Overview

Overview

Phase is built for engineering teams that need to store, rotate, and audit application secrets safely across the entire software lifecycle. The platform offers a web console for visual secret management, a powerful CLI for importing .env files and injecting secrets at runtime, and SDKs for Go, Node.js, and Python.

Features & Deployment

Secrets are encrypted client‑side and synced automatically to GitHub, Vercel, Cloudflare Pages, AWS Secrets Manager, and other services. Role‑based access control lets you define fine‑grained permissions per application and environment. For Kubernetes workloads, the Phase Secrets Operator updates secrets in‑cluster and triggers pod reloads without downtime. Terraform integration enables secret provisioning alongside infrastructure code. Phase can be run as a SaaS offering on Phase Cloud or self‑hosted via Docker Compose, Helm charts, or native cloud deployments (AWS, GCP, Azure, DigitalOcean). The open‑core model provides a free community edition under the MIT license, while advanced enterprise features reside in a separate licensed module.

Pros

  • End‑to‑end encryption protects secrets at rest and in transit
  • Granular role‑based access control per app and environment
  • Versioned secret history with diff and restore capabilities
  • Official SDKs for Go, Node.js, and Python

Considerations

  • Enterprise‑only features require a commercial license
  • Self‑hosting demands infrastructure and ops expertise
  • RBAC policy configuration can be complex for newcomers
  • Limited UI theming and branding options

Fit guide

Great for

  • Fast‑moving dev teams needing secure secret rotation
  • Organizations adopting GitOps with Terraform or Helm
  • Kubernetes‑centric deployments that require live reloads
  • Teams that prefer self‑hosted control over their data

Not ideal when

  • Simple scripts with a single static secret
  • Teams without resources to manage self‑hosted infrastructure
  • Projects that need deep UI customization or branding
  • Environments that rely on built‑in secret scanning tools

How teams use it

CI/CD pipeline secret injection

Secrets are automatically synced to GitHub Actions, Vercel, and other pipelines, removing manual handling and reducing risk.

Kubernetes secret rotation

The Phase Secrets Operator updates in‑cluster secrets and triggers pod reloads without downtime, ensuring continuous security compliance.

Multi‑environment configuration management

Developers switch between development, staging, and production environments with versioned secrets, view diffs, and restore previous values instantly.

Infrastructure as code secret provisioning

Terraform provider stores secrets alongside resources, keeping infrastructure and configuration in sync and auditable.

Frequently asked questions

How are secrets protected in transit and at rest?

Phase encrypts secrets client‑side before storage and transmits them over TLS, providing end‑to‑end encryption.

Can I self‑host Phase?

Yes, Phase can be deployed via Docker Compose, Helm chart, or native cloud services such as AWS, GCP, Azure, and DigitalOcean.

What languages are supported for SDK integration?

Official SDKs are available for Go, Node.js, and Python, with additional community SDKs planned.

How does role‑based access control work?

Permissions are defined per user, organization, application, and environment, enforced cryptographically to ensure only authorized access.

Is there a free tier?

The core platform is open‑source under the MIT license; the community edition is free, while Pro/Enterprise features require a commercial license.
