported vibration. Check the browser's own release notes before assuming an update will help.
Are there any usage caps on the Browser Feature Test?
There is no cost and no cap. The Browser Feature Test is not a demo of a paid product, so nothing is held back or watermarked.
Does anything I enter leave my computer?
No. The Browser Feature Test runs entirely in your browser using JavaScript. Your input never reaches inputtesthub.com or any third party — open your browser's Network tab while you use it and you will see no request go out.
When would I actually need the Browser Feature Test?
Typical uses: working out why a web application will not run in one particular browser. Checking a locked-down corporate browser before reporting a bug. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Does the Browser Feature Test need an app or a driver?
No installation, no extension and no driver. The Browser Feature Test uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
