Koog is a JetBrains framework for building AI agents on the JVM, written in Kotlin and usable from Java across backend, Android, iOS, JVM, and browser targets. Topics indicate support for multiple LLM providers (OpenAI, Anthropic, Ollama), MCP, multi-agent systems, and integrations with Ktor and Spring.

You want a fault-tolerant, enterprise-oriented agent framework that runs anywhere the JVM or Kotlin multiplatform does.

Use it to

  • Build LLM agents in Kotlin or Java
  • Run agents across backend, Android, iOS, and browser targets
  • Wire multiple providers like OpenAI, Anthropic, and Ollama
  • Compose multi-agent systems with MCP support
  • Embed agents into Ktor or Spring services

For Kotlin and Java developers building production AI agents
