• Extremely reliable flag delivery with offline fallbacks — this is infrastructure you can trust in the request path.
• Best-in-class governance: approval workflows, audit logs, role-based access.
• Code references and stale-flag detection actually help you remove dead flags.

• 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.

• The most expensive option in the category by a distance.
• Experimentation is competent but less sophisticated than dedicated statistics platforms.
• No meaningful free tier for evaluation.

• 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.

Engineering organisations where flags are critical infrastructure and governance is required.

Privacy-sensitive or cost-sensitive teams that want flags without sending user data to a vendor.
