ConfigCat
A commercial flag service with multi-language SDKs, user targeting, percentage rollouts, environments, and audit logs.
Why it’s here
Small teams use the free tier to disable problems or give testers early access without republishing clients.
Best fit
Analytics, feedback, support, and updates keep a released game healthy over time.
Before you commit
Configuration is third-party hosted and advanced permissions are paid; client SDK values are readable and not a security boundary.
