Hey PH! I'm Cory, and I built PingSentry because I got tired of overpriced monitoring tools.
I was running a side project and paying $50+/mo for Pingdom just to know if my site was up. All I needed was "is it online?" and "tell me if it breaks." I didn't need APM, distributed tracing, or a 47-page dashboard.
So I built PingSentry — simple uptime monitoring that does one thing well.
The stack is intentionally minimal: Node.js, Express, SQLite, running on a single DigitalOcean droplet. No VC funding, no team, just me shipping code.
What makes it different:
- Free tier with 10 monitors (no credit card)
- 30-second checks on Business plan
- Alerts via email, Slack, Discord, or webhooks
- A live demo with real data — try it before you sign up
I'd love your feedback. What would make you switch from your current monitoring tool?
