One dashboard for every printer. Intelligent alerts that fire on real failures, not noise. Built for operators running OctoPrint and Klipper, not enterprise procurement teams.

Why PrintSentry
!

Alerts, not noise

Operator-tuned heuristics fire on real problems. Thermal anomaly detection, progress stalls, disconnect events. Each rule has severity, threshold, and cooldown. No "your printer beeped" spam.

</>

OctoPrint + Klipper native

First-class support for OctoPrint REST API and Moonraker WebSocket. Connect with your existing API key. No proprietary bridge hardware, no vendor lock-in. Prusa Connect coming next.

30-second polling

State pulled every 30 seconds from every printer. Progress, temperature, job status, error flags. If something goes wrong at 3am, you know within a minute, not the next morning.

#

Email + Discord dispatch

Alerts go where you already look. Email for critical failures, Discord webhook for your print-farm channel. SMS on paid tiers. No app to install, no push notification fatigue.

Default alert rules, tuned by operators

These ship out of the box. Customize thresholds, add your own, or disable what you don't need.

Critical Hotend temp deviates from target by >15 C during steady-state 30s sustained
High Printer API unreachable (offline/disconnected) 90s consecutive
High Print state transitions to error or cancelled mid-job Immediate
Medium Progress unchanged while printer reports "printing" 10min stall
Medium Filament runout sensor triggered (where supported) Immediate

Built by operators, for operators.

PrintSentry exists because we ran a farm, watched tabs, and missed failures overnight. The alerts you get should be the alerts that matter.
