GO Feature Flag is a completely open-source, simple and lightweight feature flag solution. The solution has been built for application of feature flags in your code without the need of any vendor. **GO Feature Flag** was initially developed for the GO language, but with the new standardisation of feature flags by [Openfeature](https://openfeature.dev/) project, it now supports multiple languages *(`JAVA`, `typescript`, `javascript`, ...)* with a simple server to host.
