About Statvisor

Monitoring built for developers who ship alone — or nearly alone.

Statvisor is a JavaScript API monitoring and frontend analytics tool. One SDK, one dashboard — covering backend performance, real-user Web Vitals, page analytics, and structured logs. Built for the developer who doesn't have a DevOps team but still needs to know when something breaks at 2am.

Datadog is for enterprise. Sentry solves a different problem. Most solo developers are flying blind.

Datadog charges per host, per module, and per seat. A solo developer monitoring one production app pays $31/month for APM before logging a single line — and the bill typically reaches $200–$800/month within a year once you add logs and database monitoring.

Sentry is excellent for error tracking but doesn't give you per-route latency percentiles, request volume trends, or frontend Web Vitals in one place. New Relic requires an agent. Grafana requires infrastructure you have to maintain.

The result: most solo developers and small teams go without real monitoring — or spend hours stitching together tools that were each designed for larger teams.

Statvisor

All features. No per-host charges.

Flat pricing

Works with the stack you already use

The Statvisor SDK ships adapters for every major JavaScript backend framework and both React and vanilla browser environments. There's no agent to deploy, no sidecar to configure, and no infrastructure to maintain.

Who Statvisor is built for

25% of developers work at companies with fewer than 20 people. Almost 1 in 5 is an independent contractor. These are the people Statvisor is designed for.

Solo developers

Shipping a SaaS, API, or app on Vercel, Railway, Render, or a VPS — without a dedicated DevOps person.

Small engineering teams

2–5 engineers who need production visibility without committing to a per-seat, per-host enterprise contract.

Technical founders

Founders who write code and care about uptime, latency, and user metrics — not just revenue dashboards.

Freelancers and agencies

Developers building production apps for clients who need monitoring without adding complexity to every deployment.

How it works

From npm install to live production data in under two minutes. Full setup guides in the docs.

1

Install the SDK

One package. Works with every major JavaScript framework.

npm install @statvisor/sdk
2

Add one middleware line

No YAML. No agents. No config files.

app.use(statvisor.express({ apiKey: process.env.STATVISOR_API_KEY }))
3

See your API in real time

Per-route P50/P95/P99 latency, error rates, and request volume appear in your dashboard within seconds of the first request.

Flat pricing. No per-host charges. No module creep.

Enterprise monitoring tools make money by charging separately for each product (APM, logs, RUM, traces), billing per host so costs scale with traffic spikes, and using overages to turn an affordable bill into an unpredictable one.

Statvisor doesn't do any of that. Every feature is included in every plan. You know what you'll pay before the month starts, and it doesn't change because you pushed to production during a traffic spike.

We write about monitoring for small teams

The Statvisor blog covers API monitoring, frontend performance, observability on a budget, and practical debugging — written from the perspective of developers who ship and maintain production apps themselves.
