# The 2026 AI automation tech stack: what professionals actually use

The market has settled: n8n, Make, GoHighLevel, Claude, fast small models, Retell/Vapi, and Hungarian integrations for Billingo, Számlázz.hu and MiniCRM. Why each one, and when.

## Key takeaways

- n8n is the professional workflow engine: open source, self-hosted, 100% GDPR-safe, no per-operation cost avalanche like Zapier, with built-in AI agent modules.
- Two model classes: a top model (Claude) for reading email, extracting structured JSON and writing natural prose; a fast cheap model for classification and filtering.
- Hungarian systems (Billingo, Számlázz.hu, MiniCRM) connect directly to n8n or Make over REST.

## Per-category stacks

Each category page in our workflow library ends with the report's recommended stack for that area: telephony, STT/TTS, e-signature, OCR, banking APIs, BI, short-video tools and more. Email, voice, SMS, chat, sales, quoting, contracts, invoices, scheduling, data, social, speech/OCR and process automation each have their own table.

## FAQ

**n8n or Make for a small business?**

Make to prototype fast without a server; n8n once volume grows or data must stay on your own EU server. Many projects start on Make and move to n8n.
