O SOPS criptografa arquivos de secrets arbitrários com KMS/age/PGP; o Sealed Secrets é um controller do Kubernetes que descriptografa CRDs SealedSecret em Secrets dentro do cluster.

O SOPS é de uso geral: ele criptografa qualquer arquivo estruturado e se integra a muitos backends e ferramentas de CI, descriptografando onde quer que você tenha a chave. O Sealed Secrets é específico do Kubernetes: você criptografa com uma chave pública do cluster em um SealedSecret que só o controller dentro do cluster consegue descriptografar, mantendo o plaintext totalmente fora do Git. O SOPS vence em flexibilidade entre ambientes; o Sealed Secrets vence em um modelo GitOps enxuto e nativo do Kubernetes.

## Comparison

|  | SOPS | Sealed Secrets |
| --- | --- | --- |
| Escopo | Qualquer arquivo | CRDs do Kubernetes |
| Descriptografia | Em qualquer lugar com a chave | Controller dentro do cluster |
| Backends | KMS, age, PGP | Par de chaves do cluster |
| Adequação a GitOps | Ampla | Nativa do K8s |
| Melhor para | Secrets entre ambientes | Secrets GitOps do K8s |

## Caso de uso e escopo

O SOPS serve a times que gerenciam secrets entre muitos ambientes e tipos de arquivo com backends de chave flexíveis. O Sealed Secrets serve a GitOps exclusivo do Kubernetes onde você quer manifests criptografados no Git que só o cluster de destino consegue fazer unseal.

## Adequação a ops e CI

O SOPS descriptografa no CI ou no deploy com uma chave; o Sealed Secrets depende de um controller dentro do cluster, então o CI só precisa da chave pública para criptografar. Runners gerenciados mais rápidos encurtam as etapas de criptografia/descriptografia e de build de manifests em qualquer um dos fluxos.

## Decide with your own numbers, not a feature table

Feature comparisons age badly and rarely decide anything, because both tools in a mature category can do the job. What differs is how each behaves on your repository, and that takes one afternoon to measure.

```Terminal
# time a cold install with each candidate, cache cleared
hyperfine --prepare "rm -rf node_modules" --warmup 1 \
  "<tool-a> install" "<tool-b> install"

# and the thing CI actually pays for: a cold run with no local cache
docker run --rm -v "$(pwd):/w" -w /w node:22 sh -c "<tool> install"
```

> Measure the cold path. Warm local benchmarks favour whichever tool you already have cached, which is exactly the condition a CI runner never has.

## What actually changes when you switch

- Lockfile format. A switch is a one-way door for anyone still on the old tool until everyone migrates, so plan it as a single coordinated change.
- Resolution strictness. Tools differ on whether an undeclared transitive import works, and the stricter one will surface latent bugs as new failures.
- CI cache configuration. The cache path and key differ per tool; carrying over the old ones silently disables caching.
- Everyone on the team and every runner must move together. Pin the version so they cannot drift.

## O veredito

Quer arquivos de secrets criptografados flexíveis e entre ambientes: SOPS. Quer selagem nativa do Kubernetes onde só o cluster consegue descriptografar: Sealed Secrets. A amplitude favorece o SOPS; o GitOps nativo do K8s favorece o Sealed Secrets.

## FAQ

### SOPS vs Sealed Secrets: Which GitOps Secrets?

SOPS is general-purpose: it encrypts any structured file and integrates with many backends and CI tools, decrypting wherever you have the key. Sealed Secrets is Kubernetes-specific: you encrypt with a cluster public key into a SealedSecret that only the in-cluster controller can decrypt, keeping plaintext out of Git entirely.

### Use case and scope?

SOPS suits teams managing secrets across many environments and file types with flexible key backends. Sealed Secrets suits Kubernetes-only GitOps where you want encrypted manifests in Git that only the target cluster can unseal.

### Ops and CI fit?

SOPS decrypts in CI or at deploy with a key; Sealed Secrets relies on an in-cluster controller, so CI only needs the public key to encrypt. Faster managed runners shorten encryption/decryption and manifest-build steps in either flow.

### Which should I choose?

Want flexible, cross-environment encrypted secret files: SOPS. Want Kubernetes-native sealing where only the cluster can decrypt: Sealed Secrets. Breadth favors SOPS; K8s-native GitOps favors Sealed Secrets.
