3D printer fleet monitor. Self-hosted. No lock-in.
Proven on real production 3D-printer fleets — Klipper, OctoPrint, Prusa Connect, and more. The same architecture reaches into Bambu, CNC, and other machine types, live today in alpha. Flat-rate pricing. No per-machine fees. You own your data.
Free forever for up to 5 machines · No credit card · AGPL-3.0 licensed — never locked in.

Paid tiers differ only by how many machines you can connect — never by features. Pick your fleet size.
OEE Dashboard
Track Overall Equipment Effectiveness per machine — availability, performance, quality — in real time.
Floor Plan Overlay
Drag-and-drop visual layout of your shop floor with live machine status — rarely found outside enterprise systems costing thousands a year.
Signed Webhooks & Alerts
Fire HMAC-SHA256-signed webhooks on any machine event — temperature, errors, job complete. Integrate with Slack, PagerDuty, or any HTTP endpoint, tamper-evident.
RBAC + SSO + Audit
Role-based access control with JWT — admin, operator, or viewer per user, on every paid tier. SSO via OIDC/LDAP (beta) and a full audit log included at every tier above Free.
18 Protocol Adapters — 6 Proven, 12 Alpha
Proven on 3D printers: Klipper/Moonraker, OctoPrint, Duet, Prusa Connect, Marlin, FluidNC. Bambu Lab uses reverse-engineered APIs (unverified). The same architecture reaches into CNC and more — MQTT, GRBL, LinuxCNC, Mach3/4, OPC-UA, Sinumerik, Haas, Fanuc, Fadal, OpenPnP — real code, alpha until verified against your specific hardware. ⚠️ CNC emergency-stop is not guaranteed on unverified controllers.
Extensible by Design
AGPL-3.0 licensed. Write your own adapter in Python with the base class. Any machine with an HTTP or WebSocket API is supported.
Why switch to MEMAR?
| Tool | Price (10 machines) | Self-hosted | Multi-type | MEMAR savings |
|---|---|---|---|---|
| MEMAR Pro | $49/mo flat | ✅ | ✅ | — |
| SimplyPrint | $299/mo enterprise | ❌ | ❌ | $250/mo saved |
No activation fee. No per-machine charges. You own your data. Comparison uses SimplyPrint's Enterprise tier — the one carrying SSO and audit logs, which every MEMAR paid tier includes. Their cheaper per-printer plans (from ~$40/mo for 10 printers) don't.
See what you'd save.
Drag to match your fleet. MEMAR is flat-rate; most monitoring tools bill per machine — so the gap only widens as you scale.
