How to use this tool

Paste a public test User-Agent string. Inspect Bowser labels, exact observed substrings and limited bot-name heuristics; no crawler identity is verified.

When not to use it

User-Agent strings can be spoofed and may be reduced by privacy features; do not use them for security decisions.
