# dubbo vs ktor

dubbo and ktor share 6 technologies: tomcat-embed-core, javax.servlet:javax.servlet-api, jakarta.servlet:jakarta.servlet-api, compiler, io.micrometer:micrometer-core, and org.slf4j:slf4j-api. dubbo is written in Java and ktor in Kotlin.

- [apache/dubbo](https://seerepo.com/r/apache/dubbo): The java implementation of Apache Dubbo. An RPC and microservice framework.
- [ktorio/ktor](https://seerepo.com/r/ktorio/ktor): Framework for quickly creating connected applications in Kotlin with minimal effort
