n8n
Open-source workflow automation platform (alternative to Zapier and Make), which can be self-hosted for free. Connects apps + AI in visual flows.
What is n8n
n8n is an automation tool similar to Zapier or Make, but open-source and self-hostable. You build visual (drag-and-drop) workflows that connect 400+ apps (Gmail, Slack, Sheets, CRMs, databases, AI providers) and execute automatic actions when something happens (new email, lead on site, 9 AM trigger, etc).
Why n8n vs Zapier/Make
- Cost: self-hosted = free (you pay only the server, ~$5-20/month on Hetzner). Zapier/Make: $50-500/month at high volumes.
- Privacy: your data stays on your server. Important for GDPR / sensitive data.
- Flexibility: you can write JavaScript code in custom nodes. Much more powerful than pure low-code.
- AI native: nodes for OpenAI, Anthropic, Pinecone, embedding, RAG - native integration.
Typical use cases
- New lead on site → AI writes personalized email → auto send + CRM add
- New Gmail email → AI classification (urgent/spam/normal) → response or forward
- Shopify order → Slack notification + auto invoice + confirmation email
- Missed Vapi call → automatic apology SMS + proposed reschedule
- Daily digest: scrape competitors, AI summarize, 9 AM email
How to set up
For self-hosted: Hetzner server with Coolify (10 min setup) → install n8n container → connect domain. Total cost: $5-15/month. For cloud n8n: $20/month starter, $50 pro. At DevoneX we recommend self-hosted for control + GDPR.
