Meta Platforms Inc. will discontinue its standalone Messenger desktop application for Windows and macOS on December 15, 2025. Users will be directed to use browser-based access or the main Facebook platform instead. The Messenger app was introduced to compete with video communication tools but has seen a decline in usage as users prefer mobile devices and web browsers. The shutdown will affect businesses that use Messenger for customer service, impacting features like notifications and offline message queuing. Users have expressed frustration over potential loss of chat histories and concerns about increased dependency on Meta's web portal. Alternatives like Signal and Telegram may attract former users. Meta's decision reflects a broader industry trend toward prioritizing mobile experiences and could allow the company to focus resources on metaverse development and AI features.
