n8n

n8n is open-source / fair-code workflow automation built for technical teams. You get a visual builder, plus JavaScript or Python when a node needs real code. Run it yourself or use n8n cloud. The main repo (n8n-io/n8n) has 200k+ GitHub stars.

What People Use It For

This is the heart of it for me. n8n is less "another Zap" and more a place to wire real business flows end to end:

Connect apps and move data between CRM, Slack, Stripe, HubSpot, sheets, and the rest of the stack
Lead capture, enrichment, scoring, and routing so inbound does not die in a form inbox
Support triage and notifications when tickets, alerts, or customer signals need the right person fast
Onboarding, ops, and finance automation for the repetitive handoffs between tools
IT and security alerts that fan out, enrich context, and escalate with rules
AI agent workflows and RAG pipelines where LLM nodes are a step in the flow, not the whole product

Why Teams Pick It Over Zapier or Make

Self-host and data control when you care where workflows and credentials live
Code when you need it instead of fighting the last mile of a no-code UI
Branching and error handling for real graphs, not only linear zaps

Zapier and Make are still great for simple glue. n8n tends to win when the flow gets messy, sensitive, or code-shaped.
