About this app

K2 Companion is the independent remote monitoring and control app for the
Creality K2, K2 Plus and K2 Pro 3D printers. Watch your prints, control your
printer and manage your CFS from anywhere, with no Creality Cloud account and
no sign in.

Built by a working 3D print workshop, for people who want full control of
their own printer without handing it to the cloud.

FEATURES
- Live camera view of your Creality K2 while you print, at home or away
- Real time temperatures, progress and print status on a clean dashboard
- Full remote control: pause, resume, stop, move axes, chamber light
- CFS multi colour filament mapping, change a colour without re slicing
- Print tuning: pressure advance, speed and acceleration, live
- Bed mesh view and Creality AI failure detection controls
- Cancel individual objects mid print
- Config file editor with automatic backups
- G code and Klipper console
- Push notifications when a print finishes or an error is detected
- Works on your local network, or securely from anywhere with remote access

NO CREALITY CLOUD ACCOUNT REQUIRED
Connects directly to your printer over your own network. Remote access uses a
private, self hosted relay, not Creality Cloud. Your printer stays yours.

WORKS WITH
Creality K2, K2 Plus and K2 Pro. Built on Klipper and Moonraker.

One time purchase. No subscription. Optional one time unlock for managing
multiple printers.
MONITOR
• Live print status: progress, layer, time remaining and a thumbnail of what's printing
• Real-time nozzle, bed and chamber temperatures
• Built-in camera view so you can watch the print

CONTROL
• Pause, resume, cancel and emergency stop
• Fans, lights, print speed and flow, Z-offset baby-stepping, homing, filament load/unload

• Upload G-code and start a print straight from your phone

RICHER KLIPPER TOOLS
• Bed-mesh heatmap — see your bed levelling at a glance
• Browse, reprint and manage the files already on your printer
• One-tap Klipper restart and recovery

REMOTE ACCESS, FROM ANYWHERE
• Securely reach your printer when you're away from home — no router setup, no port forwarding
• Per-device security, encrypted in transit
• Your data stays yours: there's no account, and we don't store your printer data

PRIVATE BY DESIGN
K2 Companion is local-first. On your home network it talks directly to your printer, stores everything on your device, and uses no advertising or tracking. Optional remote access routes through a secure relay that forwards your data without keeping it.

Pay once. Own it. No monthly fees, ever.

Requires a Creality K2 (or K2-family) 3D printer on your network.

What’s new

Current layer is now shown during prints. Progress and remaining time now use the K2's native telemetry for closer agreement with the printer and Creality Cloud. Active-job thumbnails load more reliably, including touchscreen-started jobs. Also adds Quit controls, smart-plug support for Tasmota, Shelly and TP-Link Kasa, and layout fixes for narrow screens.
