Self-host & SaaS

Authix supports single-tenant (your product only) and multi-tenant (many customers on one deployment).

Environment

Legacy Vercel projects may still use KEYVAULT_* variables; Authix reads AUTHIX_* first with automatic fallback.

Tenant isolation

Each signup creates an organization (your app). That org gets its own admin and reseller system roles, team, products, licenses, webhooks, audit log, and sessions — the same admin capabilities as before, but isolated from other tenants.
