Not sure what specs you need? Here's a detailed breakdown based on real-world testing across our 33 reviewed providers.
Web Hosting (WordPress, Static Sites, CMS)
WordPress with 1-3 plugins and a caching layer (Redis or WP Super Cache) runs comfortably on 1 vCPU / 1GB RAM for up to 25K monthly visitors. Add WooCommerce or 10+ plugins and you'll want 2GB minimum. Multiple WordPress sites on a single VPS? Budget 512MB per additional site. NVMe storage matters here — database queries are 3-5x faster on NVMe vs SATA SSD. Best picks: Hetzner ($4.59/mo), Hostinger ($6.49/mo), see full WordPress VPS guide.
Game Servers (Minecraft, Valheim, ARK, Rust)
Game servers are RAM-hungry and latency-sensitive. Minecraft vanilla needs 2GB minimum; modded packs (FTB, ATM) need 4-8GB. Valheim needs 4GB for 10 players. The key metric is single-thread CPU performance and network latency to your players. Choose a datacenter closest to your player base. Best picks: Hostinger (4GB at $6.49/mo), Contabo (8GB at $6.99/mo), see full game server guide.
Development & CI/CD
Dev environments need flexibility more than raw power. A 2 vCPU / 2GB VPS handles most development workflows. For CI/CD runners (GitHub Actions self-hosted, GitLab Runner), budget 2 vCPU / 4GB per concurrent build. Docker Compose stacks with 3-5 services fit in 4GB. Hourly billing is essential — spin up test servers and destroy them when done. Best picks: Vultr ($5/mo, API-first), DigitalOcean ($6/mo, best docs), see full dev VPS guide.
E-commerce & Business Applications
E-commerce requires reliable I/O for database queries during checkout. Minimum 2 vCPU / 4GB for WooCommerce or Magento. Shopify headless setups can run on 2GB. Factor in SSL termination overhead and database connections — each concurrent user holds a connection. Managed VPS (Cloudways, ScalaHosting) eliminates the ops burden. Best picks: Kamatera (custom configs), Cloudways (managed), see full e-commerce guide.
VPN & Privacy
VPN servers are lightweight on CPU and RAM — 1 vCPU / 512MB handles WireGuard or OpenVPN for personal use. The critical factor is bandwidth: most budget VPS providers cap at 1-3TB/mo. BuyVM offers unmetered bandwidth at $2/mo. For commercial VPN services, you need multiple IPs and US datacenter diversity. Best picks: BuyVM ($2/mo, unmetered), Vultr (9 US DCs), see full VPN guide.
SaaS & API Services
SaaS applications need predictable performance and easy scaling. Start with 2 vCPU / 4GB for your application server. Separate your database to a managed service when you exceed 10K daily active users. Redis for session storage and job queues needs 1GB dedicated. API-heavy workloads benefit from providers with generous bandwidth and low-latency networking. Best picks: Vultr (API, hourly billing), Hetzner (price/performance), see full dev guide.
