I've tried to play around with Turbo[0] from the Hotwired project, and've always struggled to get off the ground with it. Whenever I've gone to do anything with it, the documentation has always seemed lacking, and it seemed like their stance was mainly "just use our Ruby Gem!", which isn't so appealing as a Go dev.
Yeah I can see how Turbo is more geared towards Rails. I feel like Stimulus is easier to combine with non Rails backends. I found this starter project for Stimulus and Go, if you're interested: https://github.com/narup/go-stimulus
