LogRocket

LogRocket is a frontend application monitoring platform founded in 2016 by Matthew Roggeritore, headquartered in Boston, providing session replay, error tracking, performance monitoring, and product analytics specifically designed for JavaScript web applications and React Native mobile apps, combining the capabilities of Sentry, Hotjar, and Google Analytics into a unified platform that helps engineering teams reproduce bugs, understand user behavior, and optimize application performance, adopted by companies including Nasdaq, Conde Nast, NBCUniversal, and Stitch Fix. The session replay feature captures pixel-perfect recordings of user sessions including DOM changes, network requests, console logs, JavaScript errors, Redux state changes, and user interactions, replayable with full fidelity to reproduce exact issues as experienced by users, enabling developers to debug problems that cannot be reproduced locally by watching the exact sequence of events leading to errors. The Redux and state management integration logs state changes alongside session replays, enabling developers to inspect the application state at any point during a user session, understanding what data was loaded, how the state mutated, and which actions triggered unexpected behavior, with support for Redux, MobX, Zustand, Vuex, Pinia, and Apollo Client. The error tracking captures JavaScript exceptions, React render errors, network failures, and unhandled promise rejections with full stack traces, source maps, and contextual data, automatically grouping similar errors and correlating them with user session replays for visual reproduction. The performance monitoring tracks Core Web Vitals, page load times, API response times, and render performance. The analytics features include funnels, retention, and custom events. Designed for frontend developers, product engineers, and support teams.
