About User-Agent parsing
The User-Agent header is the string your browser sends to identify itself. Parsing it is necessarily heuristic— browsers deliberately impersonate each other for compatibility (Chrome's UA contains "Safari", Edge's contains "Chrome"), so this tool matches the most specific token first. Everything is parsed in your browser; nothing is sent to a server.
