NetworkAI vs UptimeRobot
UptimeRobot is the default first monitoring tool for a reason — its free tier is huge. Here's where the two products actually differ once certificate renewal is the thing you care about.

The honest take
If you want one free tool that watches everything at a shallow level, UptimeRobot's 50-monitor free tier is hard to beat and we're not trying to replace it. NetworkAI exists for the specific failure mode UptimeRobot doesn't model: a renewal that silently didn't happen. If uptime pings are your main need, run both — they're not mutually exclusive.
