Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- 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.
- Unlimited experiments and seats, so nobody rations testing to save licence cost.
- Serious privacy posture with EU hosting and no data resale.
- Transparent, published pricing.
Limitations
- Post-acquisition roadmap now sits inside Harness's broader platform strategy.
- Requires meaningful event instrumentation before the impact analysis is useful.
- Opaque enterprise pricing.
- Client-side only — no server-side experimentation.
- No feature-flag capability.
- Smaller vendor with a modest ecosystem.
