Sundy Calendar is a new project, early in development. I was searching for the "right" stack for a true cross-platform application.

I use a Mac, an iPhone, and a Windows computer in my day-to-day life and work. I occasionally use Linux, and can see myself using it more in the future to replace my Windows setup.

The goal was to build a full working application in Avalonia initially. Then I figured, why not try Uno too? Or see how other platforms feel? The real motivation is to experiment and see how things are done differently across stacks. Which feels better? Which "clicks" with me more? The last time I did true cross-platform development was with Expo, which had a fantastic dev experience.

Before starting with Uno, I tinkered with Flutter, mostly having an LLM generate a barebones calendar app to walk through the tooling. Reading through the Flutter code, I realized I wanted to stick with C#. From there, I built with Avalonia and Uno in parallel while also testing a Swift application.

After a few weeks, I realized Tauri — initially excluded from my choices — did support iOS/Android (the reason I hadn't tried it earlier). I gave it a shot, and boom: Blazor. It's no secret I enjoy working with Blazor, so it's no surprise I'm enjoying the Tauri experience.

Conclusion? None yet. Below are my current thoughts and status. Next step is to analyze this more, flesh out the Tauri-Blazor solution, and decide which stack to move forward with.
