Twilio has announced the public beta launch of Twilio Sync, a real-time state management system in the cloud. With Sync, developers can now synchronize web and mobile apps with a single authoritative state in the cloud, without having to build websocket connectivity infrastructure. This allows developers to focus on building features for their customers instead of managing complex connections. Sync is designed to work with Twilio Programmable Voice, Video, Chat, or other Twilio products to provide context-rich real-time communications. The service provides a simple pay-as-you-go pricing model, with prices starting at $0.0025 per hour connected and $10 for every 1M actions. Customers like CarFinance 24/7 are already using Sync to coordinate their call center agents and give them real-time visibility of customer data.
