Sirr vs AWS Secrets Manager
AWS Secrets Manager is a managed permanent secret store with rotation, tightly integrated into the AWS ecosystem. Sirr is a self-hosted ephemeral credential delivery system built for secrets that should not persist.
When to use AWS Secrets Manager
AWS Secrets Manager is a good fit for AWS-native teams managing long-lived credentials:
- All-in on AWS — If your stack runs entirely on AWS and you need secrets tightly integrated with IAM, Lambda, and RDS.
- RDS credential rotation — Native integration with RDS for automatic database credential rotation, no custom code required.
- Zero infrastructure — Fully managed service. No servers to deploy, no binaries to run.
- Compliance with AWS-backed HSMs — If your compliance framework requires FIPS 140-2 validated HSMs from a specific cloud provider.
When to use Sirr
AWS Secrets Manager has no read-count enforcement, no burn-after-read, and no self-hosting option. Its $0.40/secret/month pricing penalizes ephemeral use cases where secrets are created and destroyed frequently.
- Ephemeral secret sharing — Credentials, API keys, and tokens that should self-destruct after delivery. AWS SM stores secrets forever by default.
- Burn-after-read — Every Sirr secret can be limited by read count, TTL, or both. AWS SM has no read-count enforcement.
- AI agent workflows — Built-in MCP server for just-in-time secret delivery to AI agents. No standing IAM roles, no persistent access.
- Data sovereignty — Self-hosted on your infrastructure, in your jurisdiction. No third-party cloud provider has access to your secrets.
- Predictable pricing — Flat annual plans. No per-secret fees, no per-API-call charges. AWS SM costs compound with volume.
- No vendor lock-in — Sirr runs on any infrastructure. AWS SM locks you into AWS with no export path.

The bottom line
Different problems. Different tools. AWS Secrets Manager is a solid permanent secret store for teams already deep in the AWS ecosystem. But if your use case is sharing credentials that should self-destruct — one-time passwords, onboarding tokens, AI agent credentials — AWS SM is the wrong fit. It stores secrets forever, charges per secret, and locks you into a single cloud. Sirr does one job: secure, ephemeral secret delivery with predictable pricing and zero vendor lock-in.
