OctoPrint vs PrusaSlicer

OctoPrint is free, open-source software that provides a web interface for controlling consumer 3D printers. From a browser, users can check print progress and temperatures, move the print head, and start, stop, or pause a job. The interface can show an embedded webcam feed and a visualization of the G-code being printed. A plugin system connects to OctoPrint’s official plugin repository for installation. Other listed features include timelapse recording, STL slicing, access controls, system commands, and event hooks. The site says it works out of the box with most consumer printers. Hosting options include Raspberry Pi, Android phone, Docker, Linux, Windows, and manual Mac installation. For OctoPi, Raspberry Pi 3B, 3B+, 4B, or Zero 2 is recommended; other hardware setups are not officially supported. Anonymous access is denied by default, and the documentation recommends a VPN or additional protection for internet access. OctoPrint does not control the embedded webcam, so its access controls cannot limit access to the webcam URL.

PrusaSlicer converts a 3D model into files for a 3D printer. It is free, open-source software based on the Slic3r project, and it performs slicing on the user's computer without requiring an account. The listed desktop downloads are for Windows, macOS, and Linux; the Windows download requires Windows 10 or later. Simple, Advanced, and Expert modes offer different levels of control. Users can create organic-shaped supports, paint support zones, and paint material regions. The software supports MMU3 and multi-extruder setups, plus layer-by-layer filament changes for basic multicolor prints. Its cut tool can divide a model and add alignment pins at the join. A built-in Printables.com browser supports finding and importing models for slicing. Printer connections include Prusa Connect, Klipper, and OctoPrint. A command-line interface supports batch slicing and custom manufacturing pipelines. Models, profiles, and G-code stay on the computer unless sent elsewhere. Prusa provides a support section in its Knowledge Base.
