KeyEnv vs SikkerKey

KeyEnv manages environment variables and secrets across development workflows. Its CLI lets teams run, inject, and manage secrets from the terminal, while separate development, staging, and production configurations allow environment-specific overrides. A scanner checks for hardcoded keys, tokens, and passwords across more than 149 patterns. KeyEnv can schedule PostgreSQL and MySQL credential rotation using a two-secret approach intended to avoid downtime. Integrations include SDKs, GitHub Actions, Bitbucket Pipelines, serverless tools, and frameworks such as Next.js, Django, Laravel, Spring Boot, and Rails. The maker says secrets are encrypted on the device with AES-256-GCM and that it cannot access encryption keys or plaintext secrets; data in transit uses TLS 1.3, with Argon2id for key derivation. Access controls include roles, environment isolation, revocable scoped tokens, and audit logs. KeyEnv runs on Linux, macOS, web, API, and self-hosted deployments. The Free plan includes up to three projects and 100 secrets per environment. Team is $3.33/user/mo (annual) or $4.00 per user/month; new accounts get a 14-day Team-feature trial without a credit card.

SikkerKey is a secrets manager and vault for application and infrastructure credentials. It supports standard, structured, managed, leased, certificate, canary, and TTL secrets, as well as secret rotation and dynamic secrets. Machines authenticate by signing each request with an Ed25519 private key that stays on the host. Teams can connect it to CI/CD, containers, app platforms, serverless functions, servers, and on-premise systems through its CLI, SDKs, or signed HTTP. Official SDKs are available for Go, Python, Node.js,.NET, Kotlin, and PHP. Its CLI supports Linux x64 and ARM64, macOS Intel and Apple Silicon, and Windows x64. The service describes a three-layer encryption design; its MCP server gives AI agents a separate identity class that cannot retrieve plaintext secret values. SikkerKey says its vault, secrets, and audit trail stay in the EU and are operated from Denmark. The free Developer plan is free and includes 10 machines; paid plans start at $29/mo. Every plan includes direct in-dashboard support and unlimited secret, project, read-volume, and rotation counts.
