An alternative that others might want to take a look at in this space is Dapr from Microsoft which is language neutral and a CNCF project. Website is dapr.io
Dapr is fantastic if you're using Kubernetes, but we've found people having trouble with the learning curve. Also, Nitric's main SDK right now is for Node.js, but the underlying implementation is in Go and uses gRPC like Dapr. We have other SDKs in the works for Go, Python, Kotlin and C#. There is a bit more detail in the docs https://nitric.io/docs/language-support
