Infisical vs Phase

Infisical is an identity security platform for managing application secrets, certificates, and privileged access across cloud, on-prem, and AI infrastructure. Secrets Management centralizes credentials for syncing, rotation, and auditing across environments and workloads, with role-based access scoped by environment, path, and identity. Secrets can be rotated on a schedule or issued as short-lived credentials. Certificate Management handles private certificate authorities and automates certificate issuance, renewal, and revocation. Privileged Access provides short-lived identity-based sessions with auditing, while Agent Proxy keeps real secrets at the proxy and gives agents placeholders, with requests logged. Infisical lists integrations including AWS, Azure Key Vault, GitHub, GitLab, Datadog, OpenAI, and PostgreSQL. It can be used as Infisical Cloud or self-hosted. A free plan is available; paid plans start at $20 a month billed annually. The free certificate plan is limited to 10 active certificates, up to 5 SANs per certificate, and no wildcard SANs.

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.
