ConfigCat
A commercial flag service with multi-language SDKs, user targeting, percentage rollouts, environments, and audit logs.
Why use it
Small teams use the free tier to disable problems or give testers early access without republishing clients.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
Configuration is third-party hosted and advanced permissions are paid; client SDK values are readable and not a security boundary.
