SOPS vs AWS Secrets Manager
Both are alternatives to HashiCorp Vault. Here's how they stack up — verified facts, no spin.
Also searched as AWS Secrets Manager vs SOPS — same comparison, one verdict.
SOPS
Encrypt secrets into the repo. No server to run at all.
SOPS takes the opposite approach: rather than a service that hands out secrets, it encrypts the values inside YAML, JSON or ENV files so the file itself is safe to commit, with keys held in AWS KMS, GCP KMS, Azure Key Vault, age or PGP. Structure stays readable, values are ciphertext, and diffs still work. There is no server, no high availability to design, and nothing to page anyone about at 3am. Originally Mozilla's, now a CNCF project under MPL-2.0 with about 22.6k stars. It is the right answer far more often than its simplicity suggests — and the wrong one the moment you need rotation, revocation or an audit trail.
AWS Secrets Manager
The obvious answer if everything already runs in AWS.
If your workloads are on AWS, Secrets Manager is already available, already inside your IAM boundary, and already covered by your compliance paperwork. It does rotation with Lambda, integrates natively with RDS, ECS and EKS, and requires no new infrastructure of any kind. It is priced per secret per month plus API calls, which is cheap for dozens of secrets and less cheap for thousands. The obvious limitation is the obvious one: it is AWS-only, so a multi-cloud estate ends up running something else alongside it, which defeats the point of a central secrets store.

| Open source | Yes | No |
| Self-hostable | Yes | No |
| Local-first | Yes | No |
| License | MPL-2.0 | Proprietary (hosted service) |
| Pricing | Free and open source. No server, so no hosting cost either. | Roughly $0.40 per secret per month plus a small per-10,000-API-call charge. Rates checked 2026-07-31. |
SOPS edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
SOPS
Strengths
- +No service to run, scale, back up or monitor — the operational cost is zero
- +Secrets live in Git with real diffs and full history
- +CNCF-governed under MPL-2.0
- +Works with cloud KMS, age or PGP for key custody
Trade-offs
- −No dynamic secrets, no automatic rotation, no revocation
- −Audit trail is your Git history and your KMS logs, nothing more
- −Rotating a leaked secret means a commit and a redeploy
- −Not a fit for large teams needing fine-grained runtime access control
AWS Secrets Manager
Strengths
- +Already inside your existing IAM, VPC and compliance envelope
- +Native rotation with RDS, Redshift and DocumentDB
- +Zero infrastructure to run or patch
- +Cheap at small secret counts
Trade-offs
- −AWS-only — useless as a central store in a multi-cloud estate
- −Per-secret pricing adds up quickly at scale
- −Far less capable than Vault for dynamic credentials and PKI
- −Deepens AWS lock-in rather than reducing it
