Twilio Sync
The easy way to build in-app collaboration and continuous experiences across devices
Real-time infrastructure
Twilio maintains millisecond-level state synchronization, so you can focus on building features for customers.

  • Proven at scale

    Grow your app usage with confidence. Sync is the real-time engine behind Twilio Programmable Chat, which handles chat messages for some of the world’s largest enterprises.

  • Persistent state in the cloud

    Save crucial development time. Twilio persists state in the cloud and synchronizes published changes to subscribed devices, so you don’t have to build your own state management.

  • Cross-platform

    Allow users to pick up on their laptop where they left off on their iPhone. Mobile and web SDKs make it easy to manage complex state transitions with a few lines of code.

Intuitive API
Ship faster with a purpose-built API for state synchronization instead of designing from scratch and wrestling with complex state logic.

  • Purpose-built objects

    Real-time features like presence and screen-sharing are easy to build with objects like documents, lists, and maps.

  • Helper libraries & quickstarts in 6 server-side languages

    Build real-time capabilities into your app in the language you already use with helper libraries available from Twilio and its community.

  • Conflict resolution

    Let users collaborate and co-edit in your app even if they are making simultaneous updates. Twilio implements optimistic concurrency control (OCC) in the REST API and SDKs for managing and resolving differences in state between users.

  • Local Sync

    Gracefully handle devices going offline. Sync maintains state locally and automatically re-synchronizes objects once connectivity is restored.

Security & monitoring
Protect your app with data controls and operational visibility.

  • Access Control

    Keep data private between users. Twilio offers fine-grained access control for each individual object and endpoint, so you can define which users have access to what information.

  • Webhooks

    Build custom workflows with real-time visibility into state changes. Webhooks show every event fired and allow you to build custom interactions with other products.

  • Data retention policies

    Only keep the data that you want, for as long as you need it. Sync lets you specify when and how state data is deleted with configurable time-to-live settings for objects.

The Twilio advantage

  • Communicate reliably

    Experience a 99.95% uptime SLA made possible with automated failover and zero maintenance windows.

  • Operate at scale

    Extend the same app you write once to new markets with configurable features for localization and compliance.

  • Many channels

    Use the same platform you know for voice, SMS, video, chat, two-factor authentication, and more.

  • No shenanigans

    Get to market faster with pay-as-you-go pricing, free support, and the freedom to scale up or down without contracts.
