The verdict
The deciding question is how your automations bill. Zapier charges per task, where every action step counts, so a 10-step Zap running 1,000 times bills 10,000 tasks. n8n charges per execution, where that same flow bills 1,000 runs regardless of step count, and the self-hosted Community Edition bills nothing at all. At any real volume that gap compounds into the difference between a 30 USD bill and a four-figure one.
So: pick Zapier when speed-to-live and integration breadth (7,000+ apps) matter more than the monthly cost, and your flows are simple and infrequent. Pick n8n when your flows are multi-step, run often, or need code-level control, and you'll accept a little setup to halve or quarter the bill. For most lean B2B founders who plan to lean on automation hard, n8n is the better long-term home, with Zapier as the no-friction starting point.
