Alternative framework to Google map API which is "offline"

Question

I need to develop a feature where I need to show the directions between two zipcodes on a map offline. Is there any such framework which can display directions between two zipcodes ? I tried Highmaps, but it doesn't show directions between tow point. I looked at the below apis too. But I think they cannot work offline. Thanks in advance

Try hosting your own open-source instance, for example Graphhopper.
