The problem

Every SaaS begins with the same six weeks of work.

Before a single feature that makes your product different, you rebuild the same layer: sign-up, sessions, roles, tenants, plans, invoices, emails, an admin area. It is required, it is well understood, and it is not your product.

  • Auth written for the fifth time

    Refresh rotation, verification, reset, revocation.

  • Tenancy bolted on too late

    Retro-fitting isolation costs more than building it.

  • Billing that never quite reconciles

    Webhooks, proration, plan state, failed payments.

  • An admin area built last, badly

    Support requests arrive before the tooling does.

What's inside

Sixteen modules, grouped into four layers.

Select any module to see exactly what ships inside it. Status is stated honestly — included today, in progress, or planned.

  • Included
  • In progress
  • Roadmap

Identity & access

4 modules

Everything between a visitor and an authorised session.

  • Email + password with hashed credentials
  • Refresh-token rotation and session revocation
  • Email verification and password reset flows
  • Google OAuth sign-in

Tenancy & billing

4 modules

The commercial layer that turns an app into a SaaS.

Application & admin

4 modules

The screens your users and your support team live in.

Platform & delivery

4 modules

What it takes to get it live and keep it live.

Architecture

A structure you can read in an afternoon.

Feature-first Angular, module-per-domain NestJS, one shared types package. No generated black boxes — every file is yours to open and change.

Layer 01

Angular client

  • Standalone components, signals, lazy routes
  • Auth interceptor, route guards, tenant context
  • Tailwind 4 + DaisyUI 5 theming

Layer 02

NestJS API

  • Domain modules, DTO validation, guards
  • RBAC policies and tenant scoping at query level
  • OpenAPI schema generated from decorators

Layer 03

Data & services

  • PostgreSQL via Prisma, migrations committed
  • Stripe, SMTP provider, object storage adapters
  • Redis queue for email and webhook retries

Project tree

apps/api/src/common/guards/tenant.guard.ts

@Injectable()
export class TenantGuard implements CanActivate {
  constructor(private readonly tenants: TenantService) {}

  async canActivate(ctx: ExecutionContext): Promise<boolean> {
    const req = ctx.switchToHttp().getRequest<AuthedRequest>();
    const tenantId = req.headers['x-tenant-id'];
    if (!tenantId) throw new BadRequestException('Missing tenant');

    const member = await this.tenants.findMember(tenantId, req.user.id);
    if (!member) throw new ForbiddenException('Not a tenant member');

    req.tenant = member.tenant;
    req.role = member.role;
    return true;
  }
}

Stack & versions

Build vs buy

The work already done, itemised.

Estimates reflect a mid-level full-stack developer building each module to production quality — including tests, edge cases and documentation. Apply your own rate; we won't guess it for you.

Total engineering time replaced244 hours

At a modest $40/hour that layer costs roughly $9,760 to build once. The starter replaces it for $79 — and you still own and control every line.

A strong fit if you are…

  • A SaaS founder shipping an MVP — you need paying customers this quarter, not a rebuilt auth module.

  • A freelancer or agency — the same foundation is reused across client projects under one licence.

  • An Angular or NestJS developer — the conventions will look familiar from day one.

  • A team building internal B2B tools — tenancy, roles and admin are exactly what internal tools need.

  • Someone who has built this before — you already know how long that layer takes.

Probably not for you if…

  • You need React, Vue or Next.js — this is an Angular + NestJS codebase and will not be ported.

  • You want a no-code product — this is a source codebase for developers, not a hosted builder.

  • You need a finished niche app — it is a foundation; your domain features are still yours to build.

  • You have never used a TypeScript monorepo — the docs are thorough, but some framework familiarity is assumed.

We would rather lose the sale than sell you the wrong foundation. Source code is non-refundable, so read this list twice.

Use cases

Three ways buyers put it to work.

  • Agency

    Client SaaS delivered in weeks

    Rebrand the theme, replace the domain modules, keep auth, tenancy and billing untouched. Deliver a working product while a from-scratch build is still in setup.

    One licence covers unlimited client projects

  • Founder

    MVP in front of buyers sooner

    Start with working sign-up, plans and checkout, so your first week is spent on the feature that makes the product worth paying for.

    Charge customers from the first release

  • Internal tools

    B2B platform for multiple business units

    Multi-tenancy maps cleanly onto departments or subsidiaries, with RBAC controlling what each group can see.

    Roles and isolation handled on day one

Documentation

Running locally in four commands.

The docs site covers setup, environment variables, tenancy model, billing flow, RBAC policies, email templates and deployment — the same docs used to build the live demo.

git clone <your-private-repo> saas && cd saas
cp .env.example .env
docker compose up -d   # postgres + redis
pnpm install && pnpm db:migrate && pnpm dev
