Strengths and weaknesses
- +Transparent usage-based pricing with a large 10,000-MAU free tier and no hard pricing cliffs
- +No feature gating: SSO, SCIM, RBAC, MFA, passkeys, and M2M available even on the free plan
- +Highly rated developer experience and SDK quality, repeatedly cited by Auth0 migrators
- –Integrating with legacy/on-prem identity providers is difficult and sometimes impractical
- –Several reviewers report relying on support more often than they'd like for non-trivial setups
- –Removing Stytch branding on certain emails is a paid ($99) add-on that annoys some developers
- +Deep Postgres Row-Level Security integration: JWT claims are usable directly inside SQL policies for DB-layer authorization
- +Very generous free tier (50,000 MAU) and low overage pricing ($0.00325/MAU) versus Auth0/Okta
- +Broad auth methods out of the box: password, magic link, OTP, phone, anonymous, dozens of social OAuth providers, plus TOTP/phone MFA
- –B2C-first: no first-class Organizations model and no SCIM provisioning for B2B tenancy
- –SAML/OIDC support is comparatively immature; SSO gated to Pro and above
- –No adaptive/risk-based MFA or bot-detection capabilities
