Example Prompts

Try these in Cursor Agent mode, Claude Code, or any MCP-enabled AI editor:

Create & Deploy:

• "Create a new SaaS app called my-dashboard"
• "Deploy this project to production"
• "Deploy and submit to the Varity App Store for $19/month"

Manage & Debug:

• "Show my deployments"
• "Get the build logs for my last deployment"
• "Why did my deployment fail?"

Migrate from Vercel:

• "Migrate my Vercel app at github.com/me/my-app to Varity"
• "Preview what changes the migration will make"

Docs & Pricing:

• "Search Varity docs for database setup"
• "How much would it cost to host a SaaS app with 5,000 users on Varity?"
• "Compare Varity vs AWS costs for my app"

End-to-End Workflow

From empty folder to deployed app, all from natural language:

You: "Create a new SaaS app called analytics-pro"
AI:  Created analytics-pro with auth, database, dashboard, landing page

You: "Deploy it to production"
AI:  Deployed! Live at https://analytics-pro.varity.app

You: "Submit to the App Store for $29/month"
AI:  Submitted. You earn $26.10/month per user (90% revenue split)
