Backend Monitoring

Find the slow route before your users do

Statvisor tracks every API request your backend handles - latency, error rates, and request volume per route. You see exactly which endpoint is hurting your product before a user complains about it.

What you get

Everything you need to understand how your API performs in production, without learning a new tool or reading docs for a week.

Latency at every percentile

P50, P95, and P99 means you see not just the average but the worst 5% and 1% of requests. This is where real user pain hides.

Errors that actually matter

Statvisor separates health errors from expected ones. A 404 is not a crisis. A 500 spike is.

Drill into any endpoint

Click any route to see its status code breakdown, request volume over time, and the last 50 errors with full context.

Spot regressions instantly

Every chart shows trends over time. A deploy that slowed down your checkout route shows up immediately.

This is all your developer does

Your developer adds one middleware line. That is it. No infrastructure to manage, nothing to maintain.

# install the SDK
npm install @statvisor/sdk

import { statvisor } from "@statvisor/sdk"

// Add one line to your Express app
app.use(statvisor({ apiKey: "vl_your_key" }));

// Every route is now tracked automatically

Works with Express, Fastify, NestJS, Hono, Next.js, and Cloudflare Workers.
