Nexus Guard
Monitoring for indie hackers and solo founders
Have you ever checked your Stripe dashboard and realized revenue dropped 40%… and you had NO IDEA why?
That happened to me. My webhook silently stopped firing. Users got errors at checkout. My site showed "200 OK." But behind the scenes, I was bleeding subscribers for three days before I noticed.
$2,400 in lost revenue. Gone.
I talked to 50+ solo founders and heard the same story:
"My sitemap returned 404 for a week before I noticed."
"A build update stripped all my meta tags — traffic dropped 60%."
"My payment provider changed their API, and I only found out from a customer email."
Existing tools don't help solo founders. PagerDuty, Datadog, Grafana — they're built for teams with DevOps. They false-positive constantly. They're expensive.
What solo founders actually need:
"Is my checkout working?" — answered in real-time
"Did my SEO just drop?" — alerted immediately
"Is my API still returning the right responses?" — caught on deploy
So I built Nexus Guard 🛡️
It monitors your side project every 60 seconds for:
Uptime — Global checks, no false positives
SEO health — Meta tags, sitemaps, 404 spikes
Checkout flows — Real transaction simulations
API integrity — Latency, errors, response shape
When something breaks, you get an alert within 60 seconds.
Pricing: $19/mo per project. Setup: 5 minutes. No code changes. Any stack.
I'm looking for 10 beta testers. 3 months free + lifetime 20% discount.

About
I built Nexus Guard because I know how painful it is to discover a problem after it has already cost you customers and revenue. A checkout can fail, an API can break, or SEO can suddenly drop.

the simple does exist it's called
healthchecks ioThe $2,400 loss and 50+ conversations make the problem credible. Which monitoring failure are beta users most willing to pay to prevent?
The revenue-impacting failure angle is the clearest paid-use signal so far. If you’re open to it, what’s the best email to reach you on?
Thanks! I’ve just sent it over.
Looking forward to hearing your thoughts whenever you have a chance.
