State Storage Policy SDK
A frontend SDK that automatically decides whether state should live in the URL, local storage, session storage, or remote storage based on size, sensitivity, and shareability. This turns scattered architecture advice into a productized decision engine with safe defaults.
Why this matters
You often know there is a problem only after a workflow starts failing in production. A team chooses URL parameters for convenience, then later discovers the state is too large, too sensitive, or impossible to share properly. Another team uses browser storage and then realizes handoff between users does not work. Without a clear policy, every app invents its own rules, and those rules usually depend on whoever has the most experience in the room. What you want is a reliable layer that evaluates state size, sharing needs, and risk level up front, then routes data to the right place before the architecture becomes brittle.
- · Built for Frontend teams and design-system/platform engineers responsible for shared app infrastructure across many internal tools or customer-facing workflows..
- · Most likely monetization: SaaS subscription.

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Developers may treat this as architecture advice rather than a product worth paying for
- 2False positives or overly strict policies could frustrate adoption
- 3Open-source alternatives may replicate core routing logic quickly
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion repeatedly showed confusion about which storage method fits which use case, with many alternative patterns suggested and no clear standard. Shareability, sensitivity, and payload size were the main decision factors. This creates room for a policy-driven tool that turns fragmented best practices into repeatable implementation defaults.
