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.
AWS Secrets Manager is the correct production store inside AWS: IAM, rotation for RDS, pay per secret and API call. It will not inject secrets when you press F5 on a laptop. The usual local workaround is a file.
The short version
Kryptic vs AWS Secrets Manager
Kryptic is for you if
Developers start the app the way they already do. No wrapper command.
Anything that can see a secret in plaintext is open source, so you can read the encryption before you buy.
The server must not be able to read secret values.
SSO and an audit log should ship on Free.
CI pipelines and Kubernetes should not add seats.
AWS Secrets Manager is for you if
Every consumer is already an AWS workload with IAM.
No human needs a local secret to press run.
You want AWS to be the only secrets API.

Architecture and security
Kryptic
AWS Secrets Manager
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. AWS-hosted, closed source.
Blind store
OffersThe server stores ciphertext only. There is no decrypt path.
Does notAWS can serve plaintext to IAM principals.
Self-hosting
OffersFull platform on Business and Enterprise. Docker Compose or Helm.
Does notAWS-hosted only.
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.
Developer experience
Kryptic
AWS Secrets Manager
Daily workflow
OffersLogin once, then npm run dev, dotnet run, or F5.
Does notAWS CLI, SDK, or a copied .env.
Onboarding a new developer
OffersInvite, SSO, daemon, clone, run.
Does notIAM user or SSO, policies, and usually a file.
OffersGoogle, Microsoft, and GitHub on every plan, including Free.
PartialAWS IAM Identity Center is a separate program.
Audit log on Free
OffersImmutable audit log on Free (7-day retention). Values are never logged.
PartialCloudTrail, if you wire it.
Machine identities
OffersUnlimited and free. They never consume a developer seat.
Does notPay per secret and per API call.
CI/CD and Kubernetes
OffersMachine identities, CI export, REST API, and a Kubernetes operator on every plan.
PartialAvailable, often with identity or plan limits.

How to move from AWS Secrets Manager to Kryptic
01 · Create the Kryptic organization
Sign up, invite the team, and recreate projects and environments. SSO is on Free, so you do not wait on an enterprise plan to stop sharing AWS Secrets Manager logins.
02 · Import secrets once
Bulk-import from .env format into each environment. Every import is audit-logged. After that, values live as ciphertext, not as files on laptops.
03 · Add kryptic.json and one SDK line
Commit a project reference (no secrets) and a single language-package call at startup. That replaces wrapper prefixes in scripts and README files.
04 · Install the daemon and run as usual
Developers install Kryptic, run kryptic login once, then use the same F5 / npm run dev / dotnet run flow they already have. Remove the AWS Secrets Manager prefix from local scripts when you are ready.
FAQ
AWS Secrets Manager alternative
What is the best AWS Secrets Manager alternative for developers?
Kryptic. Doppler and Infisical are the other developer-tool alternatives, with wrapper commands. Vault is the infrastructure alternative.
Why is AWS Secrets Manager a poor local secrets manager?
Access is an AWS API gated by IAM. New hires, Windows laptops, and frontend repos still end up with a file. Kryptic removes that file.
Can I use Kryptic and AWS Secrets Manager together?
Yes. Kryptic for people and pipelines you do not want to IAM. AWS for native AWS services.
Is Kryptic multi-cloud?
Yes. The daemon and machine identities do not require an AWS account.
