Harness Feature Flags
Harness Feature Flags / Split (FME) – Combines flags with real-time metrics-driven automated rollback (e.g., auto-halting a rollout if latency or error rates spike), which is ideal if you want guardrails baked into progressive delivery.
Claude
Split
Harness Feature Management & Experimentation (formerly Split) — Best fit when you are already standardized on Harness or want feature delivery, experimentation, and broader delivery-platform governance under one commercial vendor; otherwise it is usually more platform than a flags-only buyer needs.
