Meet Saryno: Observability That Just Works

I've been quietly building Saryno as a side project — and I think it's time to talk about what it actually is.

The Problem

Running production infrastructure means drowning in questions. Why is this endpoint slow? Where did that error come from? What's consuming all the memory on node 2? Answering these questions usually means stitching together logs from one tool, metrics from another, and traces from a third — each with its own agent, its own pricing model, and its own way of doing things.

Existing solutions like Datadog work, but they're expensive, US-centric, and frankly complex to set up if you're a small team or a solo developer.

What Saryno Is

Saryno is a self-contained observability platform. You install a lightweight agent on your servers, and it starts collecting metrics, logs, and traces automatically — no complex configuration, no vendor lock-in, no surprise bills.

The Agent

The Saryno agent installs in seconds:

curl -fsSL http://get.saryno.com/install.sh | SARYNO_API_KEY=<your-api-key> sh

Once running, it registers with the platform and begins collecting system-level telemetry — CPU, memory, disk, network — as well as application logs and distributed traces from your services. Configuration is pulled automatically from the backend, so you don't need to manage config files across machines.

The Node.js SDK

For application-level observability, Saryno ships `@saryno/tracer` — an npm package that instruments your Node.js apps and emits traces directly to the Saryno platform using OpenTelemetry.

npm install @saryno/tracer

It's built on top of the OpenTelemetry standard, which means you're not locked in — your instrumentation works with the spec, not just with Saryno.

What You Get

Metrics — system and application metrics, visualised in real time

Logs — fully searchable log ingestion, including query parameters

Traces — basic distributed tracing to follow requests across services

Database Monitoring — early-stage visibility into PostgreSQL queries and slow statements

Alerts — notifications via Slack, Discord, or webhooks

Who It's For

Saryno is built for developers and small engineering teams who want production-grade observability without the enterprise price tag or the complexity.

Still Early

Saryno is an active side project. Things are moving fast, and the roadmap is shaped by real user feedback. If you have ideas, feature requests, or just want to follow along — you can submit feedback directly from inside the app.
