Free OpenSource Intellij plugin with support for AI pair programming via ECA
ECA (Editor Code Assistant) IntelliJ is an AI-powered pair-programming client for IntelliJ.
It connects to an external eca server process to provide interactive chat, code suggestions, context management and more.
For more details about ECA, features and configuration, check ECA server.
This extension will auto download eca and manage the process.
Just install the ECA plugin in Jetbrains marketplace.
Go to Preferences > Tools > ECA.
Check troubleshooting docs section.
To start the eca-webview:
bb dev-webviewThis will start Vite dev server on http://localhost:5173, so any changes will be updated on the IntelliJ live.
bb install-plugin <pathToYourIntellij> to install the plugin locally. The
installed plugin will point at the Vite dev server, so you also need
bb dev-webview running for it to render.
or
bb build-plugin to manually install via intellij the .zip.
If you want to install the plugin locally and run it without bb dev-webview
(i.e. with the production webview bundled into the zip, just like the
JetBrains-marketplace build), use:
bb install-prod-plugin <pathToYourIntellij> — builds the webview prod assets,
builds the plugin zip with is-dev stripped out, and unzips it into the
IntelliJ plugins directory.
or
bb build-prod-plugin — same build, but stops at producing the zip in
build/distributions/.
