Api-umbrella , open source and does the job for me. Nicely configurable, only thing for me is that it doesn't run on arm hardware.
Uses NGINX and others. I use it for a graphql backend and some reverse proxying to specific webhook microservices.
Thanks for the info. I haven't heard about api-umbrella. Just visit the site and the documentation and I think I like what I see, small, easy to read and straight to the point. I will try to play with that some days.
