What popular crates are available to build GUIs with widgets WITHOUT GPU? - eviltoast

For some reason, it seems popular for GUI crates to use the GPU. I just want to make simple widgets, for like a calculator.

No fancy graphics. I want it quite lightweight.

For some reason, popular GUI crates love to do everything through a GPU, which bumps up the memory / cpu use significantly.

    Slint fits the bill: We have a demo running on a line-buffer in a microcontroller with <300KiB of RAM. Framebuffers are of course supported as well, as is GPU-accelerated rendering.

    Funny you should mention that. I think iced as of four days ago can do this!

    If I’m reading the release notes and Cargo.toml right, cargo add iced --no-default-features and you should be good to go, as tiny-skia will be used as a rendering backend instead of wgpu.
