Tracepanel for Java records each request of your Spring Boot or Ktor app with
its SQL, its calls to HTTP APIs, Redis, MongoDB, Kafka and RabbitMQ, its log
records and errors, and sends each trace to the agent. The agent finds the
issues and serves the panel and the console. It works in Java and in Kotlin.

```kotlin
// build.gradle.kts
dependencies {
    developmentOnly("dev.tracepanel:tracepanel-spring-boot:0.3.1")
}
```

It supports Spring Boot 3.5 and 4 with Spring MVC, and Ktor 3, on Java 17 or
later. WebFlux apps aren't supported yet.
