VUEzards
First off LibreScan needs a user-friendly, intuitive and familiar web based frontend. Lowering the entry barrier for blockchain & cryptocurrency users is a key mission of LibreScan, and doing that starts with a UI which is as easy as it gets.
Rule of thumb is that anything that needs a user-manual to be read is not worth using for the consumer!
Choice of framework
The frontend framework of choice is Vue3.
There are various reasons why Vue3 ended up as the winner here as follows:
Masses can read & understand it
If you know HTML + JS + CSS chances are you will have no trouble understanding Vue code. React & Angular are way more intrusive and use much more exotic, custom structuring & syntax.
As with everything related to Blockchain, transparency is key so the more people can comfortably read it, the better.
Flatter learning curve
Again, same rule applies. Vue has a much flatter learning curve compared to React & Angular. We want to allow as many people to contribute as possible, so one plus point for Vue here as well.
Same philosophy
Vue is a truly community driven framework, whereas React & Angular are backed by Facebook & Google respectively. Many developers appreciate tools that are not backed by tech giants, and this is definitely true for the crypto community.
Popularity, market share
Philosophy is nice but when building such an important piece of an ecosystem as LibreScan, one needs to watch out for real-world trends. We did, and Vue is definitely gaining traction:

Sure GitHub stars are not a de-facto measurement, but it clearly projects tendency. The community growth confirms this as well!
