| Pricing | From $35/month (B2C Essentials at 500 MAUs); B2B Essentials starts at $150/month at 500 MAUs · free tier: $0/month for up to 25,000 MAUs (B2C and B2B), 1 custom domain (card verification), passwordless, unlimited social connections, 5 Organizations, 1 Enterprise Connection, self-service SSO and SCIM, community support; no credit card to sign up | From $25/mo (Pro) — vendor-domain explainer, not verified on the billing page · free tier: Free "Hobby" plan covering 50,000 monthly retained users; all features free in development mode |
| Pricing model | Subscription (tiered by Monthly Active Users, with add-ons) | Subscription (metered on monthly retained users) |
| Best for | Development teams under roughly 10,000 MAUs, or B2B SaaS vendors needing Organizations plus a handful of SAML connections who can absorb $150–$2,400/month; also regulated buyers willing to buy at Enterprise for the 99.99% SLA, HIPAA/BAA and FAPI profile. | React/Next.js product teams shipping B2B SaaS or paid B2C below roughly 50k retained users, who value time-to-launch over auth-layer control, have engineers able to work around component styling limits, and whose incident tolerance can absorb slow vendor support. |
| Avoid if | You run a high-MAU consumer platform (above ~30,000 B2C MAUs pricing is sales-only), you are a cost-sensitive startup on a steep growth curve exposed to the next-tier-up billing rule, you need predictable spend forecasting, or you are a B2C buyer needing enterprise SAML connections below the Enterprise tier. | You run a non-JavaScript stack, need deep domain-specific authorization, operate a free/ad-supported or high-churn consumer app at scale, need Clerk to be your billing system today, or carry hard support SLAs and regulated uptime obligations. |

A higher TOP SCORE means more of the evidence favours that platform on this methodology — it is not a recommendation, and it does not account for your specific requirements. Advertisers are never declared the winner of a comparison.
