My Recommendation

For most users: Start with WizStatus for the 1-minute intervals and SSL monitoring, or Freshping if you need more monitors with fast checks.

For hobbyists with many sites: UptimeRobot's 50 monitors is hard to beat.

For technical users: Uptime Kuma offers the most flexibility and features at no cost.

The "best" free tool depends on your priorities:

• Speed of detection: WizStatus or Freshping
• Number of monitors: UptimeRobot or Freshping
