Choose Kryptic over Google Secret Manager when developers need secrets on a laptop, not only GCP resources with Workload Identity.
Google Secret Manager alternativeBest secrets manager (2026)
Kryptic injects secrets through a local daemon. Log in once. After that, npm run dev, dotnet run, and F5 receive secrets over a local socket. The daemon, CLI, SDKs, and encryption engines are open source (GPL-3.0 and Apache-2.0). The server stores ciphertext it cannot open. Machine identities are unlimited and never consume a seat.
github.com/dev-krypticGoogle Secret Manager is the correct store for secrets that GCP services consume through service accounts and Workload Identity. It does not solve the laptop. The unofficial local answer is a file or a downloaded key.
| Kryptic | Google Secret Manager | Why it matters | |
|---|---|---|---|
| Open source | OffersYes. Daemon and CLI are GPL-3.0. Encryption engines and SDKs are Apache-2.0, at github.com/dev-kryptic. The control plane is commercial. | Does notNo. GCP-hosted, closed source. | Anything that can see a secret in plaintext is published. You can verify the blind store without an NDA. |
| Blind store | OffersThe server stores ciphertext only. There is no decrypt path. | Does notGCP can serve plaintext to authorized identities. | A store that can decrypt values server-side can also be breached or compelled into decrypting them. |
| Self-hosting | OffersFull platform on Business and Enterprise. Docker Compose or Helm. | Does notGCP-hosted only. | Cloud is fine until compliance asks where the control plane lives. Then you need a product you can run, not a cluster you invent. |
| Nothing on disk | OffersDecrypted values live in daemon memory for at most five minutes, then inside the running process. | PartialLocal development commonly falls back to exported or synced files. | AI coding agents index the working directory. A .env on disk is one prompt away from a chat log. |
| Kryptic | Google Secret Manager | Why it matters | |
|---|---|---|---|
| Daily workflow | OffersLogin once, then npm run dev, dotnet run, or F5. | Does notGCP SDK, gcloud, or a copied file. | The official GSM path is an API call. The Kryptic path is the debugger you already use. |
| Google SSO | OffersIncluded on Free. | PartialGoogle Cloud Identity is a separate program. | Developers sign in with Google. They do not download a service-account JSON to run the app. |
| Language packages | Offers.NET, Node.js, Python, Java, Go, Ruby, C++, Rust. | PartialGoogle Cloud SDKs for GCP APIs. | The same daemon works if production leaves GCP. |
| Kryptic | Google Secret Manager | Why it matters | |
|---|---|---|---|
| SSO on Free | OffersGoogle, Microsoft, and GitHub on every plan, including Free. | PartialCloud Identity is a separate program. | You should not need an enterprise contract to stop sharing a password manager login. |
| Audit log on Free | OffersImmutable audit log on Free (7-day retention). Values are never logged. | PartialCloud Audit Logs, if you wire them. | An audit trail that waits on an upgrade is a sales page. |
| Machine identities | OffersUnlimited and free. They never consume a developer seat. | Does notPay per secret version and operation. | Every developer is followed by pipelines, previews, and pods. Billing those as seats makes the bill track infrastructure, not people. |
| CI/CD and Kubernetes | OffersMachine identities, CI export, REST API, and a Kubernetes operator on every plan. | PartialAvailable, often with identity or plan limits. | Production delivery should not be a different product from local development. |
