Can I vibe code Vitals?

Q: Can I really replace Vitals with an AI-generated app?

YES — A COLLECTION OF TRIVIAL JS WIDGETS BUNDLED TOGETHER. Vitals consolidates dozens of simple frontend tools—sticky buttons, countdown timers, star ratings, and popups—into a single monthly bill. Building individual widgets using native Shopify theme code or an AI coding agent takes hours, as the underlying logic is standard web development. However, attempting to replicate all 40+ widgets is unnecessary bloat; you only need to build the 3-5 widgets your store actually uses. An MVP takes roughly 1 week; matching the product properly is closer to 3-6 months, due to the volume of 40+ separate micro-widgets.

Q: How long does it take to rebuild Vitals?

A usable internal version: 1 week. A version you would sell or bet a business on: 3-6 months, due to the volume of 40+ separate micro-widgets, mostly spent on injecting lightweight javascript widgets without worsening store core web vitals.

Q: What do you actually lose by leaving Vitals?

Unified admin interface for configuring 40 distinct marketing widgets Library of pre-built UI templates and styling presets Automated email review request scheduling and delivery system

Q: Is it legal to build a Vitals alternative?

The verdict

YES — VIBE CODE IT

You pay Vitals for script aggregation and convenience rather than proprietary technology. Rebuilding core features like sticky add-to-cart, basic product reviews stored in native Shopify metafields, volume pricing via Shopify Functions, and stock countdown timers is straightforward for modern LLMs. The hard part is not the technical difficulty of any single widget, but recreating dozens of administrative control panels if you use the entire suite. Most merchants only utilize a fraction of the bundle, making a targeted self-built replacement faster and better for site speed.

The one-shot build prompt

The one-shot build promptbuild it on Lovable

Build a lightweight Shopify custom app using Remix, Shopify App Bridge, Prisma, and Theme App Extensions to replace core Vitals functionality (Product Reviews, Sticky Add-To-Cart, and Stock Urgency Timers).

1. ARCHITECTURE & TECH STACK:
- Stack: Shopify Remix App Template, Prisma ORM, SQLite/PostgreSQL, TailwindCSS.
- Distribution: Embedded app admin built with Shopify Polaris.
- Frontend Injection: Shopify Theme App Extensions (App Blocks and App Snippets) written in Liquid and Vanilla Web Components.

2. CORE MODULES TO IMPLEMENT:
Module A: Product Reviews
- Admin UI: View, approve, delete, and manually create reviews. Export/Import reviews via CSV.
- Public API: Endpoint to submit reviews with fields (product_id, rating, author_name, email, title, body).
- Frontend App Block: Renders star rating summary on product page and a review list with a submission modal. Save aggregate rating into Shopify Product Metafields (`reviews.rating` and `reviews.rating_count`).

Module B: Sticky Add-to-Cart
- Frontend App Snippet: Floating bar visible only when the main 'Add to Cart' button scrolls out of view. Displays product thumbnail, title, price, variant selector, and an 'Add to Cart' button calling the Shopify AJAX Cart API (`/cart/add.js`).

Module C: Urgency Stock Counter
- Admin UI: Toggle urgency timer on/off, set threshold (e.g., show warning when stock < 10).
- Frontend App Block: Checks item inventory level via Shopify Storefront API or liquid context and renders a dynamic scarcity message (e.g., 'Only 4 items left in stock').

3. DATABASE SCHEMA (Prisma):
- Store (id, shopifyDomain, accessToken)
- Review (id, storeId, productId, authorName, email, rating, title, body, status, createdAt)
- WidgetSettings (id, storeId, stickyAtcEnabled, stockThreshold, accentColor)

4. PERFORMANCE CONSTRAINTS:
- Storefront JS bundle size must be under 15KB total.
- Zero external framework dependencies on the storefront (Vanilla JS or Web Components only).
- Must not block page render or affect LCP/CLS metrics.
