Envless vs AWS Secrets Manager
A developer-first, end-to-end encrypted secrets manager compared with AWS's IAM-native secrets store.
Envless is a good AWS Secrets Manager alternative if you want client-side end-to-end encryption and a workflow built around developers and .env files rather than the AWS console. Envless encrypts variable values on your device before upload, so the server only ever stores ciphertext. AWS Secrets Manager encrypts secrets at rest with AWS KMS, where AWS manages the keys, and is deeply integrated with IAM, CloudTrail, and automatic rotation. Pick Envless for a portable, cross-stack workflow with typed SDKs, a CLI, and a free tier. Pick AWS Secrets Manager if you are standardized on AWS and want IAM-native access and built-in credential rotation.
Swipe the table sideways to see every column.
| Capability | Envless 21 / 21 | AWS Secrets Manager 5 / 21 fully |
|---|---|---|
| Encryption | ||
| Client-side end-to-end encryption | AES-256-GCM, PBKDF2-SHA256 200k iterations, per-workspace salt | Encrypts server-side via KMS; not client-side E2E |
| Zero-knowledge server storage | Server stores ciphertext only; never sees plaintext or passphrase | AWS/KMS can decrypt; not zero-knowledge |
| Workspace key rotation | Set, verify, rotate, and clear workspace passphrases | Automatic secret + KMS key rotation, but no workspace key model |
| Developer tooling | ||
| Typed runtime SDK import | TypeScript import with auto coercion, no .env files | Typed AWS SDK, but secrets returned as untyped strings/JSON |
| Generated type declarations | envless types emits envless-env.d.ts for compile-time checks | No generated type definitions for stored secrets |
| Server/client secret separation | Enforced via bundler plugin, ESLint, runtime checks | No built-in server vs client secret split |
| Sync | ||
| Sync to .env files | envless sync writes idempotent .env.<slug> files | No native .env sync; requires third-party tooling |
| Process wrapping | envless run injects vars into a child process, no disk | No native CLI command to wrap a process with injected secrets |
| Multi-environment merging | run and build merge environments, later wins; sync writes one file each | Separate secrets per env, but no built-in merge layering |
| Performance | ||
| On-disk encrypted caching | On-disk ciphertext cache, 0600, 15-minute freshness window | Client/Lambda caches are in-memory, not on-disk encrypted |
| Offline fallback | whoami serves the cached profile when the API is unreachable | Requires network/IAM access; no offline fallback |
| Integrations | ||
| Framework integrations | Next.js, Vite, Node, Bun, Cloudflare/Vercel/Netlify edge | Integrates via ECS/Lambda/EKS CSI; limited web framework support |
| CI/CD and deploy targets | GitHub/GitLab/CircleCI, Vercel, Docker, K8s, Fly, Railway, Render | Works with CodePipeline/CodeBuild and ECS/Lambda/EKS targets |
| Versioning | ||
| Variable versioning and rollback | Snapshots with notes, full history, one-click rollback | Version stages (AWSPREVIOUS) allow rollback |
| Workspace change history | Attributed per-variable history; every change sent as a signed webhook | All access logged via CloudTrail |
| Access control | ||
| Role-based access control | Owner/Admin/Viewer plus custom roles, 44 permissions | Fine-grained IAM policies and resource policies |
| Scoped API keys | Per-resource read/write/none scopes, SHA-256 hashed | IAM credentials scoped by policy; not native API keys |
| API | ||
| REST API with bulk ops | Full CRUD plus bulk variable create/delete | AWS API incl. BatchGetSecretValue for bulk reads |
| Automation | ||
| Signed webhooks | 48 events, HMAC-SHA256 (Standard Webhooks), retries | No signed webhooks; uses EventBridge events instead |
| Authentication | ||
| CLI device-code auth | Browser OAuth device flow, locally cached tokens | IAM Identity Center SSO supports device login flow |
| Multi-provider sign-in | Email, Google, GitHub OAuth, and email OTP | Federated SAML/OIDC via IAM Identity Center |
Choose Envless when
- You want true end-to-end encryption where values are encrypted client-side and the server never sees plaintext.
- Your stack is multi-cloud or local-first and you do not want secrets coupled to AWS IAM.
- You want typed SDKs, a CLI, and a workflow that maps directly onto .env files and environments.
- You want versioning and an attributed change history on every variable without wiring up CloudTrail.
- You want a free tier with no credit card to start and predictable flat pricing as you grow.
Choose AWS Secrets Manager when
- Your infrastructure already lives in AWS and you want IAM-native access control out of the box.
- You need built-in automatic rotation of database and service credentials.
- You rely on tight integration with other AWS services, KMS, and CloudTrail auditing.
- You prefer a fully AWS-managed service governed by your existing AWS account and billing.
Envless vs AWS Secrets Manager FAQ
Common questions about comparing and switching.
Yes, if you want client-side end-to-end encryption and a developer-first workflow that is not tied to AWS. Envless encrypts values on your device before upload and gives you typed SDKs, a CLI, versioning, and role-based access control. AWS Secrets Manager remains a strong choice when you are standardized on AWS and want IAM-native access and automatic rotation.
Envless encrypts variable values client-side, so the server stores only ciphertext and never sees plaintext. AWS Secrets Manager encrypts secrets at rest using AWS KMS, where AWS manages the encryption keys. Both use TLS in transit; the difference is who can technically decrypt the stored data.
No. Envless uses its own role-based access control and scoped API keys rather than AWS IAM. If IAM-native authorization is a hard requirement, AWS Secrets Manager fits that model more naturally. Envless trades that coupling for a portable workflow that works the same across local, CI, and any cloud.
Not today. Envless is a hosted platform and self-hosting is being explored. AWS Secrets Manager is a managed service that runs within your AWS account and region. If you need data to stay within your own AWS boundary, that is a point in AWS's favor. If you have a specific storage-region requirement, talk to us and we will confirm what we can support.
