Alternatives / n8n

Open-source alternatives to n8n

5 genuinely open-source alternatives with 119.8K combined GitHub stars. The most starred is Flowise AI, with 53.3K stars.

Why look for a n8n alternative?

n8n's fair-code license caps self-hosted use once you scale past a single instance or resell it, and its cloud plans charge per workflow execution — a cost that climbs fast for teams running many automations. People look for alternatives when they need a fully permissive open-source license, a different execution model, or to avoid per-execution pricing entirely.

#1

Flowise AI

Visual drag-and-drop builder for AI agents and LLM pipelines.

Apache-2.0 alternative to Langflow with chatflow and agentflow paradigms, embeddable chatbot widgets, and API endpoints — closer to an AI pipeline builder than a general Zapier-style tool.

  • Purpose-built for AI agent and LLM pipelines
