In their own words
AstroPrint
AstroPrint is a platform for managing 3D printers and printer fleets. Its cloud library stores STL and G-code files, and users can slice designs in a browser. A cloud dashboard tool generates printable models from text prompts. Users can monitor prints and remotely pause, resume, or cancel them from a computer or smartphone; analytics cover filament use, printer operating hours, and print success rates. Printers can connect through AstroBox Touch, AstroBox Gateway, a self-built AstroBox, or the OctoPrint plugin. The mobile app can search Thingiverse designs and start prints. AstroPrint Desktop is listed for Mac OS X, Windows, and Linux, alongside Android, iOS, web, API, and self-hosted platforms. Klipper is supported for slicing only, and live video streaming is not available in the mobile app; a browser is needed for that. The free Basic plan includes 2 printers, 1 user, and 1GB file storage. Premium costs $9.90/mo and includes the first 5 printers, with each additional printer costing $5.
KISSlicer
KISSlicer turns STL files into printer-ready G-code and is a slicer, not a printer control app. Four Profile Wizards help configure printer, material, style, and support settings. Automatic support generation, resin slicing, and variable layer height are supported. The free plan costs nothing and allows multi-extruder printers to be used, but only one extruder can be selected for a print. Pro costs $42, paid once and enables multi-material printing, with extruders assignable to the raft, support, model, and sub-meshes. Premium costs $82, paid once and includes Pro functionality alongside listed features such as colorized meshes, texturing, dynamic density and gyroid infill, warp compensation, and curved surfaces. Profiles can be shared, and Project Files can archive print settings. The software supports Windows, macOS, and Linux; downloads are also listed for FreeBSD and Raspberry Pi. Its license permits commercial use and installation on multiple personal computers, with no time or model-size limit, and prohibits reverse engineering.
