Watch videos together — synced playback, floating chat, zero countdowns.
Download 0.47.0-alpha · All releases · Release notes
Windows x64 zip on that tag: MeowWatch-windows-x64.zip (.sig). After the first install, MeowWatch updates itself in-place from a signed Cloudflare R2 manifest.
Remote watch parties usually mean voice-call countdowns and drift. MeowWatch gives you one room code, synchronized playback, and chat on the video.
- Start or join a room — the code copies to your clipboard.
- Load the same video on both machines (drag-and-drop or paste a URL).
- Stay in sync — play, pause, and seek propagate through Syncplay.
- Talk while you watch — floating chat, reactions, and typing indicators.
| Feature | Description |
|---|---|
| Precision sync | Custom Dart Syncplay client with stateful heartbeat and convergence. |
| Floating chat | Glass-card overlay with corner snap, peek tab, and Tab-key toggle. |
| Three themes | Cozy, Cinema Noir, and Glass Aurora — persisted in SQLite. |
| Drag & drop playback | Drop a local video; libmpv handles playback. |
| Continue watching | SQLite history with resume position and one-click resume. |
| Smart auto-pause | Pauses when sync drops or a friend disconnects (2 s debounce). |
| Reactions & typing | Emoji bursts and typing indicators over a control channel. |
| Signed auto-update | Ed25519-verified in-app updates from Cloudflare R2. |
- Room code copied to clipboard on create.
- Idle cat mascot while waiting for a friend.
- Chat card remembers dock corner and size per room.
- Auto-assigned username when the field is blank.
- What's-new modal after updates.
- Flutter Windows desktop with commands-in / streams-out architecture.
- Custom Syncplay protocol client (TCP + startTLS).
- Headless-testable pure logic split from widgets.
- Drift/SQLite persistence for profiles, history, and settings.
- Signed release pipeline with fail-closed updater verification.
- Six shipped product phases, 40+ alpha releases.
| Subsystem | Responsibility |
|---|---|
| VideoCore | libmpv playback, keyboard shortcuts, drag-and-drop |

| ChatStore | Messages, reactions, typing over Syncplay chat + control channel |
