Decode browser, engine, OS, device, bot and webview signals; inspect Client Hints; spot inconsistent or reduced identifiers; and batch-analyze logs locally.

User-Agent strings can be spoofed, reduced, frozen or compatibility-shaped. This parser reports clues with caveats instead of pretending the result is cryptographic truth.
Use UA parsing mainly for diagnostics, analytics and known compatibility workarounds. For application behavior, feature detection and progressive enhancement are usually safer.
User-Agent Client Hints expose structured values in supporting browsers, but availability varies and high-entropy values have privacy implications.
