Master build prompt for an on-demand (Uber-like) services app

The build prompt for an on-demand app with customer, provider and operator roles: matching, live tracking, payments and ratings.

Built for: Startups building local services marketplaces

On-demand products are really three apps: the customer app, the provider app and the operations dashboard. The matching algorithm, real-time location and the payment/commission flow are the hardest parts of the product.

The prompt defines the request-matching state machine, driver/provider onboarding, live tracking and payouts in a mobile-first architecture.

FAQ

How does the matching algorithm start out?

With simple scoring weighted by distance, availability and rating; the prompt adds data-collection constraints so you can move to a learning model over time.

Mobile app or web?

A single React Native (Expo) codebase is the default; the prompt defines the web operations dashboard separately in Next.js.

Which tools can I paste the generated prompt into?

Claude Code, Cursor, Windsurf, v0, Lovable, Bolt and ChatGPT. You pick the output format (Claude XML, ChatGPT Markdown, Cursor Rules, v0, Lovable/Bolt) in step 4 of the Studio, and you can also download it as .cursorrules or CLAUDE.md.

Is it free?

Yes. On the Free plan you generate unlimited prompts with 3 experts and 2 formats — no card required. 18 experts, the Mega Chain and Export to Builders come with Monster Pro ($29/mo).
