Hey there! So, kinda of, we definitely took inspiration from RunKit and in the future we want to support different languages. Our main goal right now is to focus on the core developer experience, illustrating how one can use a company's API with a real use case, instead of trying out a single independent API endpoint. Once, we nail that, we would like to move to new languages.

I took a quick look at your podcast API product. First, this seems awesome! Would love to try it. Second, would love to see a web example consuming your API (if you don't have one). Maybe that's something that you could use SideGuide for and would be more aligned with our current state. Although I totally see why it would be awesome to execute all the api endpoints in different languages. Will keep that in mind and maybe explore that in the future.
