Displaying code inspections in files

Upsource provides server-side code intelligence with its built-in static analysis engine. It supports Java, JavaScript, and Kotlin projects that use IntelliJ IDEA, Maven, or Gradle as their build system. PHP is also supported, but only with the IntelliJ IDEA build system.
