Every business has processes that someone automates with a cron job and a Python script — until that person leaves and nobody knows how it works. n8n replaces those fragile scripts with visual, maintainable workflows that anyone on the team can understand.
What Is n8n?
n8n is an open-source workflow automation platform. Think Zapier, but self-hosted, with a fair-code license, and with the ability to write custom JavaScript/TypeScript when the visual builder isn't enough. It connects to 400+ services out of the box and supports webhooks, cron triggers, and manual execution.
Real Workflows We've Built
Here are actual automations running in production for our clients:
- Lead capture: Website form submission triggers a workflow that enriches the lead via Clearbit, creates a HubSpot contact, sends a Slack notification, and queues a personalized email sequence
- Content publishing: When a blog post status changes to "published" in Payload CMS, n8n generates social media posts via AI, schedules them across platforms, and updates the internal content calendar
- Invoice processing: Incoming invoices hit a webhook, get parsed by an AI node, matched against purchase orders in the ERP, and routed for approval — or auto-approved if under threshold
- Monitoring alerts: n8n polls health endpoints every 5 minutes, aggregates status across services, and sends tiered alerts (Slack for warnings, PagerDuty for critical)
Why Not Zapier or Make?
Three reasons: cost, control, and capability. Zapier charges per task execution, which gets expensive fast — a client's lead enrichment workflow alone would cost $300/month on Zapier. With n8n self-hosted, the cost is the server ($20/month) regardless of volume.
Control matters too. n8n runs on your infrastructure, so sensitive data never leaves your network. And when you hit a limitation in the visual builder, you can drop into a Code node and write arbitrary JavaScript — something Zapier fundamentally doesn't support.
The AI Integration Angle
n8n's AI nodes are where things get interesting. You can chain LLM calls with structured data transformations, build RAG pipelines with vector store nodes, and create AI agents that use tools — all within the visual workflow builder. We've built document processing pipelines that extract, classify, and route information using a combination of GPT-4o and traditional logic nodes.
Getting Started
Self-hosting n8n takes about 15 minutes with Docker. The learning curve is gentle — if you can draw a flowchart, you can build an n8n workflow. Start with a simple webhook-to-Slack notification, then layer on complexity as you identify more processes worth automating.
The best automation is the one that eliminates a task your team does manually every day. n8n makes building that automation fast enough that the ROI is measured in days, not months.
