## Overview and Purpose
Bluesky is a decentralized, text-based social media platform founded as a response to the limitations of traditional, centralized networks like Twitter/X[2][3]. Its core mission is to create a more open, customizable, and user-controlled online social experience by leveraging the AT Protocol, an open communication protocol for distributed social networks[2][3][7]. Unlike conventional platforms, Bluesky enables users and developers to shape the network’s features—such as algorithmic feeds, moderation tools, and community-building features—without relying on a single corporate authority[2][7].
## History and Development
Bluesky originated in 2019 as a research initiative within Twitter, led by then-CEO Jack Dorsey, who envisioned a decentralized future for social media[3]. After Twitter’s acquisition by Elon Musk in late 2022 and the ensuing platform turmoil, Bluesky accelerated its development, becoming an independent company in 2021[3]. It launched as an invite-only service in February 2023 and opened to the public in February 2024[2][3]. By May 2024, Dorsey had severed formal ties with the organization, which is now led by CEO Jay Graber[2][3].
## Growth and Key Achievements
Bluesky’s growth has been meteoric, especially following the 2024 U.S. presidential election, which triggered a significant migration of users from X/Twitter to more progressive, ad-free alternatives[1][4]. The platform’s user base skyrocketed from 13 million in late October 2024 to over 33 million by March 2025, with monthly visits exceeding 196 million[1]. At its peak, Bluesky boasted 2.5 million daily active users, though engagement has since declined to 1.5 million daily users as of September 2025[3].
A key innovation is Bluesky’s “marketplace of algorithms,” offering
