I wanted to ask what the preferred tool, method or framework is when using feature flags with Flask applications. The main problem is that the most relevant result has not seen an update since 3 years, there is only one non-free feature flag as a service, and the alternative to roll it myself with Environment variables or something with injecting values in the request header without Nginx. For context, it is a relatively small application that is containerized and has an automatic Nginx reverse proxy.
Therefore, the question is what is the defacto method for implementing feature flags in Flask apps?
