Hi, We have been working on APIVault, which is an API Gateway that supports MySQL, PostgreSQL and Microsoft SQL Server.
Written fully in Go (not just some NGINX proxy like Kong), we have a "protect" mode which defends OTP/SMS endpoints against DoS attacks (which can drain a company's SMS credits)
Kubernetes Ingress support is in the works.
