Build a SaaS App
with AI

Auth, billing, dashboards, and admin panels—generated from a prompt. Get your subscription software in front of users fast.

Use Agent Mode for complex multi-screen SaaS apps. Enable Clerk for auth, Stripe for billing, and Supabase for data. GenMB handles the wiring.

What Goes Into a SaaS App?

A SaaS application is software delivered as a service—users sign up, subscribe to a plan, and access your product through the browser. At minimum, you need authentication (so users can create accounts), billing (so you can charge them), and a dashboard (so they can use the product).

Most SaaS apps also need an admin panel for you to manage users and content, role-based access to gate features by plan tier, onboarding flows to reduce churn, and settings pages for user preferences. Building all of this from scratch takes months.

GenMB generates these components together as a working application. You describe your SaaS concept, enable the relevant plugins (Clerk, Stripe, Supabase), and get a functional v1 with the core infrastructure already connected. It is not a template—the code is generated specifically for your product.

Everything a SaaS Needs, Generated

GenMB generates the full stack—auth, billing, data, and UI—so you can focus on what makes your product unique.

Complete Auth Stack

Google OAuth, Clerk integration, signup/login flows, password reset, and session management. Enable the Clerk plugin and GenMB generates the full authentication layer—registration, protected routes, and user profiles.

Subscription Billing

Stripe recurring payments, plan tiers, and usage metering. Enable the Stripe plugin to generate checkout flows, billing portals, and webhook handlers. Define your pricing tiers and GenMB wires up the payment logic.

Admin Dashboard

User management, analytics views, and application configuration. GenMB generates admin panels with data tables, charts, and controls so you can manage users, monitor usage, and configure your SaaS from day one.

Code Ownership

Export your entire codebase and self-host whenever you want. No vendor lock-in, no proprietary runtime. The generated code uses standard React and Node.js patterns that any developer can pick up and extend.

How to Build a SaaS App with GenMB

Five steps from idea to deployed subscription software.

1

Define Your SaaS Concept and Pricing Tiers

Decide what your SaaS does, who it serves, and how you'll charge. Define 2-3 pricing tiers (e.g., Free, Pro, Business) with clear feature boundaries. This clarity upfront leads to better generated code.

2

Describe the Full App to GenMB

Write a detailed prompt covering your core features, user roles, and key screens. For complex multi-screen SaaS apps, use Agent Mode—it breaks your vision into steps and builds each part autonomously, handling the coordination between screens and components.

3

Enable Clerk for Auth and Stripe for Billing

Activate the Clerk plugin for authentication and the Stripe plugin for subscription billing. GenMB generates the integration code—login/signup flows, protected routes, checkout pages, and billing portal access.

4

Connect Supabase for User Data

Use the Schema Designer to define your data models (users, subscriptions, app-specific data) and connect Supabase as your database. GenMB generates the data layer with proper relationships and access patterns.

5

Deploy and Start Onboarding Users

Deploy to a subdomain with one click. Share your SaaS with early users, collect feedback, and iterate. When you outgrow the initial version, export the code and continue development with your own team.

SaaS Builder Questions

Can AI build a production-ready SaaS?▼
GenMB generates a functional SaaS v1 with auth, billing, dashboards, and data management. It is a strong starting point for validating your idea and onboarding early users. For high-scale production with thousands of concurrent users, you should export the code and work with professional developers to optimize performance, add monitoring, and harden security. Think of GenMB as the fastest way to build your first version, not the last tool you will ever need.
How do I add subscription billing?▼
Enable the Stripe plugin in GenMB. Describe your pricing tiers (e.g., Free with limited features, Pro at $29/month, Business at $99/month) in your prompt. GenMB generates Stripe Checkout integration, a billing portal for customers to manage their subscription, webhook handlers for payment events, and plan-gated UI that shows or hides features based on the user's active plan.
Can I have different feature access per plan?▼
Yes. GenMB supports role-based access control through the RBAC service. Define your roles (free, pro, admin) and GenMB generates middleware and UI guards that restrict features by plan level. The admin dashboard lets you manage roles and override access when needed.
What happens when I need to scale?▼
Export your code at any time. The generated codebase uses standard frameworks (React, Next.js, Node.js) with no proprietary dependencies. Your developers can deploy it to any hosting provider, add caching layers, optimize database queries, and implement the infrastructure changes needed for scale. The GenMB-generated code serves as a validated, working specification of what your SaaS does.
