# Koog - **Website:** - **Primary alias:** `koog.ai` ## Description Koog is an innovative, open-source framework developed by JetBrains, tailored for building AI agents within the JVM ecosystem. It offers a superior development experience for both Kotlin and Java developers, featuring an idiomatic, type-safe Kotlin DSL and intuitive builder-style Java APIs. Koog empowers developers to create agents that can operate across multiple platforms including JavaScript, WebAssembly, Android, and iOS via Kotlin Multiplatform. The framework includes various agent types, such as basic agents with predefined strategies, functional agents that allow for custom logic through lambda functions, and graph-based agents that implement workflows as strategy graphs. Koog also introduces planner agents that build and execute plans dynamically. The framework’s extensive tools and features enable interaction with external data sources and support advanced functionalities like history compression, structured output generation, and real-time streaming APIs. With integrations for popular frameworks like Spring Boot and Ktor, and observability through OpenTelemetry, Koog elevates AI development to new heights, making it a critical tool for modern developers. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Artificial Intelligence and Machine Learning _(under Computers Electronics and Technology)_ ## Links - [github](https://github.com/JetBrains) ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/id9haDjEUv/w/64/h/64/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1789096169849) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Electric Violet | #9f39f8 | accent | | Sherpa Blue | #005454 | dark | | Gorse | #fefc4f | light | ## Fonts - var(--md-text-font-family) — asset _(custom)_ - var(--md-text-font-family) — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
