System Requirements

On installation, you’ll see the following prompts:

  1. Clone the saasfly repository into the specified folder.
  2. Remove git history
  3. Install dependencies
  4. Generate prisma type

After the prompts, create saasfly will create a folder with your project name and install the required dependencies.

2. Start Saasfly

You should do below lists to run the server.

Set Up The Environment Variables

Enter the saasfly folder, duplicate the .env.example file, rename it to .env.local , and enter your variables.

Terminal window
cd saasfly
cp .env.example .env.local

POSTGRES_URL must in your .env.local file:

# Format Example
POSTGRES_URL="postgres://postgres:[email protected]:5432/saasfly"

Run Build First

Because some basic components are compile-time needed, you should run build first.

Terminal window
bun run build

Run The Development Server

Use bun run to start your web server:

Terminal window
bun run dev:web
@saasfly/nextjs:dev: cache bypass, force executing ad8bea47f156e113
@saasfly/nextjs:dev: $ bun with-env next dev
@saasfly/nextjs:dev: $ dotenv -e ../../.env.local -- next dev
@saasfly/nextjs:dev: ▲ Next.js 14.1.0
@saasfly/nextjs:dev: - Local: http://localhost:3000
@saasfly/nextjs:dev: automatically enabled Fast Refresh for 1 custom loader
@saasfly/nextjs:dev: ✓ Ready in 12.1s

If all goes well, Saasfly should now be serving your project on http://localhost:3000, and you can see the result:

Congratulations! Now you can start coding to build your SaaS.

If you’re new to Saasfly, see the project structure docs for an overview of all the possible files and folders in your application.
