SaaS Builder

Launch Your SaaS Product in Days, Not Months

Build SaaS applications on a starter that already has user authentication, a Stripe subscription schema and a D1 database. Team management, admin screens and transactional email are not in the template - describe them and the AI generates them into the same project.

  • No coding required
  • Database included
  • Deploy instantly
Key takeaways
  • The Stripe starter ships auth, a subscription and payment schema, and a D1 database already wired together
  • Teams, organizations, admin screens and email are generated on request - they are not in the starter schema
  • A generated app has no mail provider until you connect one, so nothing is emailed by default

Everything you need to build

User Authentication

Complete auth system with signup, login, and revocable sessions. Ask for password reset or social providers and they are generated too.

Subscription Billing

Stripe integration with multiple plans, trials, upgrades, and billing portal.

Team Management on Request

Not in the starter schema, which is single-user. Ask for organizations, invites and roles and the AI adds the tables, middleware and screens.

Admin Dashboard on Request

Describe the admin screens you want - user list, subscription status, activity - and they are generated against your own tables.

Email Needs a Provider

Generated apps ship no mail provider, so nothing is sent until you connect one. Add your provider and the AI writes the sending code and templates.

Security Basics in the Template

Passwords are bcrypt-hashed and sessions are signed JWTs that can be revoked server-side. Rate limiting and other hardening are things to ask for.

In-depth guide

Building Complete SaaS Products with Fabricate

A complete SaaS product requires many pieces working together: user authentication, subscription billing, a database, email sending, and a reliable hosting infrastructure. Most SaaS founders spend weeks or months wiring these together before writing a single line of product-specific code. Fabricate generates the entire stack from a description. The output includes email and password authentication generated into the project, Stripe for subscription management with a customer portal, a D1 SQLite database with a proper schema, and deployment to Cloudflare's global edge—all connected and working.

Authentication Layer: email and password sign-up and login, bcrypt password hashing, and revocable JWT sessions stored in D1. Organization accounts, social providers, and role-based permissions are generated on request.

Billing Infrastructure: Stripe subscription plans, free trial support, usage-based billing options, upgrade/downgrade flows, and Stripe customer portal for self-service.

Data and Backend: D1 SQLite database with typed Drizzle ORM queries, Cloudflare Workers API routes, and KV for caching.

Frequently Asked Questions

What billing features are included?
Full Stripe integration: multiple subscription tiers, free trials, plan switching, invoices, and customer portal. Everything you need for SaaS billing.
Can I have team/organization features?
Yes, on request. The starter schema is single-user - users, sessions, subscriptions, payments - so team workspaces, invites and role-based permissions are generated when you describe them, not inherited from the template.
Is multi-tenancy supported?
It is generated, not pre-built. The AI adds an organization table and scopes queries and route guards to it. Tenant isolation is application logic in your own code, so review it - it is the part worth reading line by line.
What about email notifications?
A generated app has no mail provider, so no email is sent by default. Connect a provider and ask for the emails you want - welcome, password reset, billing - and the AI writes the sending code and templates against it.
Can I offer a free trial?
Yes. Configure trial periods, credit card requirements, and automatic conversion to paid plans.
Is it white-label ready?
Yes. Customize branding, colors, and domain to make it fully your own product.
