Strengths and weaknesses
- +Multi-tenancy is a first-class primitive: per-tenant users, roles, SSO, branding and policies out of the box
- +Fast time-to-value; reviewers call it plug-and-play with hosted login live in hours
- +Entitlements engine ties feature-gating to subscription plans, well-suited to SaaS monetization
- –Limited customization of the hosted/embedded login UI for teams with strict branding needs
- –Cannot bring your own user database (no self-hosted data store)
- –Webhooks are not very customizable
- +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
