Introducing n8n: A Free Open-Source Automation Tool

Automation tools are not new, with many already using IFTTT or the Shortcuts app on iPhones to handle repetitive tasks. However, these tools are often complex or lack support for advanced workflows. n8n addresses these issues by allowing seamless connection of apps like email, CRM, social media, and databases. It is a no-code platform with the option for custom code, free, open-source, and can be self-hosted on an old laptop.

n8n is a free, open-source workflow automation tool that can be run on a personal server. It acts as a digital assistant for apps, connecting different services to manage repetitive tasks. n8n allows the creation of custom automated workflows by visually linking apps and actions, moving data without heavy coding. It is similar to Zapier or Power Automate but offers self-hosting for full control.

n8n uses an event-driven, low-code approach. Users build workflows in a visual editor by dragging and dropping 'nodes,' each representing an action or trigger, such as receiving an email or posting a message in Slack. Connecting these nodes allows n8n to execute actions step-by-step when a trigger event occurs, all configured through an intuitive interface without scripting.

Docker is one of the easiest ways to run n8n on a PC, containing everything in a lightweight environment to avoid dependency issues common with local installations. After installing Docker, open the terminal and launch n8n in a container. This command maps n8n to port 5678 on a laptop, allowing browser access.

Using n8n's editor is straightforward. Once running, open the workflow editor in a browser to create a new workflow and add nodes. Typically, start with a trigger node, such as 'new email received' or a schedule timer, then add action nodes. Each action node may read data, send emails, update spreadsheets, or call APIs. Connect nodes to define data flow.
