# Render zshot-cli.com as a PNG on the CPU, without a GPU
zshot --software-rendering https://zshot-cli.com/

Renders on the CPU with SwiftShader instead of the GPU. Use this when no usable GPU is available, such as a host without a graphics device or a user that lacks access to the GPU device nodes. See Linux GPU rendering for how hardware rendering selects the GPU and which device access it requires.
