Idun Agent Platform
An open-source runtime that turns LangGraph, Google ADK, or LangChain agents into production FastAPI services.
A pragmatic, cost-saving runtime for teams tired of per-execution pricing and lock-in. It bundles everything needed for production agents in one package. Not for those wanting a managed SaaS, but excellent for self-hosters with Python expertise. For LangGraph users, it's a real alternative to LangGraph Platform with no per-node billing. If you need a managed platform or lack Python skills, look elsewhere (e.g., LangGraph Platform or CrewAI).

Skip Idun Engine if you need a fully managed SaaS platform, lack Python and agent framework experience, or require a permissive (non-GPL) license.
The GPL 3.0 license may impose copyleft obligations if you modify and distribute the engine, which could be a legal risk for some enterprises.
For self-hosting teams, Idun Engine is free (GPL 3.0), offering a cost advantage over LangGraph Platform's per-node billing. Consulting services start at €5,000 for an audit, with integration engagements up to €22,000 — cheaper than hiring a full-time engineer for a multi-month project.

About Idun Agent Platform
Idun Engine is an open-source runtime that converts LangGraph, Google ADK, or LangChain agent prototypes into production-ready FastAPI services with a single pip install. It wraps your graph with components you'd otherwise rebuild: demo chat UI, admin panel, OpenTelemetry trace viewer, PII and budget guardrails, persistent memory, MCP tool governance, and OIDC authentication. Designed for CTOs, Heads of Platform, and Principal Engineers evaluating alternatives to LangGraph Platform who reject per-node billing and vendor lock-in. Self-hosted on your own infrastructure with no per-execution markup, it keeps your code, data, and infrastructure under your control. The technical stack is Python 3.12+, FastAPI, OpenTelemetry, and multi-LLM support including Anthropic Claude, OpenAI, Google Gemini, Mistral, Cohere, and self-hosted models via vLLM. Memory persists via Postgres or Redis, and observability integrates natively with Langfuse, Phoenix, or Arize. After installing via pip, you initialize a project with three files: your graph, an agent.yaml config, and a .env, then run it locally on port 8000 with a chat UI, admin panel, traces, and a health endpoint. GPL 3.0 licensed, with full source on GitHub. What sets it apart is the all-in-one approach: it saves roughly three weeks of reinventing FastAPI streaming, OTel, multi-LLM exporters, guardrails, memory, MCP, OIDC, admin, traces, and chat UI. Compared to LangGraph Platform, it is self-hosted and runtime-agnostic, supporting LangGraph and Google ADK natively, with LangChain via an adapter. The maintenance team is based in Paris, backed by Wilco, IMT Starter, Polytechnique X-UP, and La French Tech. While the Engine is free and open-source, Idun Group's commercial model centers on consulting engagements: AI audit and scoping, integration, and a 90-day programme, each scoped during a discovery call. For teams that want a managed SaaS, this is not it; for self-hosters with Python expertise, it's a pragmatic way to production.
Behind the Verdict
Idun Engine is a strong fit for internal platform teams that have already invested in LangGraph, Google ADK, or LangChain and want to move to production without rebuilding the entire scaffolding. The single pip install packages a surprising amount: a chat UI, admin panel, OpenTelemetry trace viewer, PII and budget guardrails, persistent memory via Postgres or Redis, MCP tool governance, and OIDC authentication. That's a genuine time-saver — the vendor claims three weeks of effort saved, and that's plausible given the breadth of components. The self-hosted model is the key differentiator: no per-execution fees, your infrastructure, your code, your data. That's a direct answer to LangGraph Platform's per-node billing and lock-in. The GPL 3.0 license is a double-edged sword: it's open and auditable, but it may impose copyleft obligations if you modify and distribute the engine. The documentation and configuration are clearly developer-oriented; there's no point-and-click UI for non-engineers. Also, the commercial side is consulting-only — you won't find published SaaS pricing. If you need a fully managed platform, this isn't it. But for teams with Python expertise and a desire to control their stack, it's a pragmatic way to get production-grade agents with minimal spin-up. The multi-LLM support (Anthropic, OpenAI, Gemini, Mistral, Cohere, vLLM) and observability integrations (Langfuse, Phoenix, Arize) give you flexibility and avoid lock-in. Overall, a solid choice for CTOs and platform leads who value control and cost predictability over convenience.

Models Under the Hood
as of 2026-08-30
Limitations
- The open-source Engine is licensed under GPL 3.0, which may impose copyleft obligations on derivative works.
- Self-hosting requires managing your own infrastructure and dependencies such as Postgres or Redis for persistent memory.
- The documentation and configuration are developer-oriented, targeting CTOs and Principal Engineers.
- Paid services are offered as fixed-scope consulting engagements, with no pricing published on the site; the open-source platform is not commercialized.

Where the pricing makes sense
The company stage and team size where Idun Agent Platform's pricing actually pencils out — and where peers do it cheaper.
For self-hosting teams, Idun Engine is free (GPL 3.0), offering a cost advantage over LangGraph Platform's per-node billing. Consulting services start at €5,000 for an audit, with integration engagements up to €22,000 — cheaper than hiring a full-time engineer for a multi-month project.
Setup time & first value
How long it actually takes to get something useful out of Idun Agent Platform — broken out by persona, not the marketing-page minute.
For a developer familiar with LangGraph or ADK: install via pip, init a project, and run it locally in about 15 minutes. First production deployment with memory, guardrails, and OIDC may take a few hours. For non-Python experts, expect a day or more.
Switching to or from Idun Agent Platform
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From LangGraph Platform: Move your existing LangGraph graphs to Idun Engine by adding an agent.yaml and .env; no code changes needed for the graph itself.
- ↗To LangGraph Platform: You can reuse your graphs, but you'll lose the runtime's built-in UI, guardrails, and OIDC, and face per-node fees.

Featured Head-to-Head Comparisons
Idun Agent Platform vs Spider Cloud
Idun Agent Platform is for teams building custom agent infrastructure who want self-hosted control and no per-execution fees. Spider Cloud is for AI/ML engineers who need fast, cheap web data for RAG or LLM-powered agents. Choose Idun if you own the agent pipeline and want to deploy it in production; choose Spider if your bottleneck is getting web data into your agents.
Idun Agent Platform vs Presto Voice
Presto Voice and Idun Agent Platform serve entirely different needs. Presto is a specialized drive-thru voice AI for QSR chains, offering high automation rates and upselling (now adopted by Dairy Queen), but it's contact-priced and closed. Idun is an open-source runtime for developers to deploy LangGraph/ADK agents as FastAPI services, focusing on self-hosting and avoiding per-execution billing. Choose Presto if you run a multi-location drive-thru and want proven voice automation; choose Idun if you're a technical team building custom AI agents and need a production-grade, vendor-independent runtime.
Idun Agent Platform vs Temporal Ai
If you need a battle-hardened durable execution platform for mission-critical workflows and AI agents that must survive failures, choose Temporal – it's trusted by OpenAI and offers full workflow-as-code flexibility. If you already have LangGraph or ADK agents and want to quickly serve them as production FastAPI services with built-in guardrails and self-hosting, Idun is the leaner, more convenient choice. Your decision hinges on whether you need a general-purpose orchestration engine or a specialized agent-to-service runtime.
Popular in Agent Frameworks & Orchestration
Temporal AI
Durable execution platform keeping AI agents and workflows running through failures with automatic state capture and retries.
