CST VerdictBased on our analysis of available product data, here is our conclusion:
Platform engineering teams managing multi-cloud infrastructure at scale will get the most from Cloud Custodian because its YAML-based policy engine lets you write once and enforce across AWS, Azure, and GCP simultaneously, something most CSPM tools force you to configure separately. 5,794 GitHub stars and active community contributions mean you're inheriting battle-tested policies rather than starting from scratch. Not the right fit if you need point-and-click policy management or expect vendor support; Cloud Custodian demands engineering resources to deploy and maintain, and you're responsible for the policy logic.
DevOps-first security teams who want to codify cloud compliance without vendor lock-in should start with Selefra; its SQL-based policy engine lets you write once and run across AWS, Azure, GCP, and 20+ SaaS platforms without relearning a proprietary language. The open-source model with 542 GitHub stars means you're not paying per account or per cloud, and GPT integration actually works for converting compliance frameworks into executable policies rather than serving as marketing theater. Skip this if your org needs managed services, pre-built industry benchmarks out of the box, or remediation automation; Selefra assumes you'll build policies and handle response workflows yourself.
