Openpilot Chrome Extension (Unofficial)

Blog post: Chrome Extension for Openpilot Supported Cars (Unofficial)

Shop for cars in autotrader.com, autotrader.ca, and curbie.ca knowing which ones are supported by Openpilot.

Supported websites

The extension currently works the following web pages:

• autotrader.com/cars-for-sale/all-cars
• autotrader.ca/new e.g. https://www.autotrader.ca/new/hatchback,suv/?srt=1&make=Honda,Hyundai,Toyota
• curbie.ca/cars

Adding a new website to support

If you want to support a new website, e.g. carmarketplace.com. Add a new class CarmarketPlaceCom that implements the Website interface. Refer to the existing Website interface implementations for details.

Supported cars data source

Supported cars data is from Openpilot's README.

Comma.ai has an API that returns supported vehicle compatibility data. However, it's not as up-to-date as Openpilot's README. I used tableconvert.com to convert this markdown table from Openpilot's README into JSON.

This manual step is not glamorous. However, I could readily assign comma's API response to the compatibleCars constant if ever I decide to use it in the future.

To update the supported cars JSON:

• Copy the table in markdown format from the Openpilot README
• Convert the table markdown to JSON using tableconvert.com
• Update the cars array in supported.ts and community.ts.
• Supported car sources:
  • https://github.com/commaai/openpilot/blob/master/README.md#supported-cars
  • https://github.com/commaai/openpilot/blob/master/README.md#community-maintained-cars-and-features
