I haven't done anything with javascript in over 6 years, so I can't say which is better.

This comparison might be useful to you. Tauri gives a smaller executable for Windows compared to Neutralino, but slightly larger for Mac and Linux. Also, Tauri's build times are orders of magnitude longer (5 minutes vs 1 second for Neutralino), I'd like some confirmation on your part if that's indeed the case. One thing that really caught my attention, however, is how huge a memory hog Neutralino is on Linux, 700MB for an "empty-app-frameless" project!!

I'm actually curious in trying these two out myself, especially to see if the tauri build times are that bad, and if neutralino's RAM usage is so high on linux.
