If you own a Bambu Lab printer but would rather not send each print job through Bambu’s servers, Bambuddy is trying to take that responsibility back into your own hands.
Bambuddy describes itself as an open-source. self-hosted. cloud-free central command that provides a local alternative to Bambu Lab’s official cloud services. In practical terms. it replaces the need to rely on Bambu’s servers for slicing. printing. and monitoring—so everything can run under full local control.
The project is built for scale, too. Bambuddy can manage anywhere from one to forty Bambu Lab printers, with its role extending beyond simple job sending. It aims to function as a full-featured control panel and management center for that entire set of printers.
The setup is designed around an important shift: putting the printers into LAN-only mode. Once that’s done, the printers disable cloud functionality, including remote access. From there, users enable Developer Mode so external software can control printer functions via a machine API. Then, the printers can be added to Bambuddy.
Bambuddy itself runs on Linux, macOS, or Windows, and the project points to a Raspberry Pi as a common install target—an option that will feel familiar to anyone used to self-hosting on small, always-on boxes.
Bambu Lab’s printers are widely viewed as high quality. and the convenience of Bambu Lab’s software and official app is part of the appeal. But Bambuddy’s pitch is pointed: every print job going through Bambu’s servers and a software architecture that. as Bambuddy frames it. frustrates home-grown solutions. The project also cites AGPLv3 violations and “heavy-handed legal behavior” as part of the motivation behind building a replacement.
The feature set is described as extensive, including an integrated slicer and a proxy mode for remote access. For anyone who worries that open-source alternatives can be intimidating. Bambuddy’s website offers a live sandbox demo with simulated printers—meant to let people learn by clicking around without dealing with real hardware or real consequences.
What Bambuddy is really asking for is a simple trade: less convenience, more control. For owners who don’t want their print jobs passing through an external server for every task. the appeal is immediate. For those who value the official app experience. Bambuddy’s existence is a reminder that the line between “easy” and “open” can matter as much as the hardware itself.

So does this stop the printer from sending stuff to the cloud or is that just marketing?
I don’t get why they’d disable the built-in app stuff like… isn’t that the whole point? Also “Developer Mode” sounds like something that breaks if you look at it wrong.
If it’s “cloud-free” then couldn’t you still update firmware over the internet? Like I saw another post and it said it still calls home, so idk. But I guess Raspberry Pi makes it more DIY so maybe that’s the goal.
This whole thing about AGPL violations and legal behavior… sounds like Bambu really messed up and now people are trying to dodge the servers. I’m not saying open source is bad but self-hosting on Windows is gonna be a headache for most folks. Meanwhile my friend just clicks print and it works, so why would anyone change that?
