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