CST VerdictBased on our analysis of available product data, here is our conclusion:
Developers and security teams managing multiple AWS accounts locally should reach for AWS Vault first; it's the only free tool that keeps IAM credentials out of plaintext config files by leveraging your OS keystore, eliminating the most common path to credential exposure in development environments. With 8,960 GitHub stars and active maintenance, it's proven reliable enough that most AWS-native shops have already standardized on it. Skip this if your team doesn't use local development workflows or needs centralized credential rotation and audit logging; AWS Vault is a developer tool, not a secrets manager for applications in production.
Developers managing secrets across multiple cloud providers during local development should use Teller for its provider-agnostic approach; it pulls from AWS Secrets Manager, HashiCorp Vault, 1Password, and others without forcing a single vault standard. The 3,181 GitHub stars and free pricing mean adoption friction is genuinely low for teams testing secret rotation workflows before committing to a paid platform. Skip this if you need runtime secret injection in production containers or centralized audit logging; Teller is built for the laptop-to-staging workflow, not the control plane.
