Why I built PingKeeper - a website monitoring tool

I started building PingKeeper after looking at the uptime monitoring space and noticing a gap: most tools either have no real free tier at all (Pingdom starts around $10-15/month, no permanent free plan) or force a steep jump to paid the moment you outgrow a small free tier (StatusCake caps free at 10 monitors checked every 5 minutes, then jumps to $20+/month for the next step).

I wanted to build something with a genuinely usable free tier from the start — 10 monitors, checked every 4 minutes, no credit card required — with alerts sent to Discord or Slack, since that's where most small teams and solo builders actually watch for notifications, not email. The Pro plan drops checks to 1-minute intervals and adds Telegram, at one flat monthly price instead of a per-monitor pricing table that climbs as you scale.

I'm building this solo and it's still early. If you try it, I'd genuinely appreciate knowing what's missing or what breaks — happy to talk through any of it.
