Take your time. See you on the island.

On the island

No big plans. Just being together.

  1. Be here, together

    Step into a voice room and catch up with familiar people. Do your own thing, with a friend within earshot.

  2. Leave a little of your voice

    Missed each other? Leave a voice bubble on the island. It will be there when your friends return.

  3. Make the island your own

    Owners and admins can arrange buildings and decorations, slowly giving your shared place a character of its own.

It starts with a share link

Sign in, then return straight to your friend's island

Open the link your friend sent. If you need to sign up or sign in, EchoBay returns you to the island preview afterwards. Confirm the visit to enter without replacing your home island.

  1. 01Open your friend's link
  2. 02Return to the preview after sign-in
  3. 03Confirm and enter the island

FAQ

Install and use

How do I install EchoBay on Windows?

Run the downloaded EchoBay-Setup-x64.exe and follow the prompts. It includes the required runtime files and creates a standard uninstall entry.

Why might Windows show an unknown publisher warning?

The Closed Beta installer does not yet have a commercial code-signing certificate. Download only from downloads.echobay.club and verify its SHA-256 if needed.

How do I install the Android APK?

After downloading, Android may ask you to allow installs from your browser. EchoBay never asks you to disable device security and is not distributed through third-party download sites.

Can I use EchoBay without installing it?

Yes. Open the web app in a supported desktop or mobile browser. Your browser will request microphone access the first time you join voice.

How do I join a friend's island?

Open their share link or enter the short code, preview the island, and confirm the visit. This does not replace your home island.
