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 $2,400 loss and 50+ conversations make the problem credible. Which monitoring failure are beta users most willing to pay to prevent?
