Every piece of data in Backside.app belongs to a tenant. Tenants are isolated at the database level — it is physically impossible for one tenant’s API request to return another tenant’s data.

​
How it works

  1. Your API key is tied to a tenant
  2. Every request sets a tenant context at the database level
  3. PostgreSQL Row-Level Security (RLS) filters every query automatically
  4. Even a bug in our code cannot leak cross-tenant data

​
Tenant provisioning

Tenants are created automatically:
  • Stripe path: First subscription creates the tenant and returns an API key
  • x402 path: First payment from a new wallet creates the tenant
