Moongate - New Streamline Remote Control App for Android Users

[winter dew]

Moongate is a free, open-source Android app that gives you a full remote control interface for your Klipper 3D printer; live webcam, print controls, temperatures, and the complete Mainsail/Fluid UI, over your local network and automatically over the internet when you're away from home.

No Tailscale. No VPN setup. No subscriptions.

Looking for feedback from the voron community.

Moongate - New Streamline Remote Control App for Android Users

[fleet lichen]

Installed last night and worked great to monitor prints at work running after i left. Very easy to install and setup

[winter dew]

Thanks Sprincleez, for testing and reporting back to me the bugs you found, Everything has been fixed and is the reason now i am reaching out to people on here for more feedback and wider testing.

[timid salmon]

So hyped for this tbh

[winter dew]

added lots of cool stuff now 🙂

[shy ibex]

This is simply the best! The best remote control app I've ever seen!

[winter dew]

Thanks 🙂 i will have a big update coming next week regarding secuity. Rememeber do not share the QR code you generated with anyone as it will expose your printer network. I am working on adding layer 3 encryption soon 🙂 dont worry the app will remain free :]

[snow timber]

Oh this is cool!
Question: I try to avoid cloudflare stuff as most as possible (hard to do really but well 🤷) could a similiar thing done with a selfhosted instance of pangolin or simpler tailscale funnel?

[chrome trail]

fantastic, just tried on one printer and worked without any issue. I've been proxying my mainsail instances via a traefik docker container and serving them via cloudflare tunnel, this approach is night and day

[neat moth]

Love it. No bugs yet but is there a chance of Obtainium support? Think you just need a releases page but I could be wrong

[winter dew]

I am adding a database soon to improve security. I wanted to use tailscale originally but they don't have an API i can adopt into my app. So gonna just built my own.. for now cloudflare works just dont share the QR code with anyone haha.

Hello everyone!

I’ve been working hard on Version 4+ and there’s been a lot of progress tonight. Please make sure you install the latest plugin on Mainsail and download the newest APK.

Because the changes are significant, you’ll need to delete your current Moongate app before installing the update. The internal handling has been redesigned, especially around how the VPN pairing works.

Major update: fully secured tunnel
After scanning your code, the generated Moongate VPN link is now locked to your specific machine. It cannot be pinged or accessed by anyone else.

You can verify this after syncing:

Copy the URL again and try loading it

Even if you remove moongate-pair.html from the address, the machine will no longer appear

You should see “unauthorized”, which confirms the tunnel is now fully secure

This is a huge improvement in how Moongate handles device security.

If you find any bugs please do let me know, you can now also rename the printer when you go into the tile, i added a little rename icon 🙂

anyone else getting some new flags

[winter dew]

did you remove the old version and install the latest one?

if you can DM me your klippylog file i can fix this tonight.

[dense hemlock]

I didn't.

Will uninstall and re install

[winter dew]

Hello Safe, can you be more clear and what you did, did you run the uninstaller script from the github then did the install script at the top of the page?

send over me the log files klippy.log

[dense hemlock]

I just pressed the update button built into mansaill

Its a me issue for pressing the button

[chrome trail]

just tried to reinstall moongate but get this when launching the uninstaller

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Moongate Uninstaller
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

This will remove:
  • moongate-tunnel systemd service (cloudflared tunnel)
  • moongate-authproxy systemd service (v0.4 auth proxy)
  • Moongate Moonraker plugin
  • ~/moongate repository clone
  • ~/.config/moongate (tokens + secret key + v0.4 backup dir)
  • [moongate] entries in moonraker.conf
  • MOONGATE_PAIR macro from printer config
  • moongate-pair.html from Mainsail

And RESTORE (from ~/.config/moongate/v0.4-backup/ if present):
  • moonraker.conf — back to pre-v0.4 (Moonraker bound to 0.0.0.0)

Aborted.
curl: (23) Failure writing output to destination

after that I just rerun the installer and it's all working, but can't seem to view the camera stream from the printers list page tho

[winter dew]

is this via the tunnel or local mode?

[winter dew]

i will try and fix these issues tonight.. i knew something like this might pop up 🙂

[chrome trail]

Local

[winter dew]

thanks, i will do some bug testing tonight.. i missed a couple of things with the uninstaller and installer module.

[chrome trail]

Just tested remote and same issue btw

[winter dew]

yeah i can see the server is having issues finding the camera port on crowsnest.

at least the printer can be seen on the tunnel that is a big win for yesterday.

[winter dew]

Hello everyone! fixed a lot of stuff.. uninstall the app.. and update the plugin or remove and install it again. let me know how you guys get on!

[winter dew]

this should all be fixed now 🙂

[winter dew]

you are safe to update now 🙂

[chrome trail]

I'd update the readme to point to the latest version and not 0.4.2

[winter dew]

Apologies for that, i pushed an update late at night and forgot to add the finishing code for the plugin, Ill try not to slip up again XD

0.4.4 is the latest 🙂

[chrome trail]

Not a problem, was just suggesting that adding a dynamic link with a dynamic text pointing to the latest version would be less hassle to maintain. I updated via the app which I can attest works

[winter dew]

Sometimes i am pushing newer APKs for Pre release which i am testing on my end first.. if successful the github gets an update with the latest pointed to APK file.
