User-Agent Parsing for Analytics Debugging
When analytics show something odd, the user-agent often holds a clue. Parsing it speeds up the investigation.
Segment and investigate
Parsing UA strings from logs lets you group sessions by browser, OS or device and spot patterns — a bug that only hits one browser, or traffic from an unexpected client.
Spot bots and anomalies
Unusual or malformed UA strings can flag automated traffic. Parsing makes those stand out from genuine browser sessions.
