This is a non safe for work, as in lewd, instance.
It’s safe to assume that anything you see here will be lewd.
Just letting you know. If you view the content and then pull a surprised pikachu when you see big anime tiddies, Judy Hopps getting railed or some furry vore… Then it’s on you.
Should this popup continue to show up, you may want to enable cookies or disable privacy focused addons on your browser, I assure you we won’t track our user.
Should that fail, some users claim they got rid of it by hammering the ok button.
Good separation between business logic and UI without effort, cross-platform UI in any language, possibility to turn it into a web-accessible service in the future, great choice of UI frameworks and battle-tested components if you decide to go for a web framework and language.
As an example of a successful software that followed this approach: Synchthing. All versions run a local web service in the background. The Desktop version just opens a browser on the index page. The Android version is a native app that calls the exposed REST API on localhost, bypassing the web UI.
As an example of a much more complex software, albeit not FOSS: EasyEDA. It’s a web software, but it also comes as a desktop app (which I never tried) which I assume is not much more than a frame for the web view.
My recommendation: write the UI with React on Vite in TypeScript, and write the business logic in your general purpose language of choice (mine would usually be C#).
