How to watch HBO Max together with friends

Short answer To watch HBO Max together in sync, install the Watch Peak Party extension in both browsers, open the episode in the Max player, press Start party and send the invite link. You each stream from your own Max account, so the picture stays at full quality — the party shares only the position in the episode.

HBO Max has been Max and then HBO Max again, and the domain went with it. That kind of churn is normally where a watch-party tool quietly breaks: it hard-codes one hostname, the service renames, and the link you send lands nowhere. It is worth knowing how the extension handles it, because it tells you something about how it handles the rest.

What you need

• Chrome 116 or newer, or another Chromium browser — Edge, Brave and Arc all run it. That floor is minimum_chrome_version in the manifest, not a guess.
• The extension in both browsers. Playback is kept in step by the extension running on each side, so the person you are watching with installs it too. It is the only thing either of you has to do more than once.
• Your own HBO Max access. A party shares the position in a video, never the video itself and never your session. You each sign in to your own account.
• The title in both regions. HBO Max's catalogue and even its brand differ by market; in some countries the same content sits behind a local partner entirely.

The walkthrough

1. Open the episode

   Start the title so you are on a /video/watch/<id> address. The id is a UUID, sometimes followed by a second one — the extension accepts both shapes and reduces them to one canonical room target.

   

2. Click the badge and press Start party

   Same panel, same button, as on every other service.

   

3. Send the invite link

   Copy and send. Their tab opens the same episode and joins the room.

   

✓ You are done when both players sit on the same frame and pausing on one side stops the other.

The max.com and hbomax.com question

Both hostnames are matched by the extension, and both URL shapes parse to the same canonical target, so it does not matter which one you or your friend happened to have bookmarked. Because max.com redirects to the HBO Max domain after the rename, the canonical link the party issues uses the destination — which means the invite link survives the redirect rather than bouncing through it.

The practical version: paste whatever URL you have. If the party can identify the episode from it, the room points at the episode.

Watching an hour-long drama together

HBO Max's catalogue skews to the kind of show where talking over the dialogue is actively rude, so the panel's defaults are the right ones here:

• Type, don't talk. Chat is free and unlimited, and it is silent.
• Collapse the panel. Click the badge to fold the panel away during a scene; click again to bring it back. The player is never resized either way, so nothing reflows.
• Push-to-talk for the gasps. Hold `, react, release. The microphone closes when you let go.
