There are open source generators for a ton of languages[1]! We've been reasonably happy with their output for ~5 SDKs over the last few years. We did a massive writeup on our experience at the time[2].

In the end...ongoing maintenance there was still enough of a pain that we made the decision to outsource it. For just one or two SDKs I think we probably would have kept going with it, though.
