Since NGINX Amplify was discontinued on January 31, 2026, you might be interested in GetPageSpeed Amplify - a drop-in replacement that:

• Works with the existing nginx-amplify-agent
• Includes Gixy security checks (static NGINX config security analysis - something the original Amplify never had!)
• Has a free tier for personal/small deployments

Just update your agent config to point to the new API endpoint:
