ProCompare — Compare Across Stores

Shop with confidence. ProCompare adds a quality panel to product pages that blends a product's rating, review count and sales into a single 0–100 verdict — using confidence-adjusted math, so a high rating from only a few reviews doesn't mislead you. What you get: • A clear quality verdict on every supported product page (price, rating, reviews, sold, score) • One click to compare the same product on other supported stores • Right-click any image on the web to find that product elsewhere • A draggable panel with light and dark themes • Free — no account, no tracking, no ads ProCompare is private by design: it has no servers and collects no personal data. It reads product details locally to show the panel and remembers only your theme and panel position — on your device.
