• 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.

• Local evaluation means no user data leaves your infrastructure — a strong GDPR position.
• Mature, well-documented open-source core with no artificial crippling.
• Kubernetes and Terraform support for infrastructure-as-code 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.

• Experimentation and analytics are thin; it is a flag system first.
• Self-hosting means you own uptime for something in your request path.
• Smaller ecosystem than LaunchDarkly.
