Browser Storage Guardrails SDK
A lightweight JS/TS SDK plus dashboard that enforces safe browser-storage usage (localStorage/sessionStorage/IndexedDB) with quotas, schemas, and auto-fallback behaviors. It prevents QuotaExceededError crashes by wrapping writes, emitting telemetry, and offering drop-in migration utilities from unsafe localStorage patterns to IndexedDB with TTL and eviction policies.
Target customer
Frontend platform/infra leads and engineering managers at SaaS companies running large SPAs where client-side storage misuse can cause widespread user-facing outages.
Problem-solution fit
Teams keep shipping code that treats localStorage as unlimited, leading to hard-to-debug production crashes and user lockouts. The product adds enforceable client-side storage budgets, safer APIs, and visibility into what is being stored (and by whom), turning an outage-prone anti-pattern into an auditable, testable platform capability.
