Diagnose the car. Keep the scanner optional.

OpenAuto is built for the eighty-percent case first: VIN decoding, trouble-code explanations, factory maintenance timing, recall lookup, repair cost framing and AI symptom diagnosis — all in the browser, with no hardware required.

"The scanner is optional. The insight isn't."

Most diagnostic tools assume you own hardware before you extract any value. OpenAuto inverts that assumption: the browser-only tier is genuinely useful on its own. Garage context layers on top. Scanner hardware layers on top of that. Each layer compounds the one below it, but none are required to reach the door.

Open the app. Decode the car.

No login. No hardware. No friction. Try the public workshop first — the scanner bench is always there when you want deeper context.
