Multi-Tenant SaaS Dashboard

One dashboard to run teams, workspaces, projects, and billing.

01 · The problem

Organizations often stitch together separate tools for auth, project management, and billing. This dashboard is a multi-tenant workspace platform that lets an organization securely manage teams, workspaces, projects, and user roles from a single, centralized application.

Backend

Database

MongoDB

Chosen for a flexible document structure, easy schema evolution, and a natural fit for nested workspace/project data — with Prisma layered on top for type-safe access.

Authentication

Auth.js (NextAuth)

Session-based auth, protected routes, secure login flow.

Authorization

RBAC — Admin, Manager, Member

Permission checks happen before a user can reach a protected resource.

Billing

Stripe

Subscription plans, recurring payments, premium workspace tiers.

Deployment

Vercel

Automatic CI/CD, serverless deployment, fast global CDN.

04 · Challenges & solutions

Challenge

Prisma 7 removed support for directUrl inside the schema file, which broke migrations and deployments that depended on it.

Solution

Migrated the connection configuration into prisma.config.ts, updated the Prisma client generation process, and adjusted environment variables to match Prisma 7's new configuration — restoring migrations and deploy compatibility.

Challenge

Enforcing multi-tenant data isolation so one workspace could never see another's data.

Solution

Every workspace owns its own projects and users. Each request validates workspace ownership before returning any data, preventing cross-workspace access.
