A request may be received to debug a web page from a client computing device. An origin response may be obtained for the request from a content server. Child fragment calls may be identified that are in a downstream tier using the origin response. Debugging information may be extracted from the child fragment calls. The debugging information may be aggregated from the child fragment calls. The aggregated debugging information may be parsed for output on a display device. ## Claims ### Claim 1 A system for automated multi-tier debug information collection comprising: at least one processor;
