Raw user-agent
Paste a user-agent string to analyse it.Why parse user-agents?
- Debug device-specific bugs when QA reports a rendering issue.
- Verify bot traffic and filter analytics dashboards accurately.
- Segment server-side logic for legacy browsers or low-powered devices.
Why parse user-agents?
Server logs, analytics exports, and QA bug reports often include raw user-agent strings. This tool decodes them so you can understand the browser, operating system, device type, and whether the hit likely came from a crawler.
Combine it with the IP Lookup tool to build a full context around suspicious traffic or to segment issues to specific devices.
Limitations
- User-agents can be spoofed. Always corroborate with other telemetry (cookies, behaviour, IP ranges).
- New browsers ship frequently—if you spot an unknown token let us know so we can add the pattern.
- Some privacy browsers intentionally obfuscate details; we fall back to “Unknown” gracefully.
