About What Is My Browser

What Is My Browser is a no-nonsense utility for engineers and technical marketers. Detect your browser, engine, OS, screen, language and feature support. Give it your session and it returns a metric breakdown — no sign-up, no ceremony.

There is nothing to enter — the check reads what your browser and connection already expose and reports it back clearly.

What Is My Browser is free to use with no account required. Signing in adds saved history, favourites and higher daily limits, and unlocks the other 311 tools on the platform.

Anything that can be computed in your browser is — nothing is uploaded unless the job genuinely needs a server.

Why teams use it

Stop paying for a single-purpose tool

What Is My Browser is one of 312 tools on the same account. One subscription replaces the handful of point solutions most developer teams end up stacking.

Get to the decision faster

The output is structured around what you will do next, not around what was easiest to measure. Less interpretation, fewer meetings.

Share results without a screenshot

Export to PDF or CSV, or send a link. Clients and colleagues see the same thing you do, formatted properly.

Works the same on every device

The full workspace — including tables and exports — works on a phone, a tablet and a 4K display without a separate app.

Free accounts get 25 tool runs a day across the whole platform. Starter raises that to 250, Professional to 1,500, and Business to 6,000. Enterprise is unlimited.
