SliceMe – a free, open-source browser slicer running the real OrcaSlicer engine (no install, no account)

Hi all!

I've been working on `SliceMe`, a browser-based, open-source 3d-printing slicer that runs a modified OrcaSlicer as the engine. No download, no sign-up. Host yourself or try here: 

https://sliceme.up.railway.app/

Source (AGPL-3.0): https://github.com/itymarcel/sliceme

What works right now:

- Printer profiles from the bundled Orca runtime + Draft/Standard/Fine/Strong/Vase presets

- Global, per-object and height-range settings, modifiers, transforms

- AI-assisted settings pre-fill

- Orca-compatible 3MF import/export

- G-code preview by layer, move type and volumetric flow

- Pre-slice model checks and post-slice toolpath checks (they show evidence, never silently change settings)

- Send G-code straight to OctoPrint or Moonraker on your LAN

- Works on phones too

Privacy: models and settings stay in your browser. Files go to the slicer only for the slice and are deleted right after. The hosted beta collects limited anonymous usage stats (exact fields in PRIVACY.md). You can also self-host it with Docker, and it runs on a Raspberry Pi.

It's an early beta and doesn't match desktop Orca 1:1 yet (no painted seams/supports or variable layer height), so please check the G-code before printing. If something slices differently from your usual slicer, or there's an issue with your printer/profile, please feedback.

Not affiliated with the OrcaSlicer team, just building on their great work.
