A highly configurable browser extension that spoofs the User-Agent string across Chrome, Firefox, Edge, and Opera. It overrides HTTP request headers, JavaScript navigator properties, Client Hints headers, and the navigator.userAgentData object, with per-hostname, per-tab, and randomized User-Agent options.

Use cases

• change my browser user agent string
• view mobile version of a website on desktop
• test how my site looks on different browsers and devices
• spoof user agent for a specific hostname
• randomize user agent for privacy
• override client hints and navigator.userAgentData
• set a different user agent per browser tab

When to choose

• you need consistent spoofing across headers, navigator objects, and Client Hints
• you want per-site, per-tab, or per-container User-Agent control
• you need to import/export custom User-Agent lists or randomize them
• you want a free, open-source extension available in all major browser stores

When to avoid

• you need full anonymity or anti-fingerprinting beyond User-Agent spoofing
• you need to spoof at the network level for all applications, not just the browser
• you rely on Firefox containers under Manifest v3, which is not yet supported
