Idun Agent Platform wraps your agent code into a FastAPI service through framework-specific adapters. You write your agent in the framework you prefer, and the engine handles streaming, checkpointing, guardrails, and observability through a unified API. Each adapter implements a common BaseAgent protocol. Your clients talk to the same HTTP API regardless of the underlying framework.

​
Supported frameworks

LangGraph

Graph-based agents with full AG-UI streaming, checkpointing (in-memory, SQLite, PostgreSQL), and CopilotKit support. Has the most complete feature coverage of the supported frameworks.

Google ADK

Google’s Agent Development Kit for Gemini-powered agents. Supports session and memory services through in-memory, Vertex AI, or database backends.

How adapters work

Under the hood, the engine loads your agent through the adapter specified in your configuration. This gives you:
  • Unified API: All agents expose the same HTTP endpoints for invoke, streaming, and chat.
  • Shared platform features: Observability, guardrails, MCP tools, and memory work the same way across frameworks.
  • Consistent deployment: Run agents through the Idun Agent Engine standalone or managed by the Agent Manager.
You select the framework when configuring your agent:
In the agent creation wizard, Step 1 asks you to select a framework:
  • LangGraph: Build stateful, multi-actor agents with LangGraph
  • Google ADK: Build agents with Google’s Agent Development Kit Select framework in the agent creation wizard
Step 2 configures framework-specific settings such as the graph definition, port, and host.Framework-specific settings in step 2
