In today’s digital world, automation is no longer a luxury — it’s a necessity. Whether you’re managing a startup, running a freelance business, or building a SaaS product, automating repetitive tasks can save hours of manual work each week. One of the most powerful open-source automation tools available right now is n8n.
In this complete tutorial, we’ll dive deep into how n8n (pronounced "n-eight-n") can revolutionize your workflow, help you connect your favorite tools, and create powerful automations — all with little to no code.
