  • High-concurrency query support (hundreds of thousands QPS) requires significant cluster infrastructure investment

ProtonVPN

  • Free plan limited to one device at a time
  • Free plan restricted to 10 countries with random selection
  • Pricing amounts not clearly published; shown as variable
