n8n alternative for AI agents
n8n is a superb open-source workflow automation tool — hundreds of integrations, a visual canvas, self-hostable, and it has added solid AI and agent nodes. But n8n orchestrates steps you define; a2a hosts an agent that decides. This is workflow automation vs agent infrastructure — and the two can even work together.
Where n8n is genuinely strong — and where a2a cloud is different.
Visual workflow automation, done exceptionally well
n8n is genuinely excellent at what it's built for: connecting hundreds of services on a visual node canvas, running deterministic multi-step flows, and letting you self-host the whole thing. Its AI and agent nodes make it a powerful way to wire LLM calls into an automation. If your problem is 'when X happens, do these steps in this order,' n8n is a joy to work in — and many teams rightly love it.
Deploy an autonomous agent as a governed service
a2a cloud isn't a workflow builder. You deploy real agent code — any framework — and a2a hosts it as a Knative or Kubernetes container service with managed Postgres, MCP and API surfaces, and scoped grants. Agent API, public `/invoke`, and standard MCP `tools/call` executions receive signed receipts; explicit `ctx.sandbox` code uses a separate microsandbox. n8n orchestrates the steps you draw; a2a hosts an agent that decides its own.
a2a cloud vs n8n, dimension by dimension.
A fair comparison. Both columns are accurate as we understand the products today — the difference is what the runtime owns by default.
Pick the tool that matches the job.
Reach for n8n when
- Your problem is a deterministic, node-based flow across many SaaS integrations.
- You want a visual canvas and low/no-code authoring, and prefer to self-host.
- You're wiring LLM calls into an existing automation rather than shipping a standalone agent.
Reach for a2a cloud when
- You're deploying an autonomous agent that decides its own steps — not a fixed workflow.
- You want the agent's own runtime, managed Postgres, MCP server, frontend, and API in one deploy.
- Use both: keep your n8n workflows and have them call an a2a agent's API or MCP server as a step.
Trust the receipt.
a2a cloud deploys any agent — LangGraph, OpenAI Agents SDK, CrewAI, or custom — and ships it with a managed Postgres database, an MCP server, an API, a frontend, and an Ed25519-signed receipts on governed execution paths. Scoped grants, no ambient production access. One deploy, the whole agent app, with proof.
