At the start of Rookout, we used to have a giant Python monolith and it started being hard to maintain - we realized that using Kubernetes, it would be easy enough to have multiple micro-services each responsible for their own tasks.

After almost a year of micro-services, we are slowly slimming it down to a Golang backend with a NodeJS GraphQL facade for easier frontend development.

NodeJS has the most popular and better options for GraphQL, and it is for a reason.

Between having protobuf schemas between our services, a GraphQL schema to manage our queries, and a very durable backend in Golang, we are able to do anything we want and handle large scale very easily.
