Bluesky's mobile app active user base has shrunk by approximately 52% over the last 18 months [1].
This decline highlights the volatility of social media growth following surge events, but it also signals a shift in how the company defines success. Rather than focusing solely on its own app, Bluesky is positioning its underlying open protocol as a foundation for a wider ecosystem of decentralized services.
Data from Similarweb indicates that monthly active users (MAU) fell to 10.4 million in June 2026 [1]. This represents a 27.2% decrease compared to June 2025 [1]. The platform previously maintained a higher quarterly average of approximately 22.1 million MAU during the period of decline [1].
Daily engagement has followed a similar downward trend. Daily active users (DAU) in July 2026 were approximately three million [1]. This is a 25.6% drop from July 2025 [1].
Industry analysts said the dip follows a significant surge in interest after a previous election cycle [1], [2]. However, the company's strategic focus has expanded beyond the standalone application [2]. While the app's numbers are falling, the decentralized protocol that powers the network is being adopted by other third-party services [1], [2].
This transition suggests a move away from the traditional "walled garden" model of social media. By allowing other developers to build on its protocol, Bluesky is attempting to foster a network where users can move their data and identities between different apps, a core tenet of the decentralized web.

The divergence between app usage and protocol adoption suggests Bluesky is pivoting from being a single destination to becoming a piece of internet infrastructure. If the protocol succeeds where the app struggled to retain users, Bluesky could influence the social media landscape by enabling interoperability, reducing the power of single-platform monopolies.
