Local-first paper trading vs online simulators: where the difference actually matters.

Many simulators look similar at first glance. The deeper difference is where the trading record lives after each action.

That affects privacy, recovery, setup effort, and the kind of relationship you enter before the first practice trade.

Once you frame the comparison that way, the split is clear: hosted simulators depend on a backend, while local-first simulators keep the normal practice loop in the browser and on the device.

A local-first simulator keeps the normal practice record in the browser.

In ZEROHUE, lightweight preferences stay in browser storage, while orders, transactions, and saved market history live in IndexedDB.

The privacy gain comes from keeping normal practice data on the device by default, not from magic technology.

Hosted simulators usually start with signup because an online account stores saved trades, settings, and recovery options.

That makes sync, recovery, and collaboration easier.

The tradeoff is simple: the platform, not your browser, holds the main trading record.

Local-first design is stronger when privacy, easy setup, and device-bound control matter more than cross-device continuity.

Online simulators are stronger when remote access, shared identity, and centralized recovery matter most.

The right choice depends on what you want to optimize for.

ZEROHUE is built as a practice tool first, so you can start without signup and keep the routine state on the device in practice mode.

That matches the product boundary. ZEROHUE is not a broker, exchange, or wallet.

For normal practice, keeping the main trading record local is the simpler design. Ranked competitions are the exception: competition records are kept on the server so rankings and settlement stay consistent for everyone in the event.
