Browse as any browser or device. Per-site User Agent rules, 18 presets, custom UA strings, iCloud sync — right in Safari.

Switch your User Agent per website — right inside Safari. Browse as Chrome, Firefox, Edge, or another device: request desktop sites on iPhone, test mobile layouts on Mac, or open pages that block Safari.
