Monsa vs BigSpy (2026): Broad Coverage vs AI-Powered Intelligence
Quick Verdict
BigSpy has the broadest platform coverage (9 ad networks) and the cheapest entry point. But its TikTok data is locked behind enterprise pricing, and it has no AI scoring, no alerts, no Shopify monitoring. Monsa wins on actionable intelligence for dropshippers.
What Is BigSpy?
BigSpy (bigspy.com) is a multi-platform ad intelligence tool that claims 1B+ ads indexed across 9 networks: Facebook, Instagram, Twitter/X, Pinterest, Yahoo, TikTok, YouTube, AdMob, and Unity. It's positioned as the broadest-coverage option in the ad spy category.
- Pricing: Free (5 queries/day, Facebook only) → Basic $9/mo (20 queries/day, FB+Instagram) → Pro $99/mo (unlimited queries + Twitter/Pinterest/Yahoo) → VIP Enterprise (custom pricing — required for TikTok, YouTube, AdMob)
- TikTok access: Locked behind VIP Enterprise at custom (typically $300+/mo) pricing — not available on $9 or $99 plans
- Database: 1B+ ads, 500,000 new ads added daily
- Limitations: No AI features, no Shopify competitor spy, no email alerts, TikTok behind enterprise paywall
The TikTok Bait-and-Switch
BigSpy prominently features TikTok in its marketing, but TikTok access requires VIP Enterprise pricing (custom, typically $300+/mo). The $9 Basic and $99 Pro plans cover Facebook, Instagram, Twitter, Pinterest, and Yahoo — but not TikTok. This is misleading for dropshippers who sign up expecting TikTok coverage.
What Is Monsa?
Monsa is a focused e-commerce intelligence platform built around three features that BigSpy doesn't offer at any price point:
- AI Score (0–100): Every product gets a quantified virality score from TikTok Shop + ad signals. BigSpy shows you raw ads — Monsa tells you which products to act on.
- Trend Alerts: Automated daily email digest at 7 AM with new high-scoring products matching your keywords. BigSpy has no notification system.
- Shopify Competitor Spy: Automated monitoring of competitor Shopify catalogs with email alerts on new product launches. BigSpy doesn't track Shopify stores.
- TikTok Shop US data: Real purchase signals from TikTok Shop, not just ad impressions. Available from Monsa Scale (€79/mo) — still significantly cheaper than BigSpy's enterprise-only TikTok ($300+/mo).
Feature Comparison
| Feature | Monsa | BigSpy |
|---|
| AI Virality Score (0–100) | ✅ Yes | ❌ No |
| Daily Trend Alert Emails | ✅ Yes | ❌ No |
| Automated Shopify Competitor Spy | ✅ Yes | ❌ No |
| TikTok Shop US Product Data | ✅ Scale (€79/mo) | ❌ Enterprise only ($300+/mo) |
| Facebook / Instagram Ads | ✅ Yes | ✅ Yes (all plans) |
| Twitter / Pinterest Ads | ❌ No | ⚠️ Pro plan ($99/mo) |
| YouTube / AdMob Ads | ❌ No | ⚠️ Enterprise only |
| Total Ad Database Size | — | 1B+ ads, 9 networks |
| Free Forever Plan | ✅ Real free tier | ⚠️ 5 queries/day, FB only |
| Entry Price for Meaningful Use | €29/mo (Pro) | $99/mo (Pro) for serious research |
Where BigSpy Wins
- Broadest ad network coverage: 9 platforms including YouTube, AdMob, and Unity — no other tool in this category covers as many networks. Useful for agencies running campaigns across multiple channels.
- 1B+ ad database: Largest raw ad database of any tool reviewed — 500,000 new ads added daily across all platforms.
- Cheapest entry: $9/month for Facebook + Instagram is genuinely the cheapest meaningful plan in the ad spy category. Free forever plan with 5 daily queries.
Where Monsa Wins
- AI Score — BigSpy has nothing equivalent: BigSpy presents raw ad data. Monsa ranks every product by virality probability. For dropshippers, the difference is hours of manual filtering vs. instant prioritization.
- TikTok Shop data — at a fraction of BigSpy's enterprise price: Monsa's Scale plan (€79/mo) includes TikTok Shop US product data; global TikTok Shop is on VIP+ (€149/mo). BigSpy's TikTok access requires enterprise pricing (typically $300+/mo). Even at VIP+, Monsa is meaningfully cheaper for TikTok access.
- Automated Trend Alerts: BigSpy has no notification system. Monsa sends you winning products every morning without you lifting a finger.
- Shopify Competitor Spy: BigSpy doesn't monitor Shopify catalogs. Monsa alerts you when any competitor adds a new product.
- Actionable intelligence vs. raw browsing: BigSpy's strength is volume of ads. Monsa's strength is telling you which underlying products are worth pursuing — a fundamentally more useful output for dropshippers.
AI Intelligence. Lower Price.
AI Score, daily alerts, and Shopify competitor spy from €29/mo. TikTok Shop US data from Scale (€79/mo) — still cheaper than BigSpy's enterprise TikTok tier.

Which Should You Choose?
- Choose BigSpy if: You're an agency or advertiser who runs campaigns across many platforms including Twitter, Pinterest, and YouTube and need broad cross-platform creative research at a low entry cost. The $9 Basic is a reasonable choice for early-stage Facebook research.
- Choose Monsa if: You're a dropshipper who wants TikTok Shop intelligence, an AI virality score, automated daily alerts, and Shopify competitor monitoring — without paying enterprise pricing for basic TikTok access.
Final Verdict
BigSpy and Monsa are built on fundamentally different philosophies. BigSpy maximizes breadth — the most platforms, the most raw ads, the cheapest entry. Monsa maximizes actionability — the AI Score, the automated alerts, the product-level intelligence that drives decisions.
For dropshippers specifically, Monsa wins. BigSpy's breadth is less relevant when your primary channels are Facebook and TikTok — and TikTok on BigSpy requires an enterprise plan costing $300+/mo. Monsa's Scale plan (€79/mo) includes TikTok Shop US data, and even the €29/mo Pro plan covers AI scoring, daily alerts, and Shopify competitor monitoring that BigSpy doesn't offer at any price point.
More Intelligence. Lower Price.
