Whalebird

Whalebird is a desktop client for Fediverse platforms such as Mastodon, Pleroma, Friendica, Firefish, Gotosocial, and Pixelfed. It presents a single‑column interface that resembles popular messaging tools, with a side menu that collapses on narrow screens. The application supports multiple accounts and updates timelines through streaming, delivering desktop notifications for new events.

Users can choose from a range of color themes, including a dark theme that matches the Mastodon web appearance. The client is built for macOS and is released as free software without advertisements, relying on donations for support.

The design focuses on a streamlined, Slack‑like UI while offering the ability to switch accounts and receive real‑time updates, making it suitable for individuals who want a lightweight, native desktop experience for interacting with various Fediverse services.
