The biggest reason we started working with Stainless was to migrate from the open source generator process we were struggling with, but actually ended up transitioning our hand-rolled Node/JS SDK first because it's both our most popular SDK and because the fragmentation of the JS ecosystem has been a surprisingly big headache[1]. Went into it for reduced maintenance, came out pleasantly surprised at how useful I was finding my own SDK's features around `for...of` on paginated routes, etc.
Congrats on the launch, Stainless crew!
