About Ktor
Ktor is an asynchronous web framework for building servers and clients in Kotlin, developed by JetBrains. It is designed to take full advantage of Kotlin's coroutines for highly concurrent, non-blocking I/O, making it suitable for building efficient microservices and REST APIs.
Ktor uses a plugin-based architecture where functionality such as authentication, serialization, logging, and routing is added modularly. It supports both server-side and client-side HTTP operations and can be deployed on the JVM or compiled to native code via Kotlin/Native. Ktor is the natural choice for Kotlin developers building backend services, competing with Spring Boot and Micronaut in the Kotlin server-side ecosystem.
