FAQ

Why does UptimeRobot offer 50 free monitors but ToolKnife only 3?

UptimeRobot is a dedicated monitoring service. Monitoring is their entire product, so they can afford generous free tiers. ToolKnife bundles monitoring with 290+ other tools, so per-feature limits are tighter.

Can ToolKnife replace UptimeRobot?

For basic HTTP monitoring with email/webhook alerts and a status page, yes. For multi-region checks, SSL monitoring, keyword monitoring, or native Slack integration, UptimeRobot is more capable.

Does ToolKnife check from multiple locations?

Not yet. ToolKnife checks from a single Hetzner region. Multi-region checks are planned. UptimeRobot checks from multiple global locations, reducing false positives from regional network issues.
