Secrets Management

AWS Secrets Manager: Pricing, Features & Alternatives

Name: App Stack Builder
Availability: InStock

AWS Secrets Manager stores API keys, database passwords and other secrets encrypted with KMS, controls access through IAM, and rotates credentials on a schedule using Lambda, with ready-made rotation for RDS, Aurora, Redshift and DocumentDB. Secrets can be replicated to other regions, and every access is logged in CloudTrail. It is the default for teams already running on AWS; it is less convenient for local development and for apps outside AWS, where tools like Doppler and Infisical sync secrets more easily.

Pricing is $0.40 per secret per month and $0.05 per 10,000 API calls, so 50 secrets read often by a few services usually cost $20 to $30 a month. New AWS accounts get up to $200 of Free Tier credits that apply to it. AWS Systems Manager Parameter Store is the cheaper sibling for plain config: standard parameters are free, but it has no built-in rotation. As of October 2026.
