Twitter (rebranded X after Elon Musk's 2022 acquisition) is a closed-source, centrally controlled social network where a single company sets the moderation policy, algorithm, and terms of access to the platform and its data.
Bluesky is the open-source, decentralized option, built on the AT Protocol so your identity and data aren't locked to one company's servers.
