How It Works: A Look Under the Hood
ManageN8N is built on a sophisticated, secure, and scalable architecture designed to give you seamless control over your n8n instances. Understanding how the components work together can help you appreciate the power and security of the platform.
The End-to-End Flow
From Your Click to Your Server
Action in the Admin Panel
You initiate an action in our Next.js-powered admin panel—for example, deploying a template, creating a backup, or restarting an instance.
Secure API Request
The frontend sends a secure, authenticated request to our backend API. Our system validates your identity and permissions to ensure you are authorized to perform the action.
Job Enqueue
The API enqueues a job in our robust job queueing system, powered by BullMQ and Redis. This ensures that tasks are processed reliably and in the correct order.
Worker Orchestration
A dedicated worker process picks up the job. The worker contains the logic to orchestrate the task, whether it is calling a cloud provider's API to provision a server or preparing a command for the agent.
Agent Command Polling
The lightweight ManageN8N agent, running securely on your server, polls a dedicated, secure endpoint on our API approximately every 30 seconds to check for new commands.
Secure Command Execution
The agent receives the encrypted command, executes it locally (e.g., running a script to deploy a workflow, performing a backup), and then reports the results back to our API.
Dashboard Update
The API receives the results from the agent, updates the state in our database, and the frontend automatically refreshes to show you the latest status, metrics, and logs.
This polling-based, agent-driven architecture is inherently secure. We never initiate connections to your server, and the agent only executes signed, validated commands from our API. This ensures that your infrastructure remains secure and under your control at all times.
Core Architectural Components
| Component | Technology | Role |
|---|---|---|
| Frontend | Next.js | Provides the intuitive user interface where you manage your instances, templates, and organization. |
| API & Worker | Express & BullMQ | Orchestrates all backend jobs, manages licensing, and handles the logic for deployments and server setup. |
| Agent | Node.js | A lightweight process on your server that executes commands, deploys workflows, and reports metrics. |
| Database | PostgreSQL | The persistent data store for all platform state, including instance configurations, user roles, and template data. |
| Cache & Queue | Redis | Powers our job queueing system and provides caching for high-performance data access. |
| Reverse Proxy | Caddy | Manages SSL termination and securely routes traffic to the appropriate frontend or backend service. |
This robust, decoupled architecture ensures that ManageN8N is scalable, reliable, and secure, providing you with an enterprise-grade foundation for your n8n automation infrastructure.
