Install ECA

ECA is written in Clojure and compiled into a native binary via GraalVM.

Auto install — ECA is already downloaded and updated automatically by all official editor plugins, so you don't need to handle it manually. The tabs below are only for users who want to install ECA themselves.

Where do you want to use ECA?

ECA in Emacs

The eca-emacs plugin bundles and keeps the ECA binary up-to-date automatically.

Install the plugin for Emacs and you're done. No separate server install is needed.

Install eca-emacs plugin Auto-downloads the ECA server on first launch

ECA in VS Code

The eca-vscode plugin bundles and keeps the ECA binary up-to-date automatically.

Install the plugin for VS Code and you're done. No separate server install is needed.

Install eca-vscode plugin Auto-downloads the ECA server on first launch

ECA in Neovim

The eca-nvim plugin bundles and keeps the ECA binary up-to-date automatically.

Install the plugin for Neovim and you're done. No separate server install is needed.

Install eca-nvim plugin Auto-downloads the ECA server on first launch

ECA in IntelliJ

The eca-intellij plugin bundles and keeps the ECA binary up-to-date automatically.

Install the plugin for IntelliJ and you're done. No separate server install is needed.

Install eca-intellij plugin Auto-downloads the ECA server on first launch

ECA Desktop

A standalone desktop app for ECA, built with Electron. Download the latest release for your platform directly from GitHub Releases — the ECA server is bundled, and supported formats auto-update in place.

AppImage Recommended .deb Flatpak
AppImage Recommended .deb

AppImage is the recommended format — it auto-updates in place via electron-updater. .deb does not auto-update; upgrade by downloading a fresh .deb when a new release ships. Flatpak (x86_64) runs the app sandboxed — install with flatpak install --user eca-linux-x86_64.flatpak, upgrade by installing a fresh bundle. In every format the managed eca server keeps auto-updating on its own.

.dmg Recommended .zip
.dmg Recommended .zip

Both .dmg and .zip auto-update in place via electron-updater. If macOS Gatekeeper blocks the app on first launch (unsigned builds), right-click the app in Applications and choose Open.

Windows builds are planned

Native Windows installers aren't shipping yet. In the meantime, you can run ECA through the VS Code or IntelliJ plugin on Windows, or build from source.

ECA CLI

eca-cli is a keyboard-driven terminal client for ECA, no editor required. It downloads and keeps the ECA server up-to-date automatically.

Install it with the script below and run it from your project directory. No separate server install is needed.

bash 
# Install or update eca-cli
bash <(curl -fsSL https://raw.githubusercontent.com/editor-code-assistant/eca-cli/main/install)

# Start it from your project directory
cd your-project
eca-cli

The script requires curl and tar, and installs a single self-contained eca-cli binary for Linux or macOS (x86_64 / arm64) in ~/.local/bin (/usr/local/bin as root); pass --dir <dir> to pick another place. On other platforms, run the eca-cli.jar release with Babashka: bb eca-cli.jar.

Install the ECA server manually

Not recommended

Most users don't need this — editor plugins auto-download the server. Use one of the options below if you want to manage the eca binary yourself, e.g. for scripted setups, CI, containers, or air-gapped machines.

Stable release:

bash 
bash <(curl -fsSL https://raw.githubusercontent.com/editor-code-assistant/eca/master/install)

Or if you face permission issues with the command above:

bash 
curl -fsSL https://raw.githubusercontent.com/editor-code-assistant/eca/master/install | sudo bash

Nightly build:

bash 
bash <(curl -fsSL https://raw.githubusercontent.com/editor-code-assistant/eca/master/install) --version nightly --dir ~/

The script requires curl and unzip.

We publish a custom Homebrew tap with the native compiled binaries:

shell 
brew install editor-code-assistant/brew/eca

Install using mise:

shell 
# Install the plugin
mise plugin install eca https://github.com/editor-code-assistant/eca-mise-plugin

# Install latest version of ECA
mise install eca
mise use -g eca

# Or install and use a specific version
mise install [email protected]
mise use -g [email protected]

# Verify installation
eca --version

You can download the native binaries from GitHub Releases directly, although this way it's easy to end up with an outdated ECA — the install script or a package manager are recommended instead.
