n8n vs Zapier

n8n and Zapier both offer workflow automation but cater to different audiences. n8n provides a visual builder with deep code-level control: you can insert JavaScript or Python nodes anywhere, self-host with Docker (full source code access), and integrate native AI models directly into workflows with RAG support. It also offers unique features like re-running single workflow steps, replay/mock data for testing, and a traceable AI agent canvas. In contrast, Zapier prioritizes no-code ease with 9,000+ app integrations, Tables for data storage, Forms for triggers, and Canvas for AI-assisted workflow planning. Zapier's AI capabilities include Copilot, Agents, MCP, and chatbots, but they are cloud-only. For integrations, Zapier's catalog is massive (9,000+ vs 500+), but n8n allows custom API connections flexibly. n8n also supports human-in-the-loop approvals and git-based version control, features missing in Zapier. For testing, n8n's step-level replay and mock data are more developer-friendly than Zapier's live testing. Overall, n8n excels in customizability and security, while Zapier excels in simplicity and app ecosystem breadth.

n8n follows a freemium model: the self-hosted version is free forever with no execution limits (only a per-user license fee for enterprise features). The cloud version has a free tier with 2,000 monthly executions and 2 active workflows, then paid plans start at $20/month for 25k executions and 5 workflows. Self-hosting can be cost-effective for high volumes. Zapier also has a free tier with 100 tasks/month and 5 active Zaps, with paid plans starting at $19.99/month for 750 tasks. Zapier's pricing scales per task, which can become expensive for high-volume automation. Both tools have enterprise plans with custom pricing. n8n's self-hosted option gives unlimited executions at no additional cost, making it far cheaper for high usage. For teams with few workflows but high task counts, n8n self-hosted is the best value. For low-task, simple needs, Zapier's free tier is sufficient, but paid plans quickly add up.
