Unreliable offline web navigation — persist segment cache & replay

Unreliable offline web navigation — persist segment cache & replay targets a $12.0B = 20M web dev teams x $600/year tooling/hosting spend (global web dev tooling + CDN + edge services) total addressable market with medium saturation and a year-over-year growth rate of 18% — web dev tooling and edge compute growth driven by PWAs, edge functions, and mobile-first web.

Key trends driving demand: Edge compute proliferation -- cheaper and more capable edge runtimes (Workers, Functions) enable runtime caching and replay close to users.; Offline-first UX expectation -- users expect native-like behavior on poor networks, driving demand for robust offline navigations.; Framework convergence on RSC/App Router patterns -- standardized server/client component models make generated fallbacks viable across apps.; AI-driven developer tooling -- codegen and testing assist in authoring complex service-worker and caching logic safely and faster..
