Ship Confidently, Roll Back Instantly The Feature Flag Engine separates deployment from release. Ship code to production at any time, then control who sees what with targeting rules, percentage rollouts, and audience segments. If something goes wrong, kill the flag instantly — no redeployment required. Flags are evaluated in real-time at the edge, so targeting decisions never add latency. Boolean, string, number, and JSON flag types cover every use case from simple on/off toggles to complex configuration objects.
