Modulo vs n8n: what's the difference?

n8n is a popular open-source workflow automation tool. It connects APIs, sequences tasks, and automates business processes through a visual editor. It is excellent for what it does: connecting services and automating repetitive tasks.

Modulo is a self-hosted platform for governing agent-powered software delivery. It focuses on the specific domain of SDLC governance: validating agent outputs, managing human review, maintaining audit trails, and progressively granting autonomy.

What n8n does well

n8n excels at connecting services through its large library of integrations. If you need to automate a business process that spans multiple SaaS tools - create a ticket in Jira when a form is submitted, send a Slack notification when a deploy completes - n8n is a strong choice. Its visual editor makes it accessible to non-developers.

What n8n does not do

n8n has no concept of agent governance. It does not validate agent outputs against schemas, run deterministic gates, manage human-in-the-loop review, maintain an immutable audit trail, or track progressive autonomy. These are outside n8n's design scope. n8n is a workflow automation tool, while Modulo is an agent governance platform.

How they relate

n8n and Modulo serve different purposes and can complement each other. A team might use n8n for general business process automation (connecting CRM, support tickets, marketing tools) and Modulo for SDLC governance (validating agent outputs, managing code review, maintaining audit trails).

The difference is domain specificity. n8n is horizontal - it connects anything to anything. Modulo is vertical - it governs agent activity within the software delivery lifecycle specifically.

The principle behind this: deterministic gates catch failures before they reach a human reviewer, and audit as a first-class output means the history you inspect is exactly what happened.
