pip install phase-cli
Plug and play integration
Inject secrets scoped only to your app as environment variables during runtime. Use process.env / os.environ.get to read them — no dependencies or code changes required.
Simplify development
Effortlessly maintain separation between dev, staging, prod environments and quickly switch in between them. Avoid using production secrets in development.
Always in sync
Import secrets from .env files and securely sync them with your team. Eliminate ad-hoc secret coordination with other teams over Slack.
Secure by default
The Phase CLI uses end-to-end encryption with private-key sharding via secret sharing schemes to avoid a single point of compromise.
Keyring integration
Phase CLI uses keyring backends such as macOS Keychain, Windows Credential Locker, KDE Wallet, GNOME Keyring and more to safely handle secret zero.
Works where you work
The Phase CLI works on your laptop, CI, Docker containers, Virtual Machines and Kubernetes clusters.
