Open Saas pricing
Pricing model: Freemium
Open SaaS itself is 100% free and open-source to use and distribute. The template includes a default pricing structure with three plans you can configure: Hobby subscription plan at $9.99/month, Pro subscription plan at $19.99/month (most popular), and a credits10 one-time purchase plan.

Frequently asked questions about Open Saas
What is Open SaaS?
Open SaaS is a free, open-source, full-stack SaaS starter kit for React + NodeJS + Prisma, built for the AI era and powered by Wasp. It comes with everything a SaaS needs out of the box: authentication, Stripe/Polar.sh/Lemon Squeezy payments, admin dashboard, analytics, OpenAI integration, file uploads, email sending, blog, E2E tests, and one-command deployment.
Is Open SaaS really free?
Yes, Open SaaS is 100% open-source and completely free to use and distribute. The template itself costs nothing. You only pay for your hosting provider, payment processor fees, and any third-party services you use like SendGrid for email or AWS S3 for file storage.
What technologies does Open SaaS use?
Open SaaS is built on Wasp (full-stack React/NodeJS/Prisma framework), Astro for the blog/docs, Stripe or Lemon Squeezy for payments, Plausible or Google Analytics, OpenAI API for AI features, AWS S3 for file uploads, SendGrid/MailGun/SMTP for email, TailwindCSS for styling, TailAdmin for admin dashboard components, and Playwright for E2E tests.
How do I install Open SaaS?
First install Wasp on macOS, Linux, or Windows with WSL by running: curl -sSL https://get.wasp-lang.dev/installer.sh | sh. Then create a new SaaS app with: wasp new -t saas. This creates a clean copy of the Open SaaS template in a new directory where you can start building immediately.
Where can I deploy Open SaaS?
You can deploy Open SaaS anywhere with no vendor lock-in since you own all your code. The easiest option is one-command deploy to Fly.io via the Wasp CLI. It also works on Railway, Netlify, and other providers. The template includes a CI pipeline with GitHub Actions for automated testing and deployment.
What payment providers are supported?
Open SaaS supports Stripe, Polar.sh, and Lemon Squeezy as payment providers. Checkout and webhooks are pre-configured for all three. You just choose your provider and plug in your product/price IDs in the .env.server file. Payment provider expansion including Paddle and regional-friendly options is on the roadmap.
Does Open SaaS have authentication built-in?
Yes, Open SaaS comes with pre-configured full-stack authentication that you own. It includes email verification plus social authentication with Google and GitHub login. The auth is built with Wasp's abstractions and requires just a few lines of code to set up. You have full control over the authentication system.
Is there an admin dashboard?
Yes, Open SaaS includes a built-in admin dashboard with graphs, tables, and analytics. Admin users can access the user table to view and search for users, and edit or update information manually. The dashboard uses TailAdmin components for TailwindCSS and integrates with Plausible or Google Analytics.
How do I add more subscription plans?
You add more plans by creating additional products and price IDs in your Stripe dashboard, then updating the environment variables in your .env.server file and the relevant code in your app. By default, the template has hobby and pro subscription plans plus a credits10 one-time purchase plan that you can customize.
What AI features are included?
Open SaaS includes OpenAI API integration out of the box with a simple example. It's designed as an AI-first developer experience with Wasp's abstractions, opinionated defaults, and custom agent rules, skills, and tools for AI-assisted coding tools like Cursor, VSCode + Copilot, or Claude. The roadmap includes expanding AI workflows with Vercel's AI SDK and Cursor/Claude prompt presets.
