EEZ Studio

Pros: EEZ Flow code generation, now supports themes. Easy to use. Open Source and fixes happen fast. Supports LVGL. There is a lot of pros!

Cons: Documentation is not great but developers are very supportive on discord. Its a early in development but maturing fast. You might encounter bugs in software.

Overall: If your using Squareline Studio, seriously you may want to change to this. Its way better in so many ways.

Pros: Very slick, responsive and easy to understand UI. The "Flow" block-style programming is some of the best I've seen. Generating object lists from arrays, keypress event actions and the ease of applying conditional styles make it much more suitable for non-touchscreen GUIs than most other solutions.

Cons: Still in early development so some flaws are excusable, but I'd like to see compilation of standalone apps expanded on (for example no borders/title bar option) and included within the main Studio application.

Overall: Very impressive, especially for how early in development things are. I've tried other low-code GUI builders like AppGyver and Squareline and this beats them both.

Pros: - UI is very similar to SquareLine Studio, so very little ramp-up time needed to learn EEZ Studio if one is already familiar with sq studio. I used only the lvgl project.
- multiple windows can be opened
- lvgl v9 support
- c code generator is customisable to some extent
- user widgets
- support via discord server is very responsive and helpful
- very stable! I didn't had any crashes, except it gets slow/unresponsive when using the color picker for a longer time
- open source and free
- active development

Cons: - tabview widget is missing
- no localisation support for lvgl
- the run/debug mode is not wysiwyg in all cases especially when trying out different image formats with alpha channels. The compiled result looked different.

Overall: Excellent tool for lvgl design and code generation for all types of micro processors. Under active development and very responsive support.

Pros: - Very easy to use! It's a drag and drop interface.
- Helps you create LVGL interfaces with ease, even allowing you to share styles between components.
- Logic flows are very easy out of the box.
- Native coding lets you expand well beyond what EEZ Studio offers and allows you to introduce custom code.

Cons: - I wish native coding was a bit cleaner/easier: Currently the only way to share data between the EEZ UI code and your native code is to do so through global variables. This isn't bad but I wish there was a way to create getter functions to read local variables too.

Overall: I wouldn't have been able to get so far in development without this library. This project is actively under development but I feel like it will surpass Squareline with a little more time and love!

Pros: -The intuitive, no-code interface enabled me to create pretty advanced projects I would never have tacked otherwise
-Very responsive and helpful from the devs, always willing to chime in with tips to achieve specific goals
-Fast paced development, having experienced issue reports fixed within the day

Cons: -It remains a fairly specialized software; you might not need to know exactly how to write code, but some good general foundations in computing remain a must to enjoy its full potential

Overall: Overall absolutely pleased with the whole experience Envox has offered.
It is a software designed by folks that use it for themselves, with a lot of quality of life features making it a lot less daunting to use.

I've been using it mostly to develop automated test protocols for my electronics products, using the SCPI communication features letting it interface with my measuring instruments.

I can't recall how many times I've asked if it was possible to do this or that, only to find out that yes, this was already thought in and there's already a simple solution baked in.

Massive props to the Envox team for making development and automation more approachable. Thank you!
