Google Agent Development Kit (ADK) vs n8n

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Google Agent Development Kit (ADK) Agents	n8n Agents
Tagline	Google's open-source framework for building, evaluating, and deploying production AI agents	Source-available workflow automation with first-class AI-agent and RAG building blocks.
Category	Agents	Agents
Pricing	Free· Framework itself is free and open-source (Apache 2.0). Costs come from the underlying model provider (e.g. Gemini API / Vertex AI usage) and any hosting infrastructure (Cloud Run, GKE, Agent Engine).	Freemium· Starter: 20€/mo, billed annually · Pro: 50€/mo, billed annually · Business: 667€/mo, billed annually · Enterprise: Contact Sales
Model	Gemini (default) plus Claude, GPT-4/5, Llama, and other providers via LiteLLM	Multi-model

Pros	Genuinely open-source (Apache 2.0) with active Google engineering behind it, not a hosted-only product Multi-language: first-class Python, Java, and Go SDKs — rare among agent frameworks that are usually Python-only Built-in dev UI (`adk web`) with trace inspection, event stream, and session replay speeds up debugging enormously Model-agnostic via LiteLLM — Gemini is default but Claude, GPT, and local models plug in cleanly Rich multi-agent primitives out of the box: SequentialAgent, ParallelAgent, LoopAgent, and hierarchical sub-agents Tight Google Cloud integration for deployment (Cloud Run, GKE, Agent Engine) plus native BigQuery/Vertex Search tools Evaluation harness with trajectory-level scoring is included, not a separate paid add-on First-class MCP (Model Context Protocol) client and server support	500+ integrations plus arbitrary JS/Python escape hatches Self-hostable via Docker with full feature parity Native nodes for LLMs, vector DBs, RAG, and MCP Massive community (~194k GitHub stars) and node ecosystem Built-in cron, queues, retries, credentials, and audit logs
Cons	Documentation and examples lean heavily on Gemini + Google Cloud; non-Google paths work but feel like second-class citizens API surface is still evolving — breaking changes between minor versions have been common through 2025-2026 Multi-agent orchestration primitives are powerful but the graph/callback model has a real learning curve compared to a plain prompt loop Agent Engine deployment is convenient but locks you into GCP billing and quotas TypeScript/Kotlin support lags the Python SDK in features and community examples	Fair-Code license is not OSI-approved open source Agent debugging gets messy on large multi-branch canvases Cloud pricing scales by executions, can surprise heavy users Steeper learning curve than Zapier for non-engineers
