Open Source Dart SMS Gateways

BlueBubbles is a free, open-source messaging application that brings Apple's iMessage experience to Android, Windows, Linux, macOS, and web browsers. It connects to a companion server running on a Mac with an active Apple account to relay messages between devices. Users can send and receive text messages, images, videos, and other attachments. The application supports group conversations, message reactions, read receipts, and delivery information. Optional private API integration enables additional capabilities, including typing indicators, message effects, and advanced group management. Users can personalize the interface with themes and different visual styles. Built with Flutter, BlueBubbles provides cross-platform messaging while retaining the Mac-based infrastructure required for iMessage connectivity.
