Decision brief

Koog offers JVM-centric AI agent development with support for wide-ranging deployment environments from Kotlin.

Good fit when

  • Need JVM-based fault-tolerant AI agents across multiple platforms including Android, iOS, and web browsers
  • Development primarily in Kotlin or Java with dependency on JDK 17 and higher

Avoid when

  • Primarily working outside of JVM environments, such as pure Python or JavaScript projects without JVM support
  • Looking for an AI agent framework that does not require JDK 17 or Kotlin 2.3.10 or higher
