• macOS: one universal build for Apple silicon and Intel.
• Linux: x86_64 and aarch64 as AppImage, Flatpak, .deb, .rpm or tarball, and RISC-V as .deb, .rpm or tarball.
• Web: a static site you host yourself (litho-web-<version>.zip). It runs on WebGPU and falls back to WebGL2. The web build has no control channel, and Save and Export download the file.

All files are on the latest release. See Install Litho for steps.
