Evaluating Otonomo competitors?

Smartcar is a developer-friendly alternative to vehicle data marketplaces like Otonomo.

Is Smartcar right for you?

If you’re looking to purchase data sets for mapping, traffic management, parking solutions, or media management then Otonomo may be a good fit for you. This type of vehicle data may help you determine where to place a new retail location, which billboard ads to run, or how to route your fleet more efficiently.

But if you want to integrate apps or services with connected vehicles, then Smartcar is the developer platform for you. With Smartcar, you can easily retrieve data from cars and even trigger actions through our simple and secure API. Mobility businesses of all kinds use our APIs to track vehicle location, verify mileage, share digital car keys, manage EV charging, and much more.
