Infisical
MIT-licensed, open-source secrets management platform that has grown into certificates (PKI), KMS, secret scanning, privileged access and AI-agent credential brokering, available as Infisical Cloud or self-hosted.
Quick answer
What is Infisical?
Short answer
Infisical describes itself as "security infrastructure for developers and AI agents". The core platform is open source under the MIT licence (an /ee directory holds licensed enterprise features) and covers secrets management with dynamic secrets and rotation, certificate management with ACME/SCEP/EST issuance, key management (KMS), secret scanning, privileged access management with recorded sessions, and an agent proxy so "the credential never enters the agent's context". Secrets are delivered via CLI, SDKs, a Kubernetes operator or API, with documented integrations across AWS, GCP, Azure, Kubernetes, Terraform, GitHub Actions, GitLab CI, Jenkins, Vercel, Cloudflare and HashiCorp Vault. Deploy on Infisical Cloud (US/EU) or self-host via Docker, Docker Compose, Kubernetes Helm, Linux package, AWS ECS or GCP GKE. The vendor reports securing "10 billion secrets every day" for customers including Databricks, LG Electronics, UPS and Hugging Face.
- Best for
- Engineering and platform teams that want an open-source-first secrets and machine-identity platform with a free tier and a clear path to self-hosting.
- When to choose
- You want an open-source secrets and machine-identity platform you can start free, self-host, and grow into PKI and PAM without switching vendors.
- When not to choose
- You need a long-established enterprise PAM/PKI stack today, or your identity count makes per-identity pricing uneconomic versus a cluster-priced vault.

Categories
Common use cases
- Application and infrastructure secrets management
- Dynamic secrets and automated rotation for databases and cloud accounts
- Internal PKI and automated certificate renewal (ACME/SCEP/EST)
- Secret scanning across repositories and infrastructure
- Brokering third-party API credentials for AI agents
- Session-based privileged access to databases and servers
Strengths
- MIT-licensed core with published, transparent pricing and a free cloud tier
- Very broad documented integration list across CI/CD, cloud providers, frameworks, databases and AI providers
- Multiple self-hosting paths (Docker, Helm, Linux package, AWS ECS, GCP GKE) plus US and EU cloud regions
- Single platform spanning secrets, PKI, KMS, PAM and secret scanning
Limitations & considerations
- Dynamic secrets, gateways and full rotation are gated to the Advanced tier and above
- Enterprise-only features (LDAP, SCIM, groups, approval workflows, SSO on self-hosted) require a licence even when self-hosting
- Per-identity pricing can scale quickly for machine-identity-heavy estates
- PAM and PKI modules are newer than the core secrets product
