CLONE — YOU CAN REBUILD THE FEATURE
At its core, ViralSweep provides campaign widgets that accept form submissions, assign referral links, count bonus entries, and draw winners randomly. The frontend interface and database relationships are straightforward to build with Cursor or Lovable. What you actually pay ViralSweep for is not the core software logic, but turnkey legal rule compliance, pre-built ESP webhooks (Klaviyo/Omnisend), and built-in anti-bot mechanisms. If your store only runs standard email-capture giveaways twice a year, paying $199/month is unnecessary overhead.

Why this verdict
ViralSweep charges monthly fees for form widgets, unique referral link attribution, and random winner selection logic. Building a custom Next.js giveaway engine connected to Supabase takes less than a weekend for a competent developer.

The one-shot build prompt
Paste it into your agent of choice. Nothing else needed.
Build a custom, lightweight ecommerce sweepstakes and referral engine using Next.js (App Router), Tailwind CSS, Supabase (Postgres), and Cloudflare Turnstile.
1. DATA MODEL:
- Create table 'campaigns': id (uuid), title (text), slug (text, unique), start_at (timestamp), end_at (timestamp), is_active (boolean).
- Create table 'entrants': id (uuid), campaign_id (fk campaigns), email (text), first_name (text), referral_code (text, unique), referred_by_id (fk entrants, nullable), ip_address (text), entry_count (integer, default 1), created_at (timestamp).
- Add a unique constraint on (campaign_id, email).
2. CORE FUNCTIONALITY:
- Public submission API endpoint ('/api/entry'): Accepts campaign_slug, email, first_name, referral_code (optional), and turnstile_token.
- Verify Cloudflare Turnstile CAPTCHA server-side. Reject if invalid.
- Reject temporary/disposable email domains (check input against a list of common throwaway domains).
- Insert new entrant. Generate a unique 6-character alphanumeric referral_code.
- If a valid referral_code was provided, look up the referrer. Increment referrer's entry_count by 3 and set referred_by_id on the new entrant.
- Return entrant payload with their generated shareable referral URL (e.g., https://store.com/giveaway?ref=CODE).
- Include a serverless cron route ('/api/admin/draw-winner') secured with a secret key. It must select N random winning entries weighted by entry_count using a cryptographically secure method (crypto.getRandomValues), excluding flagged IPs.
- Include an automatic webhook push to Klaviyo API ('/api/klaviyo-sync') on successful entry creation to push the subscriber, their referral link, and total entries as custom profile properties.
3. FRONTEND WIDGET:
- Create an embeddable React component or script tag that renders a sleek modal popup with custom styling.
- Display entry form, live referral link generator upon submission, and copy-to-clipboard referral sharing buttons.
4. OUT OF SCOPE:
- Do not build legal rule generators, social network OAuth API verifications, or complex email design tools.$ each button prefixes agent-specific run instructions · build your own product, never copy proprietary code, trademarks or designs
