Why does Dify crash on 2GB or 4GB VPS plans on StackPilot?

Weaviate vector indexing plus Python Celery workers and Next.js frontend consume ~5.5GB RAM at idle. Giving Dify 16GB RAM (Hostinger KVM 4) prevents OOM kills completely.

Can I pair self-hosted Dify with self-hosted n8n on the same server on StackPilot?

Absolutely! On a 16GB KVM 4 or 32GB UltaHost VDS, n8n handles deterministic webhooks while Dify handles agentic RAG reasoning over internal Docker DNS.

Can I test Dify on cloud hardware before committing long-term on StackPilot?

Yes — use our /go/vultr-promo link to claim $300 in 30-day Vultr cloud credit and benchmark your exact RAG workload first.
