This is an old article but it explains Foundryside better than I could. It’s a fairly standard fantasy setting with its own unique form of magic, and yet the story includes multiple cyberpunk tropes.
The article was written before the rest of the trilogy was released. I’ve read the trilogy and unfortunately, I’d only consider the first book to be cyberpunk. The series goes pretty far off the deep end to the point that the third book is about (I’m trying to use spoiler tags here):

two hive-minds battling for control of humanity. All the protagonists are part of one hive-mind and are trying to stop the evil hive-mind. The two hive-minds aren’t even present in book 2 so this was a pretty drastic departure from the rest of the series.
I’ve read two of them (got them when a friend cleaned out their bookshelf) and loved them. 100% cyberpunk themes and structures in a fantasy Age of Sail setting where the magic is basically using snippets of code to hack reality. And that setting is a pretty good fit tbh - as far as I know, IRL modern megacorporations still haven’t attained the scope and power the British and Dutch East India companies had in their prime. And it was a very deliberate writing choice to have the illegal human experimentation taking place away from the corporate strongholds in the city, far out on a distant slave plantation. The first book especially is rad and though I wouldn’t have thought to bring it up here, I’d definitely recommend it.
