How it works
n8n is a visual workflow builder where each node represents an action (HTTP request, transformation, LLM call, database query). Workflows trigger on schedules, webhooks, or events. Self-hostable on a $20/month VPS with no per-execution fees.
Example
A marketing agency runs n8n workflows for: monitoring competitor websites for changes, drafting weekly client reports from GA4 + Meta Ads, posting to LinkedIn from a content queue, and enriching inbound leads with Clearbit data.
