Hi every one ✋, now i start to develope and convert my old backend stuff from asp.net to ktor , but one thing i missed about ktor , it is available to deploy the web app into any hosting service like histinger ... etc , because i dont find any information about this except deploy it to heroku and i dont need it "so expensive" , any information about it , many thanks in advance 😀.

Ktor by itself it’s just a web framework, you can deploy your service everywhere JVM is supported. Btw, Heroku has a free plan as well for personal projects or non-commercial apps.
