Is there an analog of swagger ui for gRPC API?

Is there an analog of Swagger UI, that can visualise gRPC API (.proto files) to HTML, like Swagger UI for OpenAPI .json or .yaml documents?

Solution

I found protoc-gen-doc. To generate html from .proto files, we can run the following command:

protoc --doc_out=./doc --doc_opt=html,index.html proto/*.proto
