UNIFIED SYNC BETWEEN WEB AND MOBILE APPS

Fast, Always-On Web Apps With Couchbase Lite for JavaScript

Deliver consistent, offline-ready web experiences with universal sync across cloud, mobile, and web.

CHALLENGE + IMPACT

The internet doesn't work everywhere

Modern web applications must work everywhere – even in elevators, subways, and remote locations. When apps depend entirely on internet connectivity, users lose access, data gets out of sync, and performance lags, leading to frustration and churn.

Apps stop working without internet

Users expect uninterrupted access, even in offline conditions.

Data gets out of sync

Switching between web and mobile versions of an app often causes inconsistency.

High server and network costs

Overreliance on cloud APIs increases latency and egress charges.

Networks limit reliability for web apps

Web apps built on cloud-only architectures fail when networks slow or disappear. Caching strategies help temporarily, but without a full-featured embedded database and enterprise-grade sync, data integrity and user experience break down.

Browser storage lacks built-in sync and conflict handling
Data loss risks increase when the browser crashes or when switching devices
Performance drops and costs rise from repeated cloud API calls
Browser storage provides only basic access, with no advanced query or encryption support

Use cases

Where does Couchbase Lite's embedded database help?

Applications designed to function without constant connectivity and to sync data seamlessly whenever they go online. They’re common in low-connectivity environments like field operations and PWAs.

Apps that allow multiple users to work on shared data in real time, such as note-taking or document editing tools, where conflict resolution and sync consistency are key.

Solutions that continuously update shared information, like live dashboards or flight arrival boards. These displays require low-latency data delivery and instant synchronization.

Applications that provide a consistent experience across multiple device types, including mobile, web, and desktop. They must sync data seamlessly between platforms to unify the user experience.
