I feel like I owe everyone a thank you, and an apology. A thank you because the Carfree webapp started seeing steady use earlier than I expected. This resulted in one of the APIs I was using, specifically one to do an approximate geolocation based on IP address, to reach a request limit. This in turn, caused the Carfree webapp to fail. So, I thank you, and apologize for that.
I’ve switched to a new IP geolocate provider, and the webapp *should* see more stability for a while. At least, where geolocation is concerned.
So, please do continue planning trips with it, and by all means get in touch with me if you have any questions about or ideas to improve the Carfree webapp.
