What a SaaS actually needs

Six things every SaaS
can't ship without.

A landing page is not a SaaS. Real customers need isolation, billing, roles, admin tooling, and a portal — assembled from the start, not bolted on later.

Multi-tenancy

Every customer needs their own data, users, settings, and billing — strictly isolated from every other tenant. Get it wrong once and the company is over.

Row-level isolation, tenant-aware queries

Subscriptions & billing

Plans, prices, trials, dunning, invoicing, taxes, proration. Stripe handles charges — your app handles enforcing what each plan actually allows.

Stripe wired · subscriptions + usage

Auth & sessions

Sign-up, sign-in, password reset, OAuth, magic links, MFA, sessions, refresh tokens — plus invites, team membership, and account recovery flows.

JWT sessions · OAuth · password reset

RBAC & permissions

Owner, admin, member, billing-only, read-only. Every endpoint, page, button, and field needs to check who is allowed to see and do what — consistently.

Security profiles applied to every element

Admin dashboard

Internal tools to view tenants, impersonate users, refund charges, look up support tickets, watch real-time MRR. The thing your operations team lives in.

Backoffice with CRUD on every entity

Customer portal

Where the customer actually uses your product: dashboards, settings, team invites, billing self-service, API keys, usage limits, and account profile.

What Weezzi generates

The whole SaaS,
generated as one model.

Not just code snippets — a coherent application: schema, APIs, security, frontend, admin, billing, and the operating layer marketing edits live.

One application model.
Everything emitted from it.

Weezzi keeps the source of truth as a structured application model — entities, roles, pages, workflows. Production code is regenerated deterministically from the model, every time.

  • Tables, schema, migrations — kept in sync with the model
  • REST + GraphQL + OpenAPI — auto-generated, cached
  • RBAC, multi-tenancy, multi-language fields — built in
  • Admin pages, lists, forms, dashboards — for every entity
  • Customer-facing pages, components, navigation — generated
  • Java / Python / JavaScript extensions per element

Three steps · one afternoon

Prompt. Structure. Live app.

Each step in the build is visible and editable. You can drop into the prompt to refine, into the schema to adjust relations, into the live app to operate it — without leaving Weezzi.

A real example

B2B SaaS · Stripe + usage metering
+ admin dashboard.

Same prompt as the walkthrough, expanded. Here's everything Weezzi assembles around one application model — the surface you'd otherwise wire from Lovable + Supabase + Stripe Dashboard + Webflow + Phrase.

Anatomy of one prompt.

Marketing operates the live customer-facing site. Developers extend the differentiating logic in Java/Python/JS. Founders own the code and self-host on Docker or Kubernetes — at no recurring platform cost.
