Question inspired by How to persuade developers to start using feature flag toggles?
- Find a feature toggle framework. Management/the business may be more amenable to trying something supported by a common system
and this comment on it:
+1 for the framework bit. I've seen too many people roll their own feature toggles and it's always nasty, nasty code. – Jduv 4 hours ago
So which are those feature toggle frameworks?
Pointers to the official framework sites are mandatory, but also at least some quotes from the site with a short description and maybe a summary of its features to not make them link-only answers.
Comments about the personal experiences in using the frameworks are welcome.
