localStorage but more |

For developers who love localStorage (but wish it was better).

localStorage is great—until you need persistence (like testing on a different machine!). NLS is the same simple API, backed by the cloud, with localStorage as automatic fallback.

Free tier includes 10 apps, 100MB storage. No credit card required.

// Replace localStorage with NLS
const nls = new NLS({
  appKey: 'your-app-key'
});

// Set data (syncs to cloud)
await nls.set('user:preferences', {
  theme: 'dark',
  language: 'en'
});

// Get data (from any device)
const prefs = await nls.get('user:preferences');

localStorage is great. Here's when you need more.

Honest comparison - use what fits your needs

localStorage Firebase Redis + API NLS
Setup time 0 min ~30 min ~2 hours ~2 min
Cross-device sync
Survives browser clear
Backend required No Optional Yes No
SDK complexity None High DIY Minimal
Vendor lock-in None High Low Low (export anytime)
Free tier Varies by browser 1GB Varies 100MB

TL;DR: localStorage is perfect for ephemeral client-side data. Add NLS when you need it to survive browser clears, sync across devices, or exceed 5MB.

FAQ

All data is encrypted in transit (TLS 1.3). Data at rest is stored in isolated application namespaces.

We're committed to GDPR and Australian Privacy Act compliance. We provide data export, deletion rights, specific retention periods, and clear legal bases for processing. Data is stored in secure, isolated environments. See our Privacy Policy for full details.

You'll get a 402 response on write operations. Reads still work. You can either delete data, upgrade, or pay for overage. We won't delete your data without warning.

Yes. Full JSON export available anytime from the dashboard. No lock-in, no export fees. Your data is yours.

Typically under 50ms for reads, under 100ms for writes. Our SDK writes to both NLS and localStorage simultaneously - if NLS is ever unavailable, your app falls back to localStorage automatically.

Yes. 60 reads/min and 30 writes/min per app key on free tier. Higher limits on paid plans. Headers tell you your current usage.

The SDK writes to both NLS and localStorage simultaneously. If our servers are unreachable, your app continues working with localStorage as the fallback - no data loss, no downtime. When we're back, it syncs automatically.

Just like localStorage, but WAY better.

Same API you know and love. Now with persistence, sync, and no size limits.
