Frequently Asked Questions
Should I choose n8n or Activepieces for workflow automation in 2026?
Choose n8n (`n8n-io/n8n`, 208.2k stars, Fair-Code) when you need an extensive catalog of 400+ battle-tested enterprise SaaS nodes, complex visual data transformation with JavaScript/Python, and native LangChain AI agent building. Choose Activepieces (`activepieces/activepieces`, 25.1k stars, MIT) when your organization requires a 100% permissive MIT license with zero commercial restrictions, modular TypeScript pieces, and native Model Context Protocol (MCP) server support.
How do n8n and Activepieces cut Zapier and Make bills by 91%?
Commercial integration platforms charge punishing task-based pricing tiers - Zapier charges $299-$1,500+/month once executing 50k-100k tasks, while Make charges steep operation and concurrency markups. Self-hosting n8n or Activepieces on a single $40-$85/month cloud VPS executes hundreds of thousands of webhook triggers, data syncs, and multi-step workflows with zero per-step execution penalties (-91.5% savings).
