You've decided to build a SaaS app with the Open SaaS template. Great choice!

This template is:

1. fully open-source
2. completely free to use and distribute
3. comes with a ton of features out of the box!
4. ready to work with your favorite AI coding tool or agent (Claude Code, Cursor, Codex, OpenCode, etc.)

🧑‍💻 Check it out in action here: OpenSaaS.sh 📚 Check out the Docs here: Open SaaS Docs

The template itself is built on top of some very powerful tools and frameworks, including:

• 🐝 Wasp - a full-stack React, NodeJS, Prisma framework with superpowers
• 🚀 Astro - Astro's lightweight "Starlight" template for documentation and blog
• 💸 Stripe, Polar.sh, or Lemon Squeezy - for products and payments
• 💅 ShadCN UI - for components & styling (plus admin dashboard!)
• 🤖 AI-Ready - Custom Plugins, Skills, & Rules for AI-assisted coding with Claude Code, Cursor, or your favorite AI-assisted coding tool
• 📈 Plausible or Google Analytics
• 🤖 OpenAI - OpenAI API w/ function calling example
• 📦 AWS S3 - for file uploads
• 📧 SendGrid, MailGun, or SMTP - for email sending
• 🧪 Playwright - end-to-end tests with Playwright

Because we're using Wasp as the full-stack framework, we can leverage a lot of its features to build our SaaS in record time, including:

• 🔐 Full-stack Authentication - Email verified + social Auth in a few lines of code.
• ⛑ End-to-end Type Safety - Type your backend functions and get inferred types on the front-end automatically, without the need to install or configure any third-party libraries. Oh, and type-safe Links, too!
• 🤖 Jobs - Run cron jobs in the background or set up queues simply by defining a function in the config file.
• 🚀 One-command Deploy - Easily deploy your DB, Server, & Client with one commaned to Railway or Fly.io via the CLI. Or deploy manually to any other hosting serivce of your choice.

You also get access to Wasp's diverse, helpful community if you get stuck or need help.

First, to install the latest version of Wasp on macOS, Linux, or Windows with WSL, run the following command:

npm i -g @wasp.sh/wasp-cli

Then, create a new SaaS app with the following command:

wasp new -t saas

This will create a clean copy of the Open SaaS template into a new directory, and you can start building your SaaS app right away!

For everything you need to know about getting started and using this template, check out the Open SaaS Docs.

We've documented everything in great detail, including installation instructions, pulling updates to the template, guides for integrating services, SEO, deployment, and more. 🚀

This repository includes comprehensive code quality tooling to help maintain code standards:

Prettier is configured for automatic code formatting across all JavaScript, TypeScript, and other supported files.

# Check if files are formatted correctly
npm run prettier:check

# Automatically format all files
npm run prettier:format

ESLint is configured with TypeScript and React support to catch potential bugs and enforce code quality standards.

# Run ESLint to check for issues
npm run lint

# Automatically fix fixable issues
npm run lint:fix

The ESLint configuration includes:

• TypeScript support with @typescript-eslint
• React and React Hooks linting
• Sensible defaults tuned for a SaaS application
• Automatic support for CommonJS (.cjs), ES Modules (.mjs), and TypeScript files

Both Prettier and ESLint checks are automatically run in CI/CD pipelines to ensure code quality.

For information about other development tools used to maintain derived projects (like opensaas.sh and template-test), see tools/README.md.

Note that we've tried to get as many of the core features of a SaaS app into this template as possible, but there still might be some missing features or functionality.

We could always use some help tying up loose ends: contributions are welcome! Check out CONTRIBUTING.md for more details.
