User Agent Checker
See your browser's user agent string parsed into browser, engine, OS and device, plus screen, language, timezone and hardware details. The classic tool for debugging web apps.
How to use the User Agent Checker
- 1
Open the tool above — it is already running, no install or account needed.
- 2
Enter your input and adjust the options to match what you need.
- 3
Copy or download the result — everything was processed locally in your browser.
Private by design
This tool runs 100% inside your own browser using local JavaScript — your input never touches a server. That makes it instant, offline-capable in many cases, and private even for sensitive data.
