StackSage is a privacy-first AWS audit solution designed to run inside your GitHub Actions environment. It provides comprehensive insights into your cloud infrastructure, focusing on cost savings, security guardrails, and overall security posture. The tool generates a detailed audit pack that includes a human-readable summary, an HTML report, and machine-readable JSON/CSV artifacts, enabling teams to easily review and act on findings.

Key features include:

Cost optimization insights such as idle EC2 instances, EBS volume over-provisioning, and RDS signals
Security posture assessments covering IAM hygiene, exposure signals, encryption, and audit logging
Network waste detection including unused NAT gateways, EIPs, and load balancers
Customizable report filtering and resource exclusions via configuration files

It operates entirely within your GitHub Actions runner, utilizing a customer-controlled read-only IAM role to ensure data privacy and security. The workflow outputs include a summary, an HTML report, and JSON/CSV findings, suitable for automation, dashboards, or internal review. The platform is ideal for teams seeking continuous cloud cost management, security compliance, and infrastructure visibility without sharing AWS credentials.

Pricing options include a free self-serve trial with limited features and a paid plan at $99/month offering deeper coverage, richer evidence, and recurring runs for ongoing monitoring.
