In their own words
Phase
Phase is an open-source platform for managing application secrets from development through production. It runs as a managed cloud service or on your infrastructure, including in air-gapped environments. Phase says end-to-end encryption is enabled by default, with servers storing ciphertext in that mode. Its CLI keeps secrets encrypted at rest locally and can inject them while offline; it also installs skills for Claude Code, Codex, Cursor, OpenCode, and VS Code Copilot to work with secrets using natural language. Teams can assign managed or custom roles by app and environment, set IP allow-lists, review records of access and changes, and use point-in-time rollback. Integrations include AWS, Azure, HashiCorp Vault, Docker, Kubernetes, Cloudflare, GitHub, GitLab, Vercel, and Railway. Phase lists SOC 2 Type 2 and penetration testing by Oneleet. The Free plan is limited to 5 users or service accounts, 3 apps, and 3 environments. Pro costs $10 per month, billed annually at $120 ($144 shown), with a 14-day trial.
