This is the full guide to hosting a watch party with Mzelo. Create a free room, send one invite link, and watch movies, YouTube, anime, or any video together in sync — with chat, voice, and video in the same room.
https://mzelo.com/app/rooms/<room_code>. Send it to friends; they can open it directly or paste the room code into the lobby's "Join by code" box.A Mzelo room is a persistent space — it doesn't expire, so you can reuse the same room for every movie night. When you create one, you can set:
moon. The room then lives at https://mzelo.com/app/rooms/moon.You can edit all of these later from the room profile button inside the room.
Every room has a shareable URL of the form https://mzelo.com/app/rooms/<room_code>. The last segment is the room code. There are three ways to invite:
Mzelo supports five watch modes so you can handle almost any content source:
A synchronized YouTube player that loads the real YouTube player on each device, so quality and subtitle controls work as expected. You can:
This is the easiest mode for watching YouTube together, music nights, or reaction sessions.
Share your screen with or without audio. Audio capture during screen share works in Chromium-based browsers (Chrome, Edge, Opera). Firefox and Safari don't capture audio during screen share. The streamer needs a solid upload connection, so pick whoever has the best internet.
The web player plays any direct video URL — MP4, M3U8 streams, live streams, and more. Paste a link and go.
On the Android app, a built-in browser does this automatically — just play the video in-app for a moment and it will detect the streamable links for you.
pure: to the URL (e.g. pure:https://x.com/x.m3u8). For live streams, prepend live: so the player handles them correctly (e.g. live:https://x.com/x.m3u8).Stream a video file directly from your device to everyone in the room, with optional subtitle files. Only the web app can start a local media stream, but both web and Android viewers can watch it. Great for private content, personal recordings, or downloaded files.
A shared cloud browser that everyone in the room can see and that authorized users can remotely control. Unlike screen share, the stream isn't tied to your computer, so your internet connection doesn't affect quality. Free sessions last up to 3 hours; premium sessions have no time limit and support state saving (keep logins, resume where you left off). It supports extensions and a built-in VPN for changing regions when sites buffer.

| If you want to watch… | Best mode |
|---|---|
| YouTube videos, music videos, reaction content | YouTube Player |
| A movie or show from a streaming site | Virtual Browser or Web Player |
| Anime on sites you already use | Web Player (with the M3U8 extension) or Virtual Browser |
| Something on your computer only you have access to | Screen Share or Local Media Share |
| A live stream URL | Web Player with live: prefix |
| Downloaded MP4 / MKV file | Local Media Share |
Mic and camera are off by default. Everyone controls their own. When someone speaks, a blue ring appears around their avatar; enabled cameras replace avatars with the live video feed in the user list.
If your movie night is invite-only, here's the recommended setup:
Every user in a room has a role. In order of authority: King > Queen > Bishop > Knight > Pawn. The room creator is the Owner — effectively a higher-ranked King.
| Role | What they can do |
|---|---|
| Owner | Full control, including public/private switch, clearing bans, demoting other Kings, unbanning individuals. |
| King | Moderation (kick, ban, hush), role changes, virtual browser on/off, all watch modes. Cannot touch the Owner's special powers. |
| Queen | Controls most media (VB, YouTube, screenshare, web player, local share, games). Can use peer-to-peer file sending. Cannot kick/ban/promote users. |
| Bishop | Knight powers plus adding videos to the YouTube queue. |
| Knight | Mic, camera, image and file sharing. No media control. |
| Pawn | Chat, GIFs, emojis, and flying emojis only. No mic or camera. |
To change someone's role (or hush, kick, ban, ignore their chat or mic/cam), click their profile picture in the user list. Kings and the Owner can ban users by both username and IP, so registered accounts can't just switch IPs to rejoin.
Mzelo has multiple theatre modes so the room can match what you're watching:
You can also resize the chat by dragging its boundary, toggle the chat entirely, and switch between circle and square user-list items to focus on camera feeds.
Mzelo rooms can be decorated. Enable Decor Mode in Room Settings to personalize the visual space. Decor is visible on desktop web; mobile and the Android app see the standard room layout. This makes recurring hangouts feel like your group's own place.
See the dedicated decoratable watch party rooms page for more.
Between episodes or when nothing's playing, Mzelo has built-in group games:
You can also screen share a game from another app, or use the virtual browser for turn-based browser games.
Screen share audio is only captured in Chromium-based browsers (Chrome, Edge, Opera). Switch to one of those, or use the virtual browser / web player instead.
Enable the virtual browser's built-in VPN to change region. If your site blocks the region it's launched in, switching often fixes playback.
Check the "Persist chat" setting in Room Settings. When disabled, users who join or reload can only see new messages from that point on. Re-enabling restores access to older messages.
Combine approaches: ban them, enable Deny Guests, and consider locking the room. For extreme cases, recreate the room with a new code and share it only with trusted people.
Share the URL from your address bar, e.g. https://mzelo.com/app/rooms/<room_code>. On Android, share the room code from the create-room screen.
Web at mzelo.com on any device or browser, plus a native Android app on Google Play.
Rooms are public by default. In Room Settings, set Public off. Combine with Lock and promote trusted friends to King for the strongest privacy.
Yes. Enable your mic and/or camera whenever you want.
Yes — enable Decor Mode in Room Settings. Desktop web shows decor; other platforms see the standard room.
No. Rooms never expire. You can reuse them forever, or create multiple rooms for different purposes.
