Standardizing Feature Flagging for Everyone
What's a Feature Flag?
Feature flags are a software development technique that allows teams to enable, disable or change the behavior of certain features or code paths in a product or service, without modifying the source code.
What's 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.
Why standardize?
Standardizing feature flags unifies tools and vendors behind a common interface, avoiding vendor lock-in at the code level. It provides a framework for building extensions and integrations that can be shared across the community.
Open source
