The interesting thing is how a lot of the focus in these comments has been around optimizing and A/B testing but feature flags have value in being able to continuously integrate and deploy without disrupting your production environment. For teams that want to merge and release regularly and have launches be easy I think LaunchDarkly is a big win. With that said, you can do it yourself. For example here is my elixir/redis feature toggle library https://github.com/securingsincity/molasses https://github.com/securingsincity/molasses and a feature toggle library in PHP that I've used and contribute to https://github.com/opensoft/rollout https://github.com/opensoft/rollout
