Blind spots in frontend monitoring can occur when managing complex modern applications due to browser and device variability, intricate user journeys with multiple touchpoints, and ephemeral frontend components. Datadog's digital experience monitoring products, including Synthetic Monitoring, RUM's Session Replay, and Error Tracking, enable catching problems before they affect users, accelerating debugging, and optimizing frontend testing and debugging. By using these products, companies can reduce friction in testing and debugging, ship high-quality features faster, and quickly address issues impacting users.
