Instantbird is a lightweight, open-source messaging client that excels in customizable and text-based communication, but lacks audio and video calling capabilities. In contrast, Trillian offers a more feature-rich experience with audio/video support and social media integration, making it suitable for users looking for a comprehensive communication tool.
