piet VS NanoGUI

You can even check https://github.com/linebender/piet and https://github.com/RazrFalcon/tiny-skia. They are pure rust libraries. Skia as a whole is a big binary to add.

First, at the deepest level, we are moving away from Piet, which is a cross-platform 2D graphics abstraction. Under the hood it uses whatever the standard OS API is. Instead we will be using Vello which we have been building as a research project for years already. It is starting to near its v0.1, which is very exciting. Fundamentally it is a novel GPU accelerated 2D rendering engine with a strong focus on performance. It is not ready for benchmarks yet, but we're confident it will deliver. If you're curious, you can check out the Vello roadmap for 2023.

you can use piet, although that is more of an abstraction over existing, platform-dependent libraries. So not really pure rust, but definitely cross-platform.

Piet is the backend for the Druid UI framework. It is indeed cross-platform. The SVG backend looks like it would work without an OS, but I'm not sure the value of a GUI toolkit without an OS anyway :)

Piet can render text. You can use Piet_common with the BitMapTarget to generate images Here is an example.

Piet (https://github.com/linebender/piet) should work.

So the 3 I'm looking at right now are 1. druid 1. piet 1. bevy

It relies on piet 2D graphic library; on Linux that means GTK/Cairo 2D primitives

NanoGUI

With 2.5 days you probably don't want anything that requires much setup, so Qt is probably a non-starter. You could try this one: https://github.com/wjakob/nanogui, the examples are not the platonic ideal of modern C++ programming, but that also means you don't need much mastery of the language to hammer a program until it has a GUI.

I've dipped my toes into GUI development just enough to know you can have "simple," or you can have "native," but not both. There are smaller projects like nanogui[0] and microgui[1] out there, but of course they're only as small as they are because they don't use native widgets.

### [NanoGUI](https://github.com/wjakob/nanogui)

I have only played with this briefly, but after the initial setup NanoGUI seemed pretty intuitive https://github.com/wjakob/nanogui

There's GTK which is all LGPL (ok to dynamic link to) and things like nanogui which is BSD (just attribution).

Wondering if this was inspired by Wenzel Jakob's nanogui [0] by any chance. (cz that's what I wanted to do, rewrite nanogui in C, so I don't have to rely on a C++ compiler).
