FAQ

Rave Alternative FAQ

The most common questions from people moving from Rave.io to Kosmi.

What is the best alternative to Rave.io? ▼

Kosmi is the best Rave.io alternative in 2026. It lets you watch Netflix, YouTube, Disney+, HBO Max, Hulu, Amazon Prime, Plex and almost any streaming service together in perfect sync — directly in your browser. Unlike Rave, no app download is required, voice chat is built in, and there are dozens of multiplayer games you can play between movies.

Is Rave.io shutting down? ▼

Rave's future has been uncertain for some time, which is why communities like saverave.com have appeared trying to preserve the experience. If you're worried about losing your watch-party app, Kosmi is a safe, actively developed alternative that works in any browser today and won't disappear from the App Store overnight.

Does Kosmi work without downloading an app? ▼

Yes — that's one of the biggest differences. Rave is app-only (iOS and Android). Kosmi runs entirely in your web browser on desktop, laptop, phone or tablet. Just open a link and you're in the room. Native iOS and Android apps are also available if you prefer them.

Can I watch Netflix together on Kosmi like I did on Rave? ▼

Yes. Kosmi supports synced playback of Netflix, YouTube, Disney+, HBO Max, Hulu, Amazon Prime Video, Twitch, Plex, Google Drive videos and almost any website with a video on it. Everyone in the room watches at the exact same moment, and you can react with voice chat, video chat or text in real time.

Is Kosmi free like Rave? ▼

Yes, Kosmi is free to use. Create unlimited rooms, invite anyone with a link, watch together, voice chat, screen share and play games at no cost. There is an optional Premium tier that unlocks extras such as 4K screen share and bigger rooms, but everything you need for a classic Rave-style watch party is free.

Can I play games with friends on Kosmi too? ▼

Yes. This is a major thing Kosmi adds on top of the Rave experience. Every room has dozens of built-in multiplayer games — Poker, Cards Against Humanity, drawing games, retro consoles (NES, SNES, PlayStation), and more. Watch a movie, then jump straight into a game without leaving the room.

How is Kosmi different from Rave.io? ▼

Rave is a mobile-first watch-together app focused on synced video and chat. Kosmi is a full browser-based hangout: synced watch parties from many more sources, voice and video chat, screen share, and built-in multiplayer games — all in one room you can share with a link. No app, no account required for guests, and it's actively maintained.

Why Kosmi Is the Best Rave.io Alternative

If you're searching for a Rave alternative, a Rave.io replacement, or you landed here from saverave.com, you're in the right place. Kosmi is the watch-together app for the post-Rave era — built for synced video with friends, but on the modern web instead of being stuck inside a single mobile app.

An Actively Developed Rave Replacement

One reason so many people are looking for an alternative to Rave.io is the uncertainty around the app itself: missing updates, login problems, App Store hiccups, and a community that has spun up grassroots efforts like saverave.com to keep the experience alive. Kosmi is a stable, actively maintained product backed by a team that ships updates regularly. You don't have to wonder whether your watch-party app will still be there next week.

Works in Any Browser — No App Required

Rave is a mobile-only app. That's fine until your friend wants to watch on their laptop, or you want a bigger screen at home, or you're on a school or work computer where you can't install anything. Kosmi solves that: open a link in Chrome, Safari, Firefox or Edge and you're in the room. If you do want a native experience, there are iOS and Android apps too — but you never need them to join.

More Streaming Sources Than Rave

As a Rave alternative for Netflix, YouTube and beyond, Kosmi supports a much wider catalog of services: Netflix, YouTube, Disney+, HBO Max, Hulu, Amazon Prime Video, Twitch, Plex, Google Drive videos, Vimeo, Dailymotion and effectively any site with a video on it. Everything stays in perfect sync for the whole room.

Built-in Voice, Video and Screen Share

Rave gives you chat and voice. Kosmi gives you chat, voice, and video — plus full screen sharing. No more juggling a Discord call on the side just to see each other's reactions. It's all in one room.

Games and Hangouts, Not Just Watch Parties

One thing Rave never offered is what makes Kosmi a full-featured Rave app alternative: built-in multiplayer games. Poker, Cards Against Humanity, drawing games, retro NES/SNES/PlayStation classics — all playable right in the room, with no installs. When the movie ends, the hangout doesn't have to.

The Easiest Way to Bring Your Rave Friends Over

Switching is painless. Create a Kosmi room, copy the link, and drop it in whatever chat you're already using — iMessage, WhatsApp, Discord, Snapchat, Telegram. Your friends tap the link and they're in. They don't even need an account to join. If you're tired of asking everyone to download yet another app, Kosmi is the Rave alternative built for that exact problem.

The Best Rave Alternative for 2026

Whether you're a long-time Rave user worried about the app's future, a couple in a long-distance relationship, a group of friends scattered across time zones, or just someone who wants to watch something with another human tonight — Kosmi is the modern, browser-based Rave.io alternative built to last. Try it free, no download required.
