Google Cloud has announced the public preview of AppLifecycle Manager Feature Flags (ALM FF), a rule-based feature flag service for Google Cloud. It decouples code deployments from feature releases, enabling teams to ship code with features disabled by default and toggle them on safely. Key capabilities include percentage-based traffic rollouts, allowlisting for targeted audiences, dynamic configuration via string-type flags (useful for LLM system prompts), and an instant kill switch for problematic features. The service is built on the OpenFeature standard using the flagd evaluation engine, avoiding vendor lock-in.
