CloudFix scans your AWS accounts, identifies cost savings opportunities, and automatically implements fixes around the clock. Unlike tools that just show you where to save, CloudFix does the work — applying AWS-recommended, non-disruptive fixes across EC2, EBS, S3, RDS, Lambda, and more. Fixes...

As answered by people managing LeetCode and CloudFix.
CloudFix's answer:
CloudFix's answer:
Most AWS cost optimization tools show you where to save, CloudFix actually does the saving. It automatically implements AWS-recommended fixes across your accounts, 24/7, without requiring manual intervention. Every fix follows AWS best practices, is non-disruptive, and goes through AWS SSM so you stay in control. Savings compound over time rather than being a one-off result.
CloudFix's answer:
CloudFix is the only platform that combines continuous automated fix execution with full approval control via AWS Change Manager. Tools like ProsperOps, Cloudability, and CloudZero identify savings opportunities but CloudFix implements them. It covers 50+ AWS advisories per week across compute, storage, networking, and database services, and delivers 15–60% savings per AWS service.
CloudFix's answer:
Engineering and FinOps teams at mid-to-large enterprises running significant AWS workloads typically $80K+ in monthly AWS spend. CloudFix suits companies using multiple AWS services who want ongoing cost optimization without dedicating engineering resources to manually track and implement AWS advisories.
CloudFix's answer:
CloudFix was built by the team behind one of AWS's largest customers, managing 120+ SaaS products across thousands of AWS accounts. Keeping costs optimized at that scale without breaking anything was a constant challenge. They built CloudFix internally to automate it, proved it cut costs by 10–20%, and turned it into a product.
CloudFix's answer:
CloudFix is built natively on AWS. It uses AWS CloudFormation for deployment, AWS Cost and Usage Reports (CUR) and CloudWatch Metrics for analysis, and AWS Systems Manager to orchestrate and control fix execution. IAM roles handle secure, read-only cross-account access with no long-term credentials.
