Show HN: Engine.codes – read OBD-II codes in the browser, no app, no cost

Most OBD scanners hide the basics behind pricey hardware or subscriptions. My free, browser-only OBD-II tool lets you plug in a $10 BLE dongle, tap Connect, and instantly:

* auto-detect your VIN

* read Mode 03 / 07 trouble codes

* keep your data private—no cookies, no VIN tracking

Give it a spin and let me know which BLE adapters work (or don’t) for you!

Thanks for the feedback. I removed the source link now. If you're interested in the OBD2 client source, it's self-contained in the Javascript sent to the browser.
