Worth paying once past the Free plan's 5-identity cap: the Pro plan costs $20/identity/month for unlimited identities and SAML SSO.
About
In practice. What you can do with Infisical.
Infisical centralizes secrets management for development teams, with secret versioning, dynamic secrets and rotation on higher plans. It also bundles two separately priced products: privileged access management with session recording, and certificate management with internal CAs and ACME support, plus SAML/OIDC SSO and SCIM provisioning.
The Free plan covers 5 identities and 3 environments at no cost, and the MIT-licensed core can be self-hosted. Paid Secrets Management starts at $20/identity/month on Pro, rising to $40 on Advanced for dynamic secrets and gateways; Privileged Access and Certificate Management are billed on top.
Practical uses
UsageA small dev team stores API keys and database credentials on the Free plan, syncing secrets across 3 environments for up to 5 identities.
UsageA growing company upgrades to Pro to add SAML SSO and secret versioning once it needs unlimited identities and 30-day audit log retention.

Pros and cons. What Infisical does well, and what to expect.
Pros
MIT-licensed open-source core can be self-hosted for free, avoiding vendor lock-in on the hosted Cloud offering.
SSO covers a wide range of named identity providers (Okta, Entra ID, Google, Keycloak, Auth0) rather than a generic SAML-only claim.
Cons
Total cost is hard to predict upfront since Secrets Management, Privileged Access and Certificate Management are three separately priced products.
The Free plan's 5-identity cap is reached quickly once both human and machine identities (CI jobs, services) are counted.
When it makes sense. Keep Infisical, or challenge it?
Keep if
You want centralized secrets management with the option to self-host, and you can live within 5 identities before paying.
Infisical becomes worthwhile when
+You use it at least once a week
+The monthly cost ($20) is small next to the time it saves you
Challenge if
You need dynamic secrets or gateways immediately, which require the $40/identity/month Advanced plan rather than the $20 Pro entry point.
Infisical becomes too expensive when
−You use it less than once a month
−A simple free version or a tool already in your stack would do
Our verdict. What to know about Infisical.
Why this verdict
Great
Added value
A usable free tier (5 identities, 3 environments) plus an MIT-licensed self-hosted core means a small team can run real secrets management at no cost before paying $20/identity/month on Pro.
Simplicity
Neutral score: the dossier lists plan limits and features but has no first-use or setup-time evidence for the hosted or self-hosted paths.
Fit for purpose
Delivers secrets management, SSO and certificate management as described, with SAML/OIDC support for named identity providers confirming the SSO claim.
Performance
Covers secrets management, privileged access management with session recording, and certificate management with internal CAs, a broad security scope for the category.
Reversibility
The MIT-licensed open-source core can be self-hosted, which gives a concrete exit path away from the hosted Cloud offering.
