How to Use Open SaaS
Install Prerequisites: Make sure you have Node.js and NPM installed on your machine and available in PATH to use Wasp
Create New Project: From your desired directory, run 'wasp new' command and select option [3] saas from the templates list after entering your project name
Start Development Server: The app will run on http://localhost:3000 (client) and http://localhost:3001 (server). The blog/docs will typically run on https://localhost:4321
Configure Authentication: By default it uses email authentication with a Dummy provider for development. For production, configure a real email provider like SendGrid in the main.wasp file
Set Up Payment Processing: Add your Stripe API keys and configure the payment processor in src/payment/paymentProcessor.ts. Create products/prices in your Stripe dashboard
Configure Additional Services: Set up other services like OpenAI, AWS S3, Analytics etc by adding their API keys to your environment variables as needed

Test Your App: Run the included E2E tests with Playwright and verify all features are working as expected
Deploy: Deploy your SaaS app using Wasp's one-command deploy to Fly.io, or manually deploy to any provider. Deploy the blog separately to services like Netlify
