Frequently asked questions
What is an n8n automation agency?
An agency that designs and builds automated workflows on n8n — an open-source workflow automation tool. BuildFastLabs adds AI/LLM steps and custom integrations so your business automates work that generic tools cannot.
Can you self-host n8n for us?
Yes. We can set up self-hosted n8n on your infrastructure or use n8n cloud, configure it securely, and hand over full ownership and documentation.
Which AI models do you use inside n8n?
We are model-agnostic — Claude, GPT, and open-source LLMs via OpenRouter — chosen per workflow based on accuracy, cost, and privacy.
