You built the product. You deployed it. Now it lives in production, and you have almost no idea what it does at 3am. That gap between running and observable is where a solo founder loses sleep and, eventually, users.
What Belongs in a Lean Monitoring Stack?
Ignore the enterprise checklist. A small product needs four signals, and nothing more until it grows. We have shipped enough of these to know the gap by heart.
| Signal | What it answers | How to read it |
|---|---|---|
| Uptime | Is it reachable right now? | An external ping plus who gets paged |
| Latency | Which routes are slow? | P95 and P99 per route, not the average |
| Errors | What throws, since which deploy? | Error rate on the same timeline as latency |
| Real users | Who visits, does it feel fast? | Cookieless analytics and Web Vitals |
If you want concrete picks: Better Stack or a plain cron ping for uptime, Statvisor for per-route latency and errors, GlitchTip or Sentry if you prefer a dedicated crash tracker, and a cookieless analytics tool for the real-user view. You can also collapse most of that into a single flat-priced dashboard. The brand names matter less than the principle: every signal needs an owner and one place you actually look, or it quietly stops being watched.
Stop Gluing Five Tools Together
The classic indie stack is a graveyard of free tiers: Pingdom for uptime, Sentry for errors, Mixpanel for product analytics, a log drain somewhere, and a spreadsheet holding it together. Five logins, five bills, and no single view.
The goal is not more tools. It is one place where a slow route, a spike in errors, and a drop in visitors line up on the same clock.
How Should You Read the Numbers?
Averages will comfort you into missing the tail. Track P95 and P99 per route, and grade page speed from real visitors, not a synthetic ping. The P50 vs P95 vs P99 guide covers why the median flatters you. The same discipline applies to analytics: a conversion rate computed only from consenting visitors is a number you cannot act on. Read every signal from real traffic, at the tail, and you spend your limited hours fixing what users actually feel instead of what a dashboard average implies.
How Do You Wire Up the Stack?
A JS-native tool covers backend and browser from one key. Add the server adapter and drop the analytics component into your layout:
import { Statvisor } from "@statvisor/sdk";
const sv = new Statvisor({ apiKey: process.env.STATVISOR_API_KEY! });
app.use(sv.express());
// frontend: <StatvisorAnalytics frontendKey="vl_fe_..." /> in your root layoutStatvisor folds uptime, per-route latency, errors, and cookieless real-user analytics into one flat-priced dashboard, so the whole indie stack collapses into a single tab.
Grow Into More Later
Start with the four signals. When the product earns it, add tracing and deeper log search. Until then, keep it lean: see flat-rate vs usage-based pricing so the bill scales slower than the app.

Statvisor gives you latency percentiles, error rates, and request volume for every route, in minutes, not days.
