A YouTube analytics platform co-founded by MrBeast (Jimmy Donaldson) and Chucky Appleby in 2023. Offers deep video and channel insights: views over time, thumbnail/title change tracking, a ranking system comparing a video to the creator\'s previous nine uploads, video comparison, one-click channel analytics, and trending channels. Available as a Chrome extension (100K+ users), Firefox add-on, iOS/Android apps, and a web platform with advanced analytics, creator discovery, and a Business API (Business plan from $249/mo, unlimited credits). Free tier available; Pro is $49.99/mo (US App Store). Note: in June 2025, Viewstats launched an AI thumbnail generator that let users mimic other creators\' styles; after intense backlash from creators (including Jacksepticeye), MrBeast removed the feature within days, acknowledging it \"fundamentally hurts creators,\" and replaced it with a thumbnail designer directory. The platform is now focused on data analytics, not AI generation.
