• Automatic metric impact on every flag catches regressions nobody thought to measure.
• Guardrail alerts stop a bad rollout before it reaches everyone.
• Strong data-platform integrations.

• Statistically rigorous — sequential testing, CUPED and diagnostics are core, not add-ons.
• Metrics defined once in the warehouse and reused across every experiment.
• dbt integration fits existing analytics engineering workflows.

• Post-acquisition roadmap now sits inside Harness's broader platform strategy.
• Requires meaningful event instrumentation before the impact analysis is useful.
• Opaque enterprise pricing.

• Requires a warehouse and a data team; not usable by a product manager alone.
• Feature-flagging capability is lighter than dedicated flag platforms.
• Now part of Datadog, which changes the strategic picture.

Teams that want every release measured, not just deliberate experiments.

Data-mature organisations where experiment results must withstand scrutiny.
