I just discovered that there is a standard for feature flags called OpenFeature. It is actually an incubating project under the CNCF!

Having a common API to call different vendors (no vendor lock-in!) is awesome!

There is SDK available for multiple languages (including Java - example on screenshot from the docs).

Also multiple 'providers' - translation layers to use the same OpenFeature API with the different flag management system providers

And the link https://openfeature.dev ๐Ÿ”—
OpenFeature

OpenFeature is an open specification that provides a vendor-agnostic, community-driven API for feature flagging that works with your favorite feature flag management tool or in-house solution.
