RunOnVPS

RunOnVPS is a free directory and calculator that checks the minimum VPS requirements for 50+ self-hosted apps (Nextcloud, Immich, Jellyfin, n8n, Vaultwarden and more). Every app page lists minimum and recommended RAM, CPU and disk from official sources, Docker Compose quick-start where available, side-by-side comparisons, and a stack calculator that totals the server size you need. No sign-up required.
