Kolibri - A GUI framework made to be as lightweight as its namesake

What is Kolibri?

Kolibri is an embedded Immediate Mode GUI mini-framework very strongly inspired by egui.

Current State

Kolibri is currently in a very early stage of development. It is not yet ready for use in any non-experimental projects. If you're interested in contributing, feel free to open an issue or a pull request.

You can also generally find me in the embedded graphics matrix channel if you have any questions.

Sidenote: What is a Kolibri?

Kolibri is the german word for Hummingbird, which is a small bird that is very fast and agile. There is also an OS with a similar name (KolibriOS), for similar reasons: It is small and fast. This library is in no way associated with the KolibriOS project, but I do encourage you to check it out if you're interested.

Why another GUI framework?

Actually, it's in some ways the first, at least in its very, very specific niche. The embedded-graphics environment is awesome, although fairly low-level. The goal of this library is to make creating simple to somewhat-complex GUIs trivially easy. There is nothing that does this, really, at least at the time of writing this library.

What is this not?

Kolibri is not a high-end GUI framework. It is not meant to be used for creating very complicated or super nice-looking user interfaces. If that's something you're interested in, check out the rust bindings for lvgl or slint (not free for commercial use).
