User Agent Parser details

Parse browser User-Agent strings into browser, OS, device type, and rendering engine. User Agent Parser is now a native Toolars workspace for local browser, OS, device, and engine inspection.

Overview

User Agent Parser analyzes browser and crawler User-Agent strings to detect browser name and version, operating system, device type, rendering engine, and raw string context with dependency-free rules. The native Toolars workspace migrates the Aixtral parser into local controls, keeps User-Agent strings in the browser, identifies bots and common mobile/tablet cases, and gives QA and support teams copy-ready environment summaries.

Local User-Agent parsing model

LocalInputs are processed in the browser by the native Toolars workspace and are not uploaded for conversion.

ReviewParser limitations stay visible because User-Agent strings can be spoofed or omit reliable browser signals.
