Because Kotlin interopts so well with Java, you can use any of the battle tested web frameworks like Spring (Boot) with ORM's like Hibernate. Most of these frameworks/libraries even have additional kotlin extensions to enhance the experience. Kotlin + Spring + Postgres is my default stack to do a web/api project in 2021. Super productive environment with good configuration/cloud/di/orm support and a huge ecosystem of available libraries.
