Live OBD-II data in your browser
Connect a Bluetooth LE ELM327 adapter to read live data from your car, decoded with the community OBDb signal definitions. Everything runs on this device; nothing is uploaded.
Plug the adapter into the OBD port, switch the ignition on, then choose the adapter from the list, which shows likely OBD adapters. Only Bluetooth LE adapters work in a browser.
Web Bluetooth isn't available in this browser. It works in Chrome and Edge on desktop and Android. On iPhone and iPad, use the Bluefybrowser.
Try it without a car
The demo replays real responses captured by the OBDb community, animated by a simulated drive.

Don't operate while driving. Pull over, or let a passenger use the scanner.
