What are the best GUI libraries for a potentially “serious”/large project?

1. dioxus

   1 171 27,641 9.8 Rust

   Fullstack app framework for web, desktop, mobile, and more.

   

   If you're happy floating on web technologies and using SVG to render graphs (or shipping some wasm locally and using webgl/canvas) then you might enjoy my project https://github.com/DioxusLabs/dioxus . It's still pretty young but we're moving quickly and rapidly building new features as people build out their apps.

2. InfluxDB

   www.influxdata.com featured

   InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.

   

3. fltk-rs

   2 31 1,724 9.0 Rust

   Rust bindings for the FLTK GUI library.

   

   Besides GTK I can recommend FLTK. It has been around for a long time and is very stable.

4. Slint

   3 60 3,094 9.9 Rust, C++, JavaScript

   Discontinued Slint is a toolkit to efficiently develop fluid graphical user interfaces for any display: embedded devices and desktop applications. We support multiple programming languages, such as Rust, C++ or JavaScript. [Moved to: https://github.com/slint-ui/slint]

   

   The most promising GUI hasn't been posted here, SixtyFPS. It's in it's early stages and not FOSS, but it's built by some ex-QT cats and has a lot of potential.
