How to Start a Watch Party or Hangout on Kosmi

Kosmi is a browser-based watch party and virtual hangout platform. You can start a room, invite friends with a link, sync a video from Netflix, YouTube, or another streaming service, and layer in games, music, voice, and video chat. According to Kosmi's site, it is free to use with no download and no sign-up, and no credit card is needed. A mobile app is available, but Kosmi recommends a desktop or tablet for the full experience.

Before You Start

• A modern browser on desktop or tablet is recommended for the full experience.
• No account is required to jump in, per Kosmi's site.
• If you plan to watch a paid streaming service, you still need your own access to that service. Kosmi integrates with streaming services; it does not replace a subscription.
• Optional Premium exists for extras, but the core platform is described as free.

Step-by-Step: Create a Room and Invite Friends

1. Open Kosmi and launch a room

Go to kosmi.io and use the launch option on the site. You do not need to create an account first. This drops you into a room you can customize.

2. Make the room your own

Kosmi rooms are customizable. You can design a private room as a virtual living room, drive-in, games room, coffee shop, or pub. You can also create multiple rooms and invite a different crew to each one.

3. Invite friends with a link

Invite people by sharing the room link. Because no sign-up is required, your friends can join directly from the link without creating an account or downloading anything.

4. Pick your video source

Kosmi integrates with popular streaming services and supports Netflix, YouTube, or any streaming service, with playback synced across everyone in the room. Choose your source and start playback; the sync keeps everyone on the same timestamp.

5. Add games, music, and chat

Inside the room you can layer on games, music, and video chat. Kosmi lists built-in games including 8 Ball Pool, Shuffleboard, Mini Golf, Four Colors, Cornhole, Blast Arena, Kosmic Kart, Cards Against Humanity, SNES Party, NES Party, PSX Party, OpenArena, Poker, Wortle, and card tables. Voice, video, and messaging are fully integrated.

6. Use shared tools when you need them

Kosmi also includes shared browsing, screen sharing, link sharing, and file sharing, so you can do everything together without juggling multiple services.

If You Are Joining Instead of Hosting

• Open the room link you were sent.
• No sign-up or download is needed.
• You land in the room and can watch, play, and chat with everyone else.

If You Are Flying Solo

Check the public rooms in the lobby, or invite a community you already belong to. Kosmi's site lists community-oriented entry points such as a Discord alternative and a Brazil-focused Discord alternative.

Quick Reference

Common Snags to Expect

• Streaming access is on you. Kosmi syncs playback, but each viewer still needs their own way to access a paid service.
• Mobile vs. desktop. A mobile app exists, but Kosmi recommends desktop or tablet for the full experience, so plan the main screen accordingly.
• Multiple groups, multiple rooms. If you are hosting different friend groups or colleagues, make separate rooms rather than mixing everyone into one.

Kosmi's own framing sums it up: watch, play, chat, create, with voice, video, and messaging fully integrated. Start with a room, share the link, and add video, games, and chat as you go.
