Fullstory Tech Stack

Session replay and behavioral analytics platform for enterprise customer experience

Software Development Atlanta, Georgia 501–1,000 employees Founded 2014 Privately Held

Fullstory operates a behavioral data platform capturing session replay, heatmaps, and user journey analysis for enterprise digital products. The tech stack reveals a heavy cross-platform mobile focus—iOS, Android, React Native, Flutter, Xamarin, and Cordova all appear in active development and adoption—paired with backend services in Go and Rust. This mobile-first engineering direction, combined with pain points around SDK stability in consumer apps and Xcode developer experience, suggests Fullstory is expanding its core session-replay product into mobile-first use cases, a shift away from web-centric analytics.
