Reverse-engineered local API lets you own print data without Bambu's cloud.

Strengths
  • •Reverse-engineered undocumented local API allows bypassing manufacturer cloud lock-in completely.
  • •Proxy mode enables remote printing with TLS without sending data to Bambu.
  • •Integrates with Home Assistant and Tasmota for smart power management automation.
Weaknesses
  • •Relies on reverse-engineered protocol that firmware updates could break unexpectedly.
  • •Limited to Bambu Lab ecosystem, useless for other printer brands like Prusa.

Post Description

Bambu makes great hardware, but your data lives in their cloud and there's no way to export it. When a print finishes, the job is basically gone from any useful record-keeping perspective.

BamBuddy fixes that by running on your own machine and tapping into the printer's local MQTT interface — so it captures everything as it happens: thumbnails, filament usage, timing, slicer settings. You end up with a fully searchable archive of your print history that's entirely yours, works offline, and never touches Bambu's servers.

The catch: their local API is undocumented, so a lot of the early work was reverse-engineering the protocol. That's still ongoing as firmware updates occasionally break things.

Stack: TypeScript, self-hosted, ~700 stars, small but active contributor community.

PrintStack – macOS virtual printer to queue and merge PDFs

You send prints to a local virtual printer, inspect a smart queue (rename items, check page counts), drag in extra PDFs and then merge or print the whole stack — exact workflow-level tooling that saves annoying manual merging. The app is small, privacy-friendly (developer claims no data collection) and includes useful extras like a log viewer, but the core idea is familiar and the free tier’s 5-document limit feels deliberately gating without compelling advanced features shown on the listing.
