Junie

June 11, 2026 · View on GitHub

An LLM-agnostic coding agent built for real-world development — by JetBrains.

Junie is an AI coding agent that lives in your terminal, integrates with your IDE and CI/CD pipelines, and helps you ship code faster. Give it a task in natural language — fix a bug, implement a feature, review a PR — and Junie handles the rest. Like your real coding buddy.

🚀 Get started

📦 Install

For more installation options and details, see the quickstart guide.

macOS / Linux:

curl -fsSL https://junie.jetbrains.com/install.sh | bash

Windows:

powershell -NoProfile -ExecutionPolicy Bypass -Command "iex (irm 'https://junie.jetbrains.com/install.ps1')"

Alternative options

macOS (Homebrew):

brew tap jetbrains-junie/junie
brew install junie

npm:

npm install -g @jetbrains/junie

🔀 Try another update channel

If Junie is already installed, you can run the latest build of a different channel for a single launch without changing your installed default. The shim fetches and installs that channel's latest build (if not already present), then launches it:

junie --eap            # run the latest EAP build, just this once
junie --nightly        # latest nightly
junie --experimental   # latest experimental
junie --release        # latest stable release
junie --channel=eap    # equivalent explicit form

Pin a specific build of a channel with --use-version:

junie --eap --use-version=122.1          # run EAP build 122.1
junie --channel=nightly --use-version=1998.1

A plain junie afterwards still launches (and auto-updates) your default channel — nothing about your existing install is changed.
