Why Developers Are Choosing n8n (And What You Need to Know Before You Start)

Published May 31, 2025 | By Matt

If you’re a developer who’s ever duct-taped APIs together or built the same internal tool three times over, you’ve probably thought, “There has to be a better way.”

That’s where n8n comes in — a self-hosted, open-source workflow automation tool that’s flexible enough for coders and powerful enough to replace entire backend scripts.

In this guide, we’ll walk through:

  • What n8n is and why it’s catching on
  • A developer-focused FAQ
  • Real-world use cases
  • Side-by-side comparisons with Zapier and Make

What Is n8n? (In Developer Terms)

n8n is a Node.js-based automation platform that lets you visually design workflows but also drop in custom JavaScript, call APIs, and trigger logic based on real data. Think of it like:

  • Zapier (but open-source),
  • Airtable Automations (but powerful),
  • Serverless functions (but easier to maintain),
  • A no-code/low-code backend dev tool (with full-code options).

Developer FAQ: What Coders Actually Want to Know

Question Answer
Can I write code in n8n? Yes. Use Function or FunctionItem nodes to run JavaScript.
Is it open source? Yes. Under a Fair-code license
How do I call an API? Use the HTTP Request node — customize headers, auth, body, query strings, etc.
Does it support conditionals and loops? Yes — IF, Switch, SplitInBatches, and LoopItems nodes.
Can I self-host? Yes — run on Docker, Railway, Render, VPS, or local.
Can I store credentials safely? Yes — secure credential management and use of env variables.
Can I use it in CI/CD or with Git? Workflows can be exported/imported as JSON — version control possible.
What language is it built with? TypeScript (server) + Vue (UI). You’ll write JavaScript in custom logic.

Real-World Use Cases for Developers

Use Case Example Workflow
Internal Tools Scrape a competitor’s price → Write to Google Sheet → Send Slack alert
Marketing Automation New lead in Webflow → Enrich with Clearbit API → Add to Mailchimp
AI Agents Blog idea → Call GPT-4 → Format in Markdown → Publish to WordPress
Ops Monitoring Watch server logs → Regex match error → Send Telegram message
Database Sync Postgres → Sanitize → Send to Supabase
Webhook Router Stripe, Typeform, Calendly, etc. → Unified webhook → Route with logic

How n8n Fits Into a Developer Stack

Picture this:

You’ve got GitHub, Stripe, Postgres, and Slack. You want a way to monitor events, respond to errors, and automate tasks — without spinning up Lambdas or writing an Express app.

With n8n:

  • You drop in a Webhook Trigger for GitHub.
  • Add logic in a Function node.
  • Store data in Postgres.
  • Send alerts via Slack.
  • Log everything — and reuse the flow in your next project.

You get the control of code with the speed of visual logic.

🧩 Stop Rebuilding the Same Internal Tools

If you’ve ever duct-taped APIs, spun up throwaway Express apps, or hit the limits of Zapier, there’s a better way.

  • 🛠️ Self-hosted, open-source, and built for coders
  • ⚙️ Write custom logic in JavaScript, trigger with webhooks, and version in Git
  • 🤖 Build real AI agents that can reason, act, and automate — fast

Developers around the world are replacing brittle glue code with durable, visual logic. You should too.

Should You Use n8n as a Developer?

Yes, if you:

  • Want to automate things your way without vendor lock-in
  • Love APIs, hate repetitive glue code
  • Need to combine scheduled jobs, webhooks, custom logic, and integrations
  • Want to build AI agents or automations that respond in real time

No, if you:

  • Only want drag-and-drop “Zaps” with no technical complexity
  • Can’t self-host or don’t want to manage infrastructure
