Block-based coding, together in real time

Built off of PenguinMod and TurboWarp

The first true collaboration tool built off TurboWarp and PenguinMod.

Projects stay on your own computer. A room closes when everyone leaves, so save your work with File, then Save to your computer.

Join a room

Got a room code from a friend? Type it here. Invite links open the room straight away.

Rooms can have a password; you'll be asked for it when you join.

What's new?

Universal settingsEvery setting in one menu, plus presets to make it work like Scratch or PenguinMod.
Room chatTalk to everyone in your room without leaving the editor.
Custom themesColours, gradients, fonts, animations and sounds, saved as a file you can share.
Paste ImagePaste a picture as a full-quality costume.
Steadier roomsLosing your connection no longer leaves a copy of you behind.

Collaboration

Start a room

Open the editor and choose Collaborate, then Create a room. Add a password if you like.

Share the code

Send friends the 8-letter room code or the invite link. They get a copy of your project.

Build together

Everyone edits at once: blocks, costumes, sounds and sprites stay in sync.

Save it

Anyone can save the project to their computer at any time.

Live cursorsSee where everyone is working, labelled with their name.

Script lockingA script someone is editing is outlined and read-only for others, so nobody overwrites each other.

Everything syncsBlocks, variables, costumes, sounds, sprites and their positions.

Room chatOptional text chat for the room, off until you turn it on.

PasswordsKeep a room private with a password. It never appears in invite links.

Reconnects by itselfA dropped connection rejoins in seconds and keeps the host.
