Add SBproxy to the API Gateway section.

Hi,

Thank you for your contribution.
The project seems to be very young, right?

I recently decided to open source it. I'm working on adding some more documentation to help people transition from existing gateways. I'm bullish on this project given Trafaek and Bifrost are the only other projects that do something similar using Golang. I'm adding a few more features to make it on parity for load balancing, but for routing/WAF I am confident this project offers a great solution for indy developers.

And to answer a common question - no this isn't a vibe-code project. While I do leverage agentic development the engine and routing was developed over 4 years ago!
