The short version

  • Only Site24x7 has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog consumption-based pricing model makes costs hard to predict and can scale quickly; Site24x7 website and infrastructure monitoring are sold as separate plan tracks; the entry Web Uptime plan ($9/month annual) covers only 25 websites and does not include server monitoring, which requires a separate Lite infrastructure plan
