Relay - All the power of Matrix. None of the complexity.

A native macOS chat app built with SwiftUI that wraps the Matrix Rust SDK via UniFFI-generated Swift bindings. Relay aims to feel like a first-class Mac app — fast, simple, and user-friendly — while speaking the Matrix protocol under the hood.

Feature Overview

• Room list & navigation — browse joined rooms with unread counts, avatars, sorting, and filtering.
• Rich timeline — text, emote, notice, image, video, audio, and file messages with proper grouping, date headers, sender avatars, and big emoji for emoji-only messages.
• Rich text rendering — messages display formatted bodies with interactive, clickable mentions.
• Message editing — edit previously sent messages.
• Message redaction — delete messages.
• Reactions — toggle emoji reactions via context menu, emoji picker, or long-press.
• Replies — swipe on a message to reply, rendered as overlapping bubbles with click-to-jump.
• Pin messages — pin and unpin messages, view pinned messages, and jump to them in the timeline.
• URL previews — link previews displayed as standalone cards alongside messages.
• Unread markers — a "New" divider appears at the first unread message with jump-to support.
• Attachments — stage images and files before sending via drag-and-drop, paste, or the attach button.
• GIF search — search and send GIFs via GIPHY.
• Username autocomplete — mention users with inline suggestions while composing.
• Typing indicators — see who is currently typing in a room.
• Room directory & room creation — discover and join public rooms or create new ones.
• Room details — view and inspect room name, topic, and members.
• Deep links — handle matrix: URLs and matrix.to links to open rooms directly.
• Direct messages — start a DM with any user from their profile.
• Infinite scrollback — paginate backwards through history with a single click.
• Auto-scroll — the timeline stays pinned to the bottom for new messages, but won't interrupt you if you've scrolled up.
• Session verification — verify new sessions with a redesigned in-app flow.
• Keychain-backed sessions — login credentials are stored securely in the macOS Keychain.
