User-Agent Parser & Device Detector

Paste any user-agent string to identify the likely browser, version, operating system, engine, device type, architecture hints, and whether it looks like a bot. Good for QA, analytics debugging, support tickets, and log triage.

Client-side only No user-agent strings leave your browser.
Support-friendly Copy a clean human summary in one click.
Fast heuristics Useful labels without any dependency or API.
UA
What it catches

Chrome, Safari, Edge, Firefox, Samsung Internet, Opera, bots/crawlers, desktop/mobile/tablet, and major OS families.

⚠
Keep in mind

User-agent detection is heuristic. Browsers can spoof strings, and modern platforms are slowly reducing UA detail in favor of Client Hints.
