Setup
Installation guide
Choose your platform
Select the appropriate download for your operating system from the download section above. For Windows, the Microsoft Store build is the easiest and keeps itself up to date; otherwise pick Installer or Portable (x64 for most PCs, ARM64 for Windows on ARM devices). For macOS, the universal build covers both Apple Silicon and Intel Macs. For Linux, we recommend installing from Flathub; the AppImage also works on most distributions.
Download the file
Click the download button for your chosen platform. Direct downloads come from our official GitHub releases page — always verify you're downloading from github.com/OrcaSlicer/OrcaSlicer to ensure authenticity and security. Store builds come from the Microsoft Store and Flathub.
