Parse a user agent string into its parts: browser and version, rendering engine, operating system and version, device type (mobile, tablet or desktop) and whether it looks like a bot or crawler. Uses an ordered pattern table (Edge before Chrome, Chrome before Safari). User agent strings can be spoofed, so results are best-effort, not proof. Source: https://hopi.co.uk/user-agent-parser/
