Agora Real-time Messaging (RTM) SDK for JavaScript

The Agora Real-time Messaging (RTM) SDK for JavaScript, currently stable at version 2.2.4, provides robust real-time interaction capabilities for client applications. This SDK enables developers to integrate feature-rich, scalable, and proven real-time engagement solutions, moving beyond basic messaging to support complex scenarios like conference control, interactive games, metaverse applications, online education, e-commerce, and smart devices. Version 2.x represents a significant iteration, offering enhanced functions, improved performance, and a better user experience compared to its predecessors. While an explicit release cadence isn't stated, the continuous iteration to version 2.x and ongoing updates (such as v2.2.8 released Feb 2026) suggest active development and maintenance. Key differentiators include its proven reliability with over 3000 customers, wide applicability across diverse use cases, and strong focus on scalable real-time messaging, often complementing Agora's RTC (Real-time Communication) offerings for voice and video.
