SaaS Builder

Launch Your SaaS Product in Days, Not Months

Build SaaS applications on a React 19 app with its own SQLite database in a Durable Object, and user accounts built in as soon as the app needs them. Stripe billing, team management, admin screens and transactional email are not pre-wired - describe them and the AI generates them into the same project.

  • No coding required
  • Database included
  • Deploy instantly
Key takeaways
  • Every app gets its own SQLite database in a Durable Object; user accounts are built in when the app needs per-user data, wired to that same database
  • Stripe billing, teams, organizations, admin screens and email are generated on request - they are not pre-wired
  • A generated app has no mail provider until you connect one, so nothing is emailed by default

Everything you need to build

User Authentication

Built-in auth with signup, login, and server-side cookie sessions. Added when the app needs accounts. Password reset needs an email provider; social sign-in is not built in.

Subscription Billing

Ask for plans, trials, upgrades, and a billing portal and the AI writes the Stripe code. You add your own Stripe keys.

Team Management on Request

Not built in: accounts are per-user by default. Ask for organizations, invites and roles and the AI adds the tables, checks 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 Built In

Passwords are PBKDF2-hashed, sessions are opaque HttpOnly cookies, and CSRF checks and login lockout are built in. Rate limiting is something 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 built-in email and password accounts, a SQLite database in the app's own Durable Object, Stripe subscription code with a customer portal when you ask for billing, and publishing to Cloudflare's global edge—all connected and working.

Authentication Layer: email and password sign-up and login, PBKDF2 password hashing, HttpOnly cookie sessions stored in the app's SQLite database, CSRF checks, and login lockout. Organization accounts, social providers, and role-based permissions are generated on request.

Billing Infrastructure, on request: the AI writes Stripe code for subscription plans, free trials, usage-based billing, upgrade/downgrade flows, and the Stripe customer portal. You add your own Stripe keys, which only the published app receives.

Data and Backend: the built-in SQLite database of the app's Durable Object, queried from plain TypeScript server routes on Cloudflare Workers.

Frequently Asked Questions

What billing features are included?
None is pre-wired. Ask for billing and the AI writes Stripe code for subscription tiers, free trials, plan switching, invoices, and the customer portal. You add your own Stripe keys, which only the published app receives.
Can I have team/organization features?
Yes, on request. Built-in accounts are per-user, so team workspaces, invites and role-based permissions are generated when you describe them, not inherited from a 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. Ask for trial periods, card requirements, and automatic conversion to paid plans, and the AI writes them with Stripe subscriptions.
Is it white-label ready?
Yes. Customize branding, colors, and domain to make it fully your own product.
