OBD-II standard
OBD-II has been mandatory for cars since 1996. We work with any ELM327-compatible adapter and read Mode 01 (live data), Mode 03 (DTC), Mode 04 (clear DTC), Mode 09 (VIN). No vendor lock-in to a specific adapter brand.
Read DTC codes and live PIDs from an OBD-II adapter over Bluetooth.

Learn moreYou own the car and want to know what "Check Engine" means before the shop. Quick sessions from the phone, per-car history, plain-language AI explanations.
Personal tierYou own or work in a small garage. Web panel with concurrent sessions, branded PDF reports for customers, DTC library with explanations.
Pro tierYou run 10 to 500+ vehicles. Roles and permissions, automatic alerts on critical DTCs, cross-vehicle comparison, exportable reports.
Fleet tierPair an OBD-II adapter over Bluetooth and get instant DTC decoding, trip history, live telemetry charts and an AI co-pilot that explains causes and suggests next steps.
Works with every common ELM327 and STN chip family across all five OBD-II protocols. Buy any adapter listed below and it just works.
| Adapter chip | Transport | OBD-II protocols | CAN-FD | Notes |
|---|---|---|---|---|
| ELM327 v1.5 (clone) | Bluetooth SPP | All 5 (ISO 9141-2, KWP2000, J1850 PWM/VPW, CAN 11/29-bit) | No | Cheapest and most common option. Good for vehicles up to 2018. |
| ELM327 v2.1 / v2.2 | Bluetooth SPP | All 5 (ISO 9141-2, KWP2000, J1850 PWM/VPW, CAN 11/29-bit) | No | Recommended for 2008+ vehicles. Best price/quality ratio. |
| STN1110 (OBDLink MX+, OBDLink LX) | Bluetooth SPP | All 5 + CAN-FD (ISO 15765-4) | Yes | Best choice for 2020+ vehicles with CAN-FD buses. |
| Vgate iCar Pro | Bluetooth SPP | All 5 (ISO 9141-2, KWP2000, J1850 PWM/VPW, CAN 11/29-bit) | No | SPP diagnostics only; BLE mode unsupported. |
| Genuine ELM327 (Elm Electronics) | Bluetooth SPP | All 5 (ISO 9141-2, KWP2000, J1850 PWM/VPW, CAN 11/29-bit) | No | Reference implementation — all documented SAE J1979 Mode 01–09 services supported. |
Open OBD-II standard, eight specialized AI agents, and a microservice platform — here is what is under the hood.
OBD-II has been mandatory for cars since 1996. We work with any ELM327-compatible adapter and read Mode 01 (live data), Mode 03 (DTC), Mode 04 (clear DTC), Mode 09 (VIN). No vendor lock-in to a specific adapter brand.
Diagnostics produces the overall assessment. OBD-reader talks to the adapter. DTC-analyzer explains codes. Prediction estimates failure risk. Report-generator builds the PDF. Recommendation suggests actions. Chat handles questions. Fleet management agent assists operators with multi-vehicle oversight.
We poll standard PIDs (RPM, speed, coolant temp, MAF, throttle, load, lambda) at up to 5 Hz. Charts render client-side without lag. Manufacturer-specific Mode 22 PIDs unlock deep analysis.
The web client talks only to a single entry-point API gateway. The gateway calls internal TypeScript services over encrypted internal RPC. AI agents subscribe to events via an event bus. A managed SQL database stores data, each service owns its own schema.
Industry-standard authentication with refresh tokens. Passwords are stored as salted one-way hashes, never in readable form. Internal services are reachable only through the single entry point over an encrypted channel. ECU write commands (Mode 04 clear DTC) require explicit confirmation. Audit log for every account change.
Android 7 and newer. Gasoline and diesel cars with an OBD-II port (1996+). ELM327 v1.5+ adapters over Bluetooth Classic SPP. Optional WiFi-OBD for emulators. Web panel — any modern browser.
