Can I vibe code Fera?

The verdict

YES — VIBE CODE IT

What you pay Fera for is convenience: off-the-shelf theme integration scripts, pre-built review request email workflows, and image optimization CDN hosting. The core logic—storing star ratings, text, and media attached to a Product ID—is trivial database management. What is non-trivial is handling email deliverability at scale, FTC compliance requirements for verified buyer badges, and Google Shopping review feed XML formatting. If you run a custom frontend or modern Shopify stack, an in-house review system avoids recurring fees and widget rendering slowdowns.

The one-shot build prompt

The one-shot build promptbuild it on Lovable
Build a lightweight product review system for an ecommerce store using Next.js (App Router), Supabase (Database + Auth + Storage), and Resend. 

1. DATA MODEL:
- Create a `products` table (id, external_product_id, title).
- Create an `orders` table (id, customer_email, external_order_id, fulfilled_at, review_sent_at).
- Create a `reviews` table (id, product_id, order_id, rating (1-5), author_name, body, verified_buyer boolean, status [pending, approved, rejected], created_at).
- Create a `review_media` table (id, review_id, image_url, media_type).

2. BACKEND & WEBHOOKS:
- Implement API endpoint `/api/webhooks/order-fulfilled` to capture order events and upsert `orders` and `products` tables.
- Set up a cron route `/api/cron/send-review-requests` that queries orders fulfilled exactly 14 days ago where `review_sent_at` is null. Send an email via Resend with a signed JWT link pointing to `/review/submit?token=...`.

3. FRONTEND SUBMISSION & DISPLAY:
- Build `/review/submit` page accepting the signed token, pre-filling customer details, allowing a 1-5 star selection, body text, and S3/R2 direct photo upload via presigned URLs.
- Build a lightweight JS web component or standalone API route `/api/widgets/reviews?product_id=X` returning JSON array of approved reviews and calculated `average_rating` / `total_count`.
- Include standard Schema.org AggregateRating JSON-LD object generator for SEO.

4. FAILURE MODES & OUT OF SCOPE:
- Reject duplicate submissions for the same order_id + product_id combination.
- Sanitize all body text against XSS before database insertion.
- Out of scope: AI sentiment analysis, complex social proof popups, and multi-currency discount generation.

FAQ

+Can I really replace Fera with an AI-generated app?

YES — IT IS A RELATIONAL DB TABLE WITH AN EMBEDDABLE SCRIPT AND TRANSACTIONAL EMAIL. Fera provides straightforward functionality: receiving order webhooks, scheduling a post-purchase email, and serving a JS widget that fetches reviews from a database. Building a custom version takes a weekend using a modern stack like Supabase and Resend, allowing full control over design without monthly caps on email review requests. An MVP takes roughly 1 weekend; matching the product properly is closer to 2-3 months, primarily due to email deliverability edge cases, image CDN setup, and FTC compliance tooling.

+How long does it take to rebuild Fera?

A usable internal version: 1 weekend. A version you would sell or bet a business on: 2-3 months, primarily due to email deliverability edge cases, image CDN setup, and FTC compliance tooling, mostly spent on optimizing js embed footprint so widgets do not degrade core web vitals.

+What do you actually lose by leaving Fera?

Turnkey Google Shopping Rich Snippet XML feed generation Out-of-the-box native theme app extensions for one-click installation Built-in FTC compliance tools for disclosure of incentivized reviews

+Is it legal to build a Fera alternative?

Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
