What is n8n? Open-Source Workflow Automation Explained

Introduction

What is n8n? It is an open-source workflow automation tool that helps businesses and individuals connect apps, APIs, and databases into seamless automated processes. It eliminates repetitive tasks, minimizes human error, and enables teams to save time while focusing on more meaningful work.

Unlike traditional automation tools with fixed pricing or limited integrations, n8n offers a different approach. It can be self-hosted, providing organizations with full control over their data and workflows. For companies that prioritize privacy, customization, and scalability, this makes n8n an appealing option.

What is n8n?

n8n (pronounced “n-eight-n”) is an automation platform designed to connect apps, databases, and APIs into seamless workflows. It uses a node-based system where each node represents a task or integration. By linking these nodes, users can create workflows that automate anything from simple notifications to complex multi-step business processes.

Launched in 2019, n8n quickly gained popularity among developers and businesses seeking alternatives to costly proprietary automation tools. Today, it is widely adopted across various industries for its flexibility and the independence it offers. Unlike most competitors, n8n can be self-hosted on your own infrastructure — such as a VPS — so you’re not limited to a single vendor or pricing scheme.

Because n8n is open-source, anyone can contribute, review the code, or even build custom nodes. You can explore its active development and community contributions on the official n8n GitHub repository.

How n8n Works

At its core, n8n connects actions and triggers. A trigger could be a new email, a customer order, or an API call. When the trigger activates, a sequence of actions starts, represented by nodes. Each node performs a task, such as adding a database entry, sending a Slack message, or transforming data before passing it to the next step.

The visual editor makes building workflows simple. Users drag and drop nodes onto a canvas and connect them. This method is intuitive for non-technical users but also versatile enough for developers. For those who want more control, n8n allows adding custom code directly within workflows.

Key Features of n8n

n8n combines simplicity with power. It provides over 350 ready-to-use integrations covering CRMs, cloud storage, social media platforms, and databases. This variety makes it easy to create workflows that match real-world business needs.

Its fair-code license is another notable feature. While n8n is open-source, the license prevents its core from being resold. This model encourages sustainability while allowing users to customize the platform.

Reliability is also built in. With error handling and retry logic, workflows can recover from temporary service failures without breaking. By adding webhook support, JavaScript execution inside nodes, and strong scalability, you get a tool that appeals to both individuals and enterprises.

Why Businesses Choose n8n

Many businesses face a trade-off. Tools like Zapier are easy to set up but become costly as they scale. Building custom automations internally offers control but demands significant developer time.

n8n bridges this gap. By self-hosting, businesses can run unlimited workflows without paying per-task fees. They also retain full control of their data, which is essential in regulated industries under laws like GDPR or HIPAA.

For startups, n8n offers an affordable entry point. For enterprises, it provides the flexibility to integrate deeply with existing infrastructure.

Common Use Cases of n8n

Automation with n8n takes many forms. Marketing teams use it to sync data from forms into CRMs and email tools. E-commerce businesses depend on it to automatically update inventory and notify customers about orders. Data teams process information from APIs and send it to databases for reporting. DevOps engineers monitor servers and trigger alerts for downtime. Finance teams generate daily reports by pulling data from payment systems and formatting it automatically.

These examples demonstrate n8n’s versatility across various industries.

Real-World Use Cases of n8n

The impact of n8n becomes more evident through detailed scenarios.

A marketing agency managing campaigns on Google Ads, Facebook, and LinkedIn saves hours by automating reporting. Instead of manually collecting data, n8n retrieves metrics from each platform, consolidates them, and provides a dashboard update every morning.

An e-commerce business uses n8n to manage Shopify orders. When a new order comes in, stock levels update automatically, invoices are generated instantly, and customers receive a shipping confirmation email — all without human input.

In IT and DevOps, uptime is essential. If a server fails, n8n can log an issue in Jira, alert engineers in Slack, and initiate responses like restarting a service or scaling resources.

Finance teams also benefit. Daily Stripe or PayPal transactions automatically flow into accounting software. Reports generate themselves and arrive in executives’ inboxes before the workday begins.

These real-world workflows demonstrate how n8n adapts across marketing, retail, IT, and finance.

How Much Does n8n Cost?

The cost of n8n depends on deployment. Self-hosting is free; the only expense is your infrastructure, like a Zynoo VPS. For high workflow volumes, this option is the most cost-effective.

For those who prefer less setup, n8n Cloud is available. Pricing begins at about $20 per month and increases with usage. Higher tiers cater to professional and enterprise needs, though they include limits and recurring fees.

Large organizations can also access enterprise plans, which include dedicated support and service-level agreements. However, for most small and medium businesses, self-hosting n8n on a VPS offers the best balance between cost and control.

Hosting n8n on a VPS

Running n8n on a VPS is simple. A typical setup includes installing Docker, deploying n8n with Docker Compose, and adding SSL certificates for security. Once installed, you can access the n8n editor in your browser and start creating workflows.

With VPS hosting, you retain ownership of your infrastructure. You manage data storage, resource allocation, and scaling. For businesses dealing with sensitive data, this level of control is critical. Zynoo VPS plans make it simple to start small and expand resources as automation needs increase.

Future Trends in Automation

Automation is advancing, and n8n is ready to grow with it. AI-powered automation is among the most exciting innovations. By integrating with platforms like OpenAI, workflows can go beyond basic tasks to include advanced features like natural language processing and predictive analytics.

Another trend is hyper-automation, where companies seek to automate not just single tasks but complete end-to-end processes across departments.

The growth of low-code and no-code tools will continue. n8n already supports non-technical users with its visual editor, and future improvements will make it even easier to create complex workflows without coding.

Finally, data privacy regulations like GDPR will bolster the case for self-hosted solutions. Companies will increasingly favor platforms like n8n that enable them to process sensitive data securely on their own infrastructure.

Conclusion

n8n is more than just another automation platform. It is a flexible, open-source solution that enables businesses to automate workflows on their own terms. With its visual editor, extensive integrations, and self-hosting option, n8n provides accessibility, scalability, and control all in one package.

At Zynoo, we suggest hosting n8n on a VPS. This method allows businesses to automate freely, maintain control over sensitive data, and scale easily as their needs expand.

As automation becomes essential to modern business, n8n provides a future-proof solution that adapts to both simple and complex workflows — making it a smart choice for teams of all sizes.
