ExtWise

ExtWise is a Chrome Extension Intelligence Platform that helps developers, security teams, and growth teams make sense of the entire Chrome Web Store. It indexes over 281,000 extensions and applies AI-powered analysis to surface insights that are otherwise scattered across reviews, listings, manifests, and changelogs. For developers, ExtWise provides competitor analysis, feature comparison matrices, keyword and ASO (App Store Optimization) research, and market positioning data. For security teams, it offers permission auditing, risk scoring, malware detection alerts, and data flow mapping so you can vet extensions before they reach your users. For growth teams, it tracks category-level market trends, user migration patterns, and real-time changes to help identify untapped opportunities. The platform tracks 18 Chrome Web Store categories (Productivity being the largest at ~135K extensions), reports an average rating of 4.4 stars across all extensions, and monitors Manifest V3 compliance (~89%). ExtWise also exposes a Snapshot API for programmatic access to extension metadata, manifests, permissions, and risk assessment fields.
