What is n8n?
n8n is an open source workflow automation platform, built for those wanting more control and flexibility than tools like Zapier: it can be self-hosted for free on your own server, and in recent years has added AI nodes that let you plug language models directly into automation flows.
Its typical audience is more technical than Zapier or Make's: n8n offers a visual node-based editor but also allows writing custom JavaScript code when the required logic goes beyond what a drag-and-drop interface can express.
Main Features
- Visual node editor: builds automation flows by connecting blocks without writing everything from scratch
- Built-in AI nodes: plugs language models (OpenAI, Claude, local models) directly into workflows
- Free self-hosting: installs on your own server with no license cost for the community version
- Custom code: allows writing JavaScript for logic not covered by predefined nodes
- Hundreds of integrations: connects to common external services (CRM, email, database, API)
- Triggers and webhooks: starts flows based on external events or custom HTTP requests
How Does n8n Work?
You build a flow by dragging nodes onto a visual canvas: a trigger node starts the workflow (e.g. a new email arriving), followed by processing nodes (e.g. an AI model analyzing its content) and final action nodes (e.g. creating a task in another tool).
For self-hosters, n8n runs on your own server (even a small VPS), eliminating recurring cloud subscription costs, provided you handle server maintenance and security yourself.
Who is n8n for?
- Developers and technical teams wanting more control than Zapier
- Companies wanting to avoid growing cloud automation subscription costs
- Those needing to integrate custom AI models into their workflows
- Teams with data privacy requirements preferring self-hosted infrastructure
- Those already experienced with no-code tools who need more complex logic
Use Cases
- Automating incoming email classification with a connected AI model
- Building data pipelines connecting multiple different services and databases
- Creating custom chatbots by connecting a language model to external channels
- Automating internal business processes without relying on costly cloud subscriptions
- Integrating legacy systems with modern services via custom webhooks
Pricing
The n8n community version is free for self-hosting. There's also a paid managed cloud version, starting around $20/month, for those preferring not to handle server maintenance.
Pros and Cons
Pros:
- Free self-hosting eliminates recurring costs for high automation volumes
- More flexible than Zapier thanks to the ability to write custom code
- Built-in AI nodes enable native smart automations
Cons:
- Requires technical skills for self-hosting and server maintenance
- Steeper learning curve than pure no-code tools like Zapier
- The managed cloud version still has a monthly cost to consider
Final Verdict
n8n is the best choice for technical teams wanting advanced automation without Zapier's recurring costs, especially if already comfortable with self-hosting. For those seeking immediate simplicity without technical skills, Zapier or Make remain more accessible.
