In Development

Meet Argos,
the all-seeing observer.

Know when your Node.js app starts misbehaving — before your users do. Event loop starvation, memory anomalies, behavioral drift. Argos catches the symptoms.

We'll notify you when Argos is ready. No spam, ever.

"In Greek mythology, Argos Panoptes was the all-seeing giant with a hundred eyes — never all closed at once. Our Argos watches your runtime with the same vigilance."

Four Layers of Protection

Argos uses a multi-layer observation architecture to catch what single-threaded monitors miss.

LAYER 1

Worker Thread Observer

Independent event loop that detects main thread starvation within 3 seconds. Uses SharedArrayBuffer heartbeat — immune to event loop blocks.

LAYER 2

Adaptive Sampling

Baseline mode: 5s intervals at <0.1% CPU. Burst mode: 100ms intervals when anomaly detected. Auto-escalates and cools down.

LAYER 3

Ring Buffer

Fixed-size circular buffer with 1000 signals. O(1) writes, retroactive analysis. See what happened before the incident.

LAYER 4 Optional

Native Watchdog

libuv timer outside JS event loop. Emergency alerts for extreme timeouts (>10s). Last line of defense.

What Argos Observes

Five observation axes covering runtime health, event loop behavior, and integrity.

Latency, starvation, microtasks

worker

Quick Integration

app.ts

import { createArgos } from '@argos/core'

const argos = createArgos({
  sink: { emit: (signal) => console.log(signal) }
})

argos.start()

// Your app continues as normal
// Argos watches silently
