About Delta Chat
Email-based messenger steadily adding calls, mini-apps, and multi-transport
Delta Chat's desktop app is on a fast, feature-dense release cadence. Recent releases built out real-time calls (ringing tones, device selection, a 'who can call me' setting, TURN relays), WebXDC mini-apps (clickable links, faster and safer loading), channels with descriptions and view counts, and multi-transport support letting one account span several mail servers. The latest (v2.49.1) is a macOS crash hotfix.
