I’m Casper — product & engineering from Denmark —, and for the last months I’ve been building a super small tool to solve a problem that kept coming up in my own projects.
Some of my side projects needed basic uptime checks, but everything I tried felt heavier than the problem required:
• too many features
• dashboards packed with stuff I didn’t need
• enterprise-style UX
• complicated onboarding
• pricing that felt out of place for a simple monitor
I just wanted something that answered one question:
“Is my site or API up right now?”
So I built the tool I wish existed:
Web-Alert.io — a clean, minimal uptime & API monitoring service designed for indie hackers, small projects, and anyone who wants fast, simple checks.
⸻
🟣 What Web-alert.io Does
• Monitor websites + API endpoints
• Send email alerts the moment something breaks
• Track response times
• Check SSL certificate status
• Show uptime history in a simple dashboard
• Set up monitors in under 60 seconds
This isn’t meant to compete with enterprise tools — it’s meant to be lightweight, fast, and easy to understand.

💡 Why I Built It
Because almost every uptime tool I tried made me feel like I was entering a cockpit when all I needed was a light that turns red when something is wrong.
I wanted:
• simple setup
• clean UI
• predictable alerts
• a fair free plan
• and no noise
Eventually I realized the simplest way forward was to just build it myself.
⸻
🧪 What I’m Looking for
The project is live, but very early.
If you check it out, I’d love feedback on:
• onboarding
• clarity
• UX flow
• what feels confusing
• what features you’d actually want
• anything that’s missing or feels unnecessary
This kind of early feedback is insanely helpful.

There’s a free plan with up to 5 monitors — no credit card needed.

🙌 Thanks!
If you’ve built something similar or have ideas from your own uptime/monitoring experience, I’d love to hear what you learned.
Happy to answer questions about the build, architecture, UX decisions, or anything else.
