# dubbo vs Signal-Server

dubbo and Signal-Server share 9 technologies: JAX-RS, jakarta.servlet:jakarta.servlet-api, jakarta.validation:jakarta.validation-api, commons-logging, micrometer-bom, io.micrometer:micrometer-core, org.slf4j:slf4j-api, OpenTelemetry, and io.micrometer:micrometer-registry-otlp. Both are written in Java.
