This mind-blowing open-source tool is saving developers boatloads of hours every week -- which is why so many people have been talking about it lately.
This is state-of-the-art automation - effortlessly connect several different tools, APIs and even AI models into one powerful workflow.
It's like Zapier or Make but far better -- far far more flexibility and control -- they actually built this with coders in mind.
It’s open, powerful, and gives you the option to self-host it on your own server if you want to keep everything private.
How it all works
n8n is built around a simple concept: workflows made of nodes.
Each workflow starts with a trigger (for example, a new form submission, an incoming webhook, or a scheduled event).
From there you chain together nodes — each representing an action, such as calling an API, transforming data, sending an email, or running custom JavaScript.
Here’s what a typical n8n workflow might look like:
When a new order comes in via your website →
Fetch customer data from your database →
Ask an AI model to generate a summary →
Post that summary into Slack.
Everything flows visually, step by step, so you can see exactly how data moves through the process.
Hundreds of integrations and counting
n8n already connects to 500+ popular apps — from Google Sheets and Notion to GitHub, Slack, Airtable, and more.
And even if there’s no official integration, you can always use the HTTP Request or Database nodes to connect to almost any API or data source.
This flexibility means you can automate things across your entire stack — not just between mainstream SaaS tools.
The AI effect
Unlike traditional automation platforms n8n is built to work seamlessly with AI.
You can drop in nodes for OpenAI, Anthropic, Hugging Face, or custom LLM APIs to create “AI agents” that think and act inside your workflows.

The Gold standard for AI news
AI will eliminate 300 million jobs in the next 5 years.
Yours doesn't have to be one of them.
