About Saturn

Making scheduled job reliability observable and proactive

Our Mission

Cron jobs run the internet—database backups, ETL pipelines, cache warming, report generation—yet they fail silently in the dark. Saturn brings them into the light with statistical anomaly detection that catches slowdowns before they become failures.

We believe DevOps and SRE teams deserve better than "it ran at some point, probably." They deserve confidence.

The Problem We're Solving

Every night, thousands of critical cron jobs fail silently:

  • Database backups that never complete (you discover this during a restore)
  • ETL pipelines that take 3 hours instead of 30 minutes (downstream systems starve)
  • Cache warmers that timeout (your app serves stale data)
  • Report generators that skip (executives make decisions on yesterday's numbers)

You don't need another ping service. You need a partner that understands reliability.

What Makes Saturn Different

1. Statistical Anomaly Detection (Unique)

We're the only cron monitoring platform with Welford's online algorithm for incremental statistics:

  • Baseline established in just 10 runs
  • Z-score analysis triggers incidents when runtime exceeds 3σ (99.7% confidence)
  • Memory-efficient: O(1) usage (40 bytes per monitor, not 40KB of historical data)
  • Catches regressions early: "Your backup is 2× slower than usual—investigate before it fails"

2. Kubernetes & WordPress Integrations (Unique)

  • Kubernetes Sidecar (Go container): Automatically wraps CronJobs, deploys via Helm in 5 minutes
  • WordPress Plugin (PHP): Monitors wp-cron (notorious for breaking on low-traffic sites)

Nobody else has these. We built them because 43% of websites run WordPress, and Kubernetes is the infrastructure standard.

3. Health Scoring System (Unique)

Every monitor gets a 0-100 health score with letter grade (A-F) based on:

  • Uptime percentage (last 30 days)
  • MTBF (Mean Time Between Failures)
  • MTTR (Mean Time To Resolution)
  • Anomaly frequency
  • Incident severity

Our Values

Reliability > Vanity Metrics

Health scores over ping counts. MTBF/MTTR over uptime percentages. Actionable insights over noise.

Developer Empathy

CLI-first, API-first, infrastructure-as-code ready. No magic, no lock-in.

Clarity Over Cleverness

We document how anomaly detection works. Rate limits are clear. No hidden fees, no BS.

Security by Default

TLS 1.3, SHA-256 token hashing, row-level security, automatic redaction. No shortcuts.
