Features

Everything you need to monitor your API

Built for backend developers who want observability without the ops overhead.

One-line setup

Install the SDK, add one middleware call. Every route is automatically instrumented — no decorators, no config files.

Real-time analytics

P50, P95, P99 latency per route. Error rates, request volume, and status code breakdowns — updated in real time.

Works with any backend

Express, FastAPI, Django, Fastify, NestJS, Hono, Next.js and more. If it handles HTTP, Statvisor can monitor it.

Zero performance impact

The SDK captures timing and batches events in the background. Your handlers are never blocked or slowed down.

Route-level visibility

See every endpoint separately. Instantly spot which route is slow, erroring, or getting hammered with traffic.

FAQ

Common questions

Does the SDK slow down my API?

No. The SDK records timing before and after your handler, then queues events in memory. Flushing happens asynchronously in the background — your request path is never blocked.

What frameworks does Statvisor support?

Express, Fastify, Hono, NestJS, and Next.js on Node.js. We also support Django and FastAPI on Python.

How long is data retained?

Free plan retains data for 7 days. Pro plan retains data for 30 days. Data is automatically pruned via a scheduled cron job.

Can I cancel my Pro subscription anytime?

Yes. You can cancel anytime from the billing portal in your settings. You retain Pro access until the end of your billing period.

Is my API data private?

Yes. All data is scoped to your account using row-level security. No other user can see your API events or project data.
