KeyEnv vs OpenBao

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.

OpenBao is a free, open-source system for storing and controlling access to secrets such as API tokens, encryption keys, passwords, and certificates. Management is available through a web UI, CLI, or HTTP API. Key/value secrets are encrypted before persistent storage, while dynamic credentials can be generated for Kubernetes and SQL databases and revoked when leases expire. Leases can be renewed, and individual secrets or groups can be revoked. OpenBao also encrypts and decrypts data without retaining it. Authentication methods include GitHub, LDAP, and AppRole, with token-based policies. Its storage barrier uses AES-256-GCM and verifies authentication tags during decryption. High-availability configurations are supported. Deployment options include packages, containers, binaries, source builds, and Helm; documentation covers Linux, macOS, FreeBSD, and Windows. Releases provide GPG signatures and SBOMs. Integrated Storage defaults to a 1 MiB maximum entry size, configurable with max_entry_size.
