Mixky is a Chrome extension designed to integrate timelines from multiple social media platforms, specifically Bluesky, Mastodon, and mixi2, into a single interface. This tool allows users to view and post updates across these networks without the hassle of switching between different tabs or applications. It features a unified timeline that displays posts in chronological order and offers filtering options to view specific platforms as needed.

Among its key features, Mixky enables cross-posting, allowing users to share content on multiple platforms simultaneously with just a click. The extension supports image posting with customized layouts and includes a privacy mode to blur the timeline for discreet browsing in public spaces. Additionally, it offers automatic linking for URLs, dark mode options, and robust security measures that ensure user credentials are securely stored. This makes it an ideal choice for users looking to manage multiple social media accounts efficiently.
