User-Agent Parser

Parse User-Agent

Analyze browser, operating system, rendering engine, device type, architecture and common bots.

User-Agent String

Modern Chromium-based browsers can intentionally hide exact OS, device and minor-version details. When detected, the parser marks those values as reduced instead of guessing.

Parsed Result

— Browser / Client

— Operating System

— Device Type

— Device Model

No Bot / Crawler

— Rendering Engine

— Architecture

— UA Detail

About

The XAVERT User-Agent Parser analyzes common User-Agent strings directly in your browser.

Main Features

Detect modern and legacy browsers, webviews and HTTP clients.
Identify operating systems, device types and common device models.
Detect common search, social, SEO and AI crawlers.
Identify rendering engine and architecture where reliably exposed.
Recognize Chromium User-Agent Reduction and frozen platform fields.
Use User-Agent Client Hints for additional local details when you explicitly analyze your current browser and the API is supported.
Copy or download the generated analysis report.

Important Limitation

User-Agent strings can be reduced, frozen or spoofed. The parser reports the information that is actually exposed and avoids inferring hidden details when the string does not support a reliable conclusion.

Privacy First

User-Agent parsing and optional Client Hints analysis happen locally within your browser. Your input and detected browser details are never uploaded, transmitted, shared or stored on any server.
