ScannerX — engagement analytics for X

See who matters on X in seconds. A post gets 100s of replies and somewhere in there could be a founder, an investor, a journalist, or just someone with a million followers. Finding them means opening dozens of profiles by hand, so you don't, and the moment passes. ScannerX ranks them in one click. Your first 10 analyses are free. PRIVACY FIRST No password, ever. No X API. No automated actions. It cannot follow, reply, repost, or message on your behalf. When you open a post, X's own servers send the engagement data to your browser to draw the page. ScannerX reads what already arrived and sorts it. Nothing is sent to any external server. It all happens in your browser, and you can watch it in the network tab. WHAT IT DOES Engagers — everyone who replied or reposted, ranked by follower count, with a breakdown from the largest accounts to the smallest. Quotes — every quote-tweet, ranked by the quoter's reach, with each quote's own engagement. Posts — any profile's posts sorted by likes, views, or engagement rate, plus median engagement and real engagement rate across their last 25, 50, or 100 posts. Useful whenever you want to know whether an account actually has influence, rather than just a large follower count. Search — advanced X search built with fields instead of memorised syntax. Everything exports to CSV. WHO IT'S FOR Creators deciding who is worth replying to. Founders checking whether anyone notable saw a launch. Marketers evaluating an account before a collaboration. Researchers and journalists working out who is driving a conversation. Or anyone who simply wants to understand who is interacting with them. LIMITATIONS X made likes private in 2024, so no tool can show who liked a post. ScannerX works with what remains public: replies, reposts, and quote-tweets. Reposts and quote lists are capped by X at roughly the most recent 100 accounts. LICENCE The first 10 analyses are free. After that ScannerX requires a one-time licence, available at scannerx.app. Not a subscription.
