DevSpoofer: Geo & Device

Spoof Geolocation and Device Profile (User-Agent) seamlessly on the active tab.

DevSpoofer is a lightweight and powerful tool designed for developers, QA testers, and web designers to seamlessly mock their Geolocation and Device Profiles directly within the active browser tab. Key Features: 📍 Real-time Location Spoofing: Input any latitude/longitude or simply paste a Google Maps URL. The extension accurately extracts the precise pin coordinates and safely overrides the HTML5 Geolocation API (navigator.geolocation). 🕹️ Nudge Controls: Move your mocked location smoothly in real-time (North, South, East, West) without reloading the page. Perfect for testing location-tracking or delivery applications. 📱 Device Profile & User-Agent Mocking: Quickly switch between Default, Android, iOS, Windows, and macOS profiles. 🌐 Network-Level Override: DevSpoofer automatically intercepts and modifies HTTP headers (such as User-Agent) and removes modern client hints (Sec-CH-UA) using Manifest V3 DNR rules, ensuring backend servers see exactly the device you are spoofing. ⚡ Minimalist UI: A clean, modern interface that stays out of your way and provides real-time status feedback. Whether you're debugging location-based services, testing responsive mobile web views, or checking geo-restricted logic, DevSpoofer makes it incredibly easy and fast. No external servers involved—all data stays locally on your device.
