Forest-ttk-theme VS nicegui

and for a quick overview of other GUI solutions: https://lispcookbook.github.io/cl-cookbook/gui.html (Gtk4, Qt4 and 5, LispWorks' CAPI (incl. for mobile runtimes), IUP…)

I have been pleasantly surprised lately to discover surprisingly nice-looking Tk themes (like https://github.com/rdbende/Forest-ttk-theme). We can use them from CL too, with the nodgui library :) (see link)

For the web, CL & HTMX work well too.

Styling is hard(ish) - compared with CSS, or XAML, it is relatively difficult to style. What seems to work best are using the pre-built themes e.g. forest-dark/forest-light.(https://github.com/rdbende/Forest-ttk-theme) Even with the advent of ttk, there is no common way to style elements. As far as I could tell, this theme e.g. used pngs, there was no way to override individual style elements without actually modifying the underlying style. Ttk styles do help a lot, (I managed a half-way decent pastel-color theme, the issue was with more nitpicky styling management, there are no good defaults), but they are not enough.

I was looking at this space and nicegui seemed like the best ootb experience.

Dash is similar in spirit, as a "build web UIs with Python" framework. Dash seems more similar to nicegui (https://nicegui.io) architecturally than to Hyperdiv. Like nicegui, it builds a static dom that is then mutated via callbacks or data bindings.

By contrast, Hyperdiv lays out UI declaratively based on state, and when state changes, the app re-runs, generating an updated UI. Streamlit and Hyperdiv seem to work similarly, though I'm not sure how Streamlit handles state and state-based layout.

For native GUI, DearPyGui[0] as modern as you can.

For browser web-based GUI, you can use nicegui[1]

I want to bring to attention a set of frameworks that make webdevelopment using Python simple and fun. The popular opinion maybe that webpages developed with Python maybe slow. But this is not the case. Do checkout https://github.com/ofjustpy/ofjustpy/, https://github.com/zauberzeug/nicegui/ and https://github.com/justpy-org/justpy . All these frameworks are build on top of Starlette and make web development really easy. If you want simple and ready to use the nicegui is the choice. If you want fast, scalable, and more control then give ofjustpy a try.

Yes, NiceGUI aims for a very gentle learning curve. Coming from Streamlit I suspect your main adaptation will be that in NiceGUI you need to write valid Python code. Streamlit constantly reevaluates your script which feels nice and easy but creates lots of problems down the road. See https://github.com/zauberzeug/nicegui/discussions/21.

Auth is a big limitation. It's not a built-in component, they have [an example](https://github.com/zauberzeug/nicegui/blob/main/examples/aut...) using the FastAPI layer for auth, but I haven't had time the time to try implementing it. It's definitely not something you get out of the box with NiceGUI.

For scaling, I am viewing it mostly as an internal tool builder. I wouldn't recommend it for external applications. So as far as scaling an internal app I think it works fine. [Their website](https://nicegui.io) is built with NiceGUI, and it works fine, but you can feel the lag occasionally on some of their larger demo pages.

Well, I was at PyCon Ireland last weekend and I missed the NiceGUI talk. I hear postive things about it and anything shiney and anything frontend-related always catches my attention (although I admit talking to a friend when I missed this talk was just as fun, and it was worth it).
