Creator and commerce decision
Karrito
A competent technical user can build and host a minimal Karrito-like catalog with WhatsApp checkout by adapting an existing MERN e-commerce project; the product's main durable advantages (themes, polish, integrations, onboarding) are reproducible but costly to match.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Karrito alternatives, with the arithmetic →
What a replacement has to do
- Customer opens a mobile-first product catalog → adds items to cart → clicks 'Pedir por WhatsApp' → a formatted order message is generated and sent to the merchant's WhatsApp; merchant views orders in an admin panel and marks status.
What it still won’t have
- Polish and dozens of pre-built premium store themes and design variants
- Built-in integrations (Telegram notifications, Meta Pixel, pre-made webhooks) and turnkey IA tools
- Lifetime plan option and Karrito support/onboarding
- Built-in reviews automation and SEO microformats out of the box
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a mobile-first catalog + WhatsApp-checkout app using a MERN stack (React frontend, Node/Express backend, MongoDB or Postgres, deployed on a VPS or managed service like Render/Vercel + managed DB). In scope: responsive storefront with categories and product pages, product/admin CRUD with authentication, cart UI that generates a pre-filled WhatsApp message from cart contents, admin order list and status updates, simple visit/order analytics, file upload for product images, HTTPS deployment, documentation, error handling, and unit/integration tests for API endpoints. Out of scope: multi-tenant SaaS billing, advanced theme marketplace, native iOS app, advanced AI integrations. Include CI, backup of the DB, basic monitoring, and a small script to seed example products.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
