Introduction

Meet Rytena

Production observability for Node.js. Rytena watches your services, catches problems in real time, and turns every incident into a fix you can merge.

Traditional monitoring tools show you graphs. When your app breaks, they page you and hand you a stack trace. You debug, you fix, you deploy.

Rytena is different. It runs inside your Node.js process, learns your app's baseline, and detects anomalies as they happen. When something goes wrong, it doesn't just alert you — it analyzes the root cause and produces a ready-to-review fix.

Rytena is currently in beta. Free forever for personal use during the beta period.

What Rytena does today

  • Detects memory leaks in Node.js applications in real time
  • Identifies the exact file, function, and line responsible
  • Generates a plain-English explanation of the root cause
  • Suggests a code fix based on the actual leak pattern
  • Sends email alerts when leaks are detected
  • Provides a live dashboard for all your monitored processes

The three-minute install

Rytena works with any Node.js application. There are no code changes required beyond initializing the agent.

bash
npm install rytena-agent
server.js
const { Rytena } = require('rytena-agent')

Rytena.init({
  apiKey: process.env.RYTENA_API_KEY
})

That's the entire integration. The agent connects to Rytena's backend, streams memory metrics every 10 seconds, and runs deep analysis when it detects a leak pattern.

How Rytena compares

Rytena is not a replacement for Datadog or Sentry. It's a focused tool that does one thing better than they do: production memory analysis for Node.js with actionable output.

  • Traditional APM — shows you dashboards, expects you to interpret them
  • Error tracking — captures crashes after they happen
  • Rytena — catches problems before they crash and hands you the fix
