Limited Browser Support
Your browser does not support Web Bluetooth or WebUSB APIs. These features are available in Chromium-based browsers (Chrome, Edge, Opera) on desktop and Android.
How it works
This tool uses the Web Bluetooth API and WebUSB API to discover nearby Bluetooth and connected USB devices. Both APIs require user permission through a browser-native device chooser dialog. These APIs are only available in secure contexts (HTTPS) and in Chromium-based browsers. No device data is stored or transmitted.
Frequently Asked Questions
What are the Web Bluetooth and WebUSB APIs?
Web Bluetooth and WebUSB are browser APIs that let websites communicate directly with Bluetooth and USB devices. They require explicit user permission — you must select a device from a browser-provided dialog before any website can access it.
Why does this tool require me to click a button to detect devices?
For security, browsers require a user gesture (like a button click) before showing the device selection dialog. Websites cannot silently scan for or connect to your Bluetooth and USB devices without your explicit interaction and consent.
Which browsers support these APIs?
Web Bluetooth is supported in Chrome, Edge, and Opera on desktop and Android. WebUSB is supported in Chrome, Edge, and Opera on desktop. Safari and Firefox do not currently support either API due to security and privacy concerns.
Is it safe to let a website access my Bluetooth or USB devices?
The browser's permission model is designed to be safe — you explicitly choose which device to share. However, only connect devices to websites you trust. The connection is limited to the specific device you selected and the permissions you granted.
