i found one on fdroid but it was old and the directory selector was broken and couldn’t really work outside of it’s default for some reason, it also rendered the page i’m trying to use really weirdly, like it wasn’t sending some file over and the css got borked.
Found one that wasn’t foss, installed it, opened it, “buy premium to unlock this feature”, uninstalled it.
I use SimpleHttp server but it’s not open source and available only on play store. I use this to download epub from my e-reader after having downloaded them on my phone. Now I will look into foss solutions proposed in this Post, through termux or other apps, thanks.
Edit: indeed with termux + caddy + termux widget it’s just perfect
