Check the "Domain Rating" of Flet on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of Flet's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of Flet on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

> a locked down GUI that is efficient to use and designed to display the data that the commandline tools produce [...] You can have all that. There are various data presentation tools out there (one I can think of right now is Streamlit as I tried it out a few months ago, but I'm not really a data person, Python is just my primary language).

It's more the latter, particularly when Rust is used in libraries (eg. FastAPI) as opposed to tools, as it's destroying portability. For example I use flet[0] in some of my projects, and I have to be increasingly careful about the other dependencies as there is no support for the Rust toolchain within Dart/Flutter, and even if there was it still sounds like it'd be a nightmare to maintain. Same applies to any... - Source: Hacker News / over 1 year ago

The problem with all this combining is that it's making apps less portable. Like I want to make apps that work on desktop+mobile with flet[0], but now I have to specifically seek out more "traditional" alternate packages and hope they stayed in reasonable feature parity with these Rustified Frankensteins.

Flet (https://flet.dev) might be easier for backend devs as it doesn't assume any web experience at all. You use controls (aka widgets) with events (not request/response) and can build not only web, but desktop and mobile apps - all with a single codebase.

When developing or selecting an MRZ (Machine Readable Zone) recognition SDK, the primary challenge lies in finding an appropriate dataset for testing. Acquiring genuine MRZ images is challenging, and due to privacy concerns, they aren't publicly accessible. Therefore, crafting MRZ images becomes a practical solution. Fortunately, there's an open-source Python MRZ generator project, available for download from... - Source: dev.to / almost 3 years ago

Web and Flutter support for other languages is debatable to be fair: you have webassembly so if your language of choice supports it as a compilation target you should be good, sure it doesn't count as a toolkit, but Blazor is a real example that relies on that, although you will need JS anyway to act on the DOM; Flutter has Flet that allows you to use it through Python and also other languages are coming if I'm...
