LaunchDarkly vs. Harness

LaunchDarkly helps teams ship faster, learn continuously, and control features in real time all from one unified platform. Harness adds basic flagging to CI/CD, but lacks deep targeting, auto-rollbacks, and built-in experimentation — slowing teams down and potentially increasing release risk.
