Overview
Inspect this browser's user agent, language, screen, viewport, and timezone locally.
Supported input
The current browser's standard navigator, screen, viewport, and timezone values. No input or permission prompt is required.
Output details
A local snapshot of browser-reported values. Browser, OS, and device labels are estimates from the user agent string.
Limitations
- User agents can be reduced or spoofed; estimates do not reliably identify a device or exact software version.
- Screen and viewport dimensions are CSS pixels, not necessarily physical display resolution. Refresh after resizing.
- The cookie flag does not prove third-party cookies or cookies for every site are allowed. This page does not set a test cookie.
- This is browser information, not an IP lookup or connectivity test.
Privacy and security
This tool runs entirely in your browser. Your input is never uploaded to our servers.

Frequently asked questions
Why can my browser or version be wrong?
The labels come from user-agent text. Browsers can reduce that text, and extensions or settings can change it. Use feature detection in application code.
What does Cookies enabled mean?
It is the navigator.cookieEnabled flag, not a test of a specific cookie, third-party access, or your advertising consent.
Is this information sent to Small Tools?
The tool reads and displays its snapshot locally. Copy writes it to your clipboard only when selected; ordinary site hosting, analytics, and advertising requests remain separate.
Why does the viewport differ from the screen?
The viewport is the space available to this tab. Browser chrome, window size, zoom, and device settings can make it smaller than the screen.
