I love SQLiteStudio. On my machine it starts up in < 2s. Version 3.2.1 takes 99MB disk space and is built against QT5. I just ran some queries and the memory usage is only 80MB for a not too large database.
Another self-contained application I like is racket/drracket.
Here's one that doesn't suck:

Maybe that was very complicated to make, all I know is that it's blazing fast and doesn't hog memory. Or hey, take OggDrop and LameDrop, I'm sure there's programs that do the same, are 100 times as big and have 3 options. I don't know if there are 10x programmers, but I know there are 100000x programs, with not one electron app among them.
