Ditching Zapier for n8n: How I Built a $0 Self-Hosted AI Automation Engine on Docker (Save $720/Year)

说明与用途

作者用 Docker 部署自托管 n8n 替代 Zapier，90 天内处理 142,680 次任务，节省 1,242 美元，Webhook 延迟降至 12–35 毫秒。

问题

Commercial workflow automation platforms lock users into expensive per-task pricing, limited features, and data privacy risks.

结果

The self-hosted n8n setup handled 142,680 executions in 90 days, saved $1,242/year compared to Zapier, achieved 60x faster webhook latency, and enabled local AI integration without vendor lock‑in.

工作流

• Set up project directories and permissions
• Generate cryptographic secrets in .env
• Create docker-compose.yml with services for n8n, PostgreSQL, and Caddy
• Deploy containers with Docker Compose
• Verify HTTPS and webhook functionality
• Monitor task execution and performance

证据

Over 90 days, the engine processed 142,680 execution tasks across 18 autonomous workflows
