FAQ · 2026

Frequently Asked Questions

What specs do I need for Hermes Agent, OpenClaw, or n8n?

For an isolated AI agent or automation instance running headless browser automation and persistent memory, we recommend 4–8 GB RAM and 2–4 vCPU threads. On Hostingsurge, our engineering team builds and hardens your private instance on-demand within 24–48 hours.

How is Hostingsurge different from an unmanaged VPS?

With an unmanaged VPS you handle Linux kernel patching, Docker networking, TLS certificates, and backups yourself. Hostingsurge delivers managed EU container isolation, automatic HTTPS, and on-demand AI agent provisioning.
