What are the limits of User-Agent Decoder?
Heuristic local token recognition, not a definitive device identity. Reduced, spoofed and embedded app strings may omit details; unknown values stay unknown. Does not fingerprint visitors or collect client hints. Paste one string per line, up to 200; browser value is read only after an explicit button click. Text input: 5 MB total. XML external entities and includes are disabled. No automatic local storage. Reports summarize the selected result; CSV/JSON retain complete records.
