For my use case, this would have to be incredibly awesome for it to justify self-hosting such a complex and critical system. My current go-to solutions are AWS API Gateway, Azure API Manager and Apigee.
I share your concern about managing solutions. I only know AWS API gateway but I can tell you the features it offers are very limited compare to Foss solutions
Indeed Many members in the Slack channel reported that they came to APISIX because its feature-rich, check its README, please: https://github.com/apache/apisix
