n8n and Runtime at a glance

n8n is a source-available workflow automation platform popular with technical teams. You build workflows on a node canvas, add AI agent nodes and custom code, and can self-host it for full control over data.

Runtime is the AI agent harness for payment teams. From payment ops to risk, compliance, and support, anyone on the team can build agents that work their queues on their own computers inside your cloud, called from Slack, Teams, email, SMS, or voice, with approvals and a full audit trail.

n8n is for engineers who want to build automations themselves. Runtime is for payment and risk teams that need agents running on sensitive data with the controls already in place.

How they differ

Who builds, and who maintains

In n8n, a technical user wires nodes on a canvas and maintains the workflow as the process changes. In Runtime, the ops analyst who owns the SOP describes the work in plain English, and the agent handles the steps and the exceptions. Engineering sets the guardrails instead of building every workflow.

Agents on exceptions, code for solved processes

Runtime agents reason through the cases a fixed workflow can't: a return with an unfamiliar code, a payout held by the processor, a recon break with three possible causes. Once a case type is solved, the agent writes it as a deterministic script that runs as a template. The script lives in your repos, so engineers own it when it becomes mission-critical.

The controls you'd otherwise build

Both can run in your environment. The difference is what comes with it. Runtime ships approvals before money moves, masked credentials, card numbers and SSNs stripped from prompts and logs, RBAC, evals, and model routing with fallbacks. With n8n, approvals, examiner-ready audit, and evals are yours to build.

An engineer who knows payments

Runtime pairs you with a forward-deployed AI engineer who has built payment and fintech infrastructure. They map your processes, build the first agents with your team, set up guardrails, and train your admins.

Where n8n is stronger

Developer control. A node canvas plus code nodes gives engineers fine-grained control over every step.
Source-available and self-hostable. You can inspect it and run it yourself.
General-purpose. Works for any department and any kind of automation, not only finance and payments.
Mix of AI and code. AI agent nodes and custom code sit side by side in one workflow.

Which should you choose

Choose n8n if

Your engineers want to build and maintain workflows themselves
You want a self-hosted automation tool at low cost
Workflows mix APIs, code, and AI steps
You have time to build approvals and audit on top

Choose Runtime if

Ops, risk, and finance teams should build agents from their own SOPs
The work is mostly exceptions that need judgment
You need approvals on money movement and an audit trail on day one
You want solved processes written as code in your repos

Frequently asked questions

Is n8n good for fintech?

n8n is a capable, self-hostable workflow tool, and technical teams use it for many kinds of automation. For payment operations you would build approvals, PII masking, audit exports, and evals on top yourself. Runtime includes those for payment, risk, and finance teams.

Can n8n and Runtime both run in my own cloud?

Yes. n8n can be self-hosted. Runtime runs agent computers in your AWS, GCP, or Azure account, or fully self-hosted via Helm, and lets you serve open-weight models in your cloud for PCI and PII work.

What is the best n8n alternative for payment operations teams?

If your engineers want to build and maintain workflows themselves, n8n is a good fit. If ops, risk, and finance teams need to build agents from their SOPs, with approvals before money moves and a record a sponsor bank will accept, Runtime is built for that.

Do I need engineers to use Runtime?

No. Ops teams build agents from their SOPs in plain English, and engineering keeps control of access, credentials, and the code agents write. A forward-deployed engineer helps build the first agents with your team.
