1. Foresyte — Best Free AI Demand Forecasting Platform
Pricing: Free forever — every feature included | Account opening: No credit card required
Foresyte is the only free, AI-powered, archetype-intelligent demand forecasting platform on the market — built specifically for SMB e-commerce brands selling across multiple marketplaces. Its standout innovation is archetype-based model selection: every product is automatically classified into one of five behavioral archetypes (Holiday Heroes, Volatile Seasonals, Growth Rockets, Steady Subscription, New/Sparse), and each archetype receives a purpose-built ML model.
This multi-model approach delivers 35% wMAPE — roughly half the error rate of the 50-70% industry average. Every forecast comes with a confidence score (0-100) and P80 prediction intervals, so you know exactly how much to trust each number.
The built-in backtesting with rolling-origin validation lets you verify accuracy before committing to inventory purchases. An exception-based workflow surfaces only the ~20 out of 2,000 products that need human review, saving hours per week. Three-tier parameter tuning (global, segment, per-product) gives you control without complexity.
Strengths: Archetype intelligence, multi-model accuracy, backtesting, confidence scoring, 5-marketplace support, free forever.
Limitations: PO generation via API only (not built-in), no BOM/raw materials tracking.
Best for: Small-to-medium e-commerce brands selling on 2+ marketplaces who want free, accurate forecasting with full transparency.
2. Prediko — Best for Shopify-Only Brands
Pricing: From $49/month | Trial: Two weeks
Prediko is a Shopify-native demand planning tool that combines AI forecasting with purchase order management and raw materials/BOM tracking. Its tight Shopify integration makes setup fast, and the PO workflow from forecast to supplier order is well designed.
Strengths: Shopify-native experience, PO management, BOM/raw materials tracking, accessible pricing.
Limitations: Shopify-only (no Amazon, Walmart, etc.), no backtesting, no archetype intelligence, no confidence scoring.
Best for: Small to mid-size Shopify-only brands that need forecasting + PO management in one tool.
