CHALLENGE + IMPACT

When the internet drops, your business shouldn’t

Web apps run your business – bookings, transactions, customer experiences. When networks slow or drop, users abandon, transactions fail, and revenue stops. Every minute offline costs money and trust.

  • Downtime costs revenue and trust

    Networks fail in dead zones, on cellular, mid-transaction. When apps stall, users churn and revenue stops.

  • Web and mobile drift out of sync

    Users moving between web and mobile see stale or conflicting data without a unified sync layer.

  • Latency drives users away

    Every cloud API roundtrip adds latency. Spinning wheels and “please wait” alerts kill conversion.

Cloud-only architectures can’t survive outages

Web apps on cloud-only architectures stall when networks slow or fail. Browser caching is a stopgap. Without a real embedded database and enterprise-grade sync, data integrity and UX break down.

  • Browser storage lacks built-in sync, conflict resolution, and governance
  • Data loss risk when browsers crash or users switch devices
  • Repeated cloud API calls add latency and egress costs
  • Browser storage is not a database! No SQL queries, search, or encryption

Products

An embedded database in your browser, with sync

Couchbase Lite for JavaScript embeds a full NoSQL database directly in the browser, so web apps read and write at memory speed and keep working when the network slows or drops. Paired with Couchbase Sync Gateway or hosted App Services, it delivers unified, bi-directional sync from cloud to mobile to web – one platform, zero downtime, one developer experience across every client.
