Bounded local-span request history with deduped fetch insights for frontend devs

Bounded local-span request history with deduped fetch insights for frontend devs targets a $18.0B = 150,000 cloud-native mid/enterprise organizations x $120k annual observability stack spend total addressable market with medium saturation and a year-over-year growth rate of 18% (APM/observability growth driven by cloud-native adoption and frontend observability needs).

Key trends driving demand: Frontend complexity -- Single-page apps, streaming and edge rendering increase the need for request-level visibility on the client.; Shift-left observability -- Developers expect production-like diagnostics locally and during HMR, increasing demand for dev-focused telemetry.; Open telemetry standards -- OTel adoption simplifies capturing spans, enabling rapid integration across tools and vendors.; AI-assisted debugging -- ML models can convert raw spans into human-friendly root-cause summaries, raising value of preserved raw spans..
