Feature	NoxKey	HashiCorp Vault
Designed for	Individual developers on macOS	Teams and infrastructure
Storage	macOS Keychain (Secure Enclave)	Server-side encrypted storage
Infrastructure required	None — runs locally	Server, storage backend, TLS certs
Setup time	30 seconds	Hours to days (production-ready)
Authentication	Touch ID (biometric)	Tokens, AppRole, LDAP, OIDC, etc.
AI agent detection	Yes — process-tree walking	No
Encrypted handoff	Yes	No
Dynamic secrets	No	Yes — database, cloud, PKI
Secret rotation	Guided manual rotation	Automatic (dynamic secrets)
Audit logging	macOS Console logs	Full audit trail with metadata
Price	Free (MIT open source)	Free (OSS) / $$$$ (Enterprise)
Maintenance	Zero	Ongoing ops: unsealing, upgrades, backups

When to choose NoxKey

• You're a solo developer or small team and need secrets on your local machine — not across infrastructure
• You don't want to run a server just to store API keys for development
• You use AI coding tools and want secrets protected from context window exposure
• You want to replace .env files with something encrypted and authenticated

When to choose Vault

• You need dynamic secrets — auto-generated database credentials, cloud tokens, PKI certificates
• You need cross-platform — Vault works on Linux, Windows, macOS, and in containers
• You need team-scale access control — policies, namespaces, audit trails
• You're managing production infrastructure — Vault is built for servers, not developer laptops

They work together

NoxKey and Vault aren't mutually exclusive. Use Vault for your production infrastructure and NoxKey for your local development secrets. Store your Vault token in NoxKey so it's protected by Touch ID instead of sitting in ~/.vault-token as plaintext.
