🍃 Teamtype

Section titled “🍃 Teamtype”

Multiplayer mode for your text editor!

[!NOTE] This project used to be called “Ethersync” until October 2025. See this PR for our motivation.

Teamtype enables real-time collaborative editing of local text files. You can use it for pair programming or note-taking, for example. It’s the missing real-time complement to Git!

What Teamtype is not

Section titled “What Teamtype is not”

We are not a company, and don’t sell anything. We don’t require you to create an account. We don’t have access to your data, and don’t use it to train AI algorithms. We don’t serve you ads, and don’t track you.

We’re just a bunch of people building something we want to see in the world.

🚦 Project status

Section titled “🚦 Project status”

The project is under active development right now. We use it every day, but there’s still some bugs to be aware of.

📥 Installation

Section titled “📥 Installation”

1. Install the teamtype command

Section titled “1. Install the teamtype command”

Teamtype works on Linux, macOS, Android, and on the Windows Subsystem for Linux.

Binary releases

The releases on GitHub come with precompiled static binaries. Download one and put it somewhere in your shell’s PATH:

  • x86_64-unknown-linux-musl for Linux
  • universal-apple-darwin for macOS
  • aarch64-unknown-linux-musl for Android (use a terminal emulator like Termux)
Arch Linux 
sudo pacman -S teamtype

Nix

To put teamtype in your PATH temporarily, run:

nix shell nixpkgs#teamtype

Make sure to also have it in your PATH when you run the editors, or install it to your environment in your preferred way.

Via Cargo
Terminal window
cargo install teamtype

2. Install an editor plugin

Section titled “2. Install an editor plugin”

📖 Basic usage

Section titled “📖 Basic usage”

In the directory you want to share:

$ teamtype share


    To connect to you, another person can run:


    teamtype join 5-hamburger-endorse


Peer connected: adfa90edd932732ddf242f24dc2dcd6156779e69966d432fcb3b9fe3ae9831ab

Another person, in a separate directory (also works on the same computer):

$ teamtype join 5-hamburger-endorse


Derived peer from join code. Storing in config (overwriting previous config).
Storing peer's address in .teamtype/config.
Connected to peer: 5e6b787fff79074735eb9b56939269100de1e37bc7f7a4d29c277cc24f7ee53d

The directories are now connected, and changes will be synced instantly. You can open text files (using editors with a Teamtype plugin), and start collaborating in real time! :sparkles:
