Argentinian-founded, San Francisco company. Pricing based on MAU (Monthly Active Users) gets expensive fast — triggered the "Auth0 revolt" of 2023 when prices were hiked without warning. Competition on the SaaS side: Clerk (DX-focused, modern stack), Stytch, FusionAuth, Frontegg. Self-host alternatives: Keycloak, Authentik.
