KeyEnv vs Secrets Manager

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.

Secrets Manager is a free, open-source, self-hosted system for storing application secrets in encrypted form, managing them through a web interface, and injecting them into processes with a command-line tool. Users organize secrets by organization, project, and environment, import.env files, edit or reveal values, keep versions, roll back, and soft-delete entries. The `secrets run` command supplies environment secrets to a child process and its descendants without creating a.env file. Documented workflows cover Node.js, Python, npm, and Next.js; CI or deployment can use an API URL, token, and environment ID. User and service-account grants can be scoped to projects or environments, and revealing values requires explicit permission. AES-256-GCM envelope encryption uses a separate data key per value, while plaintext values are not stored in the database. Audit events include secret reveals, and values are withheld if audit writing fails. Docker Compose starts PostgreSQL, Redis, backend, and frontend; local Kubernetes manifests are also provided. A user-generated master key is mandatory and lost keys make secrets unrecoverable. The repository is MIT licensed.
