Compose posts, share pages, and keep up with your Bluesky notifications right from your toolbar. Supersky is the fastest way to post on Bluesky. It's a beautiful composer that lives in your browser toolbar, so you can share a thought, a page, or a photo in seconds — without opening a new tab or losing your place. Click the toolbar icon (or press Ctrl+Shift+S, or Command+Shift+S on Mac) and start typing. Supersky handles mentions, links, images, and languages just like the official app, and posts straight to your account. WHAT YOU CAN DO • Compose and post to Bluesky from any page, instantly. • Post to multiple accounts — write once and cross-post to all of them in a single click. • @-mention autocomplete that finds people as you type. • Share the page you're on, a link, or highlighted text with a right-click. • Attach up to four images, each with alt text for accessibility. • Automatic rich link previews (link cards), just like the official app. • A live character ring so you always know how much room is left. • Draft autosave — close the popup and your text is still there. STAY IN THE LOOP • See your unread notification count as a badge on the toolbar icon. • Get optional desktop banners for new likes, replies, mentions, reposts, and follows. MAKE IT YOURS • Light, dark, slate, and system themes. • Nine accent colors. • Set a default posting language. PRIVATE BY DESIGN Supersky has no servers, no analytics, and no tracking. You sign in with a Bluesky app password, and your session stays on your device. The extension only ever talks to Bluesky's own services — your Personal Data Server (for posting and notifications) and Bluesky's official link-preview and image services. Your credentials and drafts never leave your browser. You can revoke access anytime from Bluesky's app-password settings. GETTING STARTED 1. Install Supersky and click the toolbar icon. 2. Sign in with your Bluesky handle and an app password (create one at bsky.app under Settings → App Passwords — never use your main password). 3. Start posting. Supersky is independent, open-source software and is not affiliated with or endorsed by Bluesky Social PBC.
