FullStory

FullStory helps companies "Perfect their Digital Experience." We provide privacy-focused session replay and analytics and integrate with other tools such as CRM, ticketing systems, and error trackers. Our customers' engineers love using FullStory because it makes it so much easier to understand and reproduce bugs. Our code is mainly in Go (Golang) and TypeScript, but there are a lot of other interesting bits, including a small amount of Rust. FullStory has been described as "a startup for people with kids".
