miyo

About #

Miyo is a simple web interface I built for two popular image upscalers: Real-ESRGAN-ncnn-vulkan and waifu2x-ncnn-vulkan. Both run locally using Vulkan, and Miyo wraps them in a UI that’s easier to use than the terminal.

I made it mostly for personal use — sometimes I want to upscale old images or anime-style art without uploading them to a third-party service. Miyo makes that process a bit more accessible.

Why I built it #

There are a few GUI wrappers out there, but many of them are heavy or closed-source. I wanted something lightweight, local-first, and a bit more user-friendly. It was also a good excuse to try out Svelte and Fiber (a web framework in Go).

Features #

• Drag-and-drop interface for image upscaling
• Choose between waifu2x and Real-ESRGAN backends
• Docker and systemd support

Notes #

• It works best when run natively (to take full advantage of Vulkan support).
• The Docker version works too, but without GPU acceleration.

Just a small tool I made for myself — but if it helps others, even better.
