The short version

  • Each has a real cost: Restate the runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone.; UptimeRobot free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Restate

  • The runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone.
  • Restate Cloud jumps from a free fifty thousand actions straight to 300 US dollars a month for twenty million, so a workload sitting at a few hundred thousand actions pays enterprise-shaped money for hobby-shaped volume.
  • It is a young project against Temporal’s established base, so hiring engineers who already know it is unrealistic and the answer to most questions is in the docs rather than on Stack Overflow.
  • The programming model requires structuring code around durable handlers and virtual objects, which is a genuine rewrite for existing services rather than a library you add.
  • The single-binary simplicity that makes small deployments cheap also means fewer operational knobs at very large scale than a system designed as separable components.

UptimeRobot

  • Free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale
  • Team plan includes only 3 seats; additional seats are not covered in the base $41/$35 per month price
  • Enterprise pricing and faster-than-15-second intervals are custom and require contacting sales
