Yes. OpenTofu is a drop-in replacement for Terraform, supporting the same HCL syntax, providers, and state format. Migration requires minimal changes.
AWS does not offer a public API for the full Pricing Calculator. Browser automation via Playwright is currently the only way to programmatically generate accurate, shareable estimates across all 159 services.
No. It focuses on cost estimation from IaC, not runtime configuration drift. Drift detection for ElastiCache replication groups requires dedicated tooling or custom scripts.
