JetBrains Junie

Junie is JetBrains’ coding agent. It runs as a CLI on macOS, Linux and Windows, inside JetBrains IDEs, and in GitHub and GitLab pipelines where it can work on issues and pull requests.

It’s paid for with JetBrains AI credits, worth $1 each, that reset every 30 days. In October 2026 JetBrains added Junie Lite, a free model tier for every JetBrains account, and an ECO mode for cheaper runs.

Who it’s for

Developers who already work in IntelliJ IDEA, PyCharm, WebStorm or other JetBrains IDEs, and anyone who wants a cheap agent with their own keys. JetBrains pitches it as “the most cost efficient coding agent”.

What stands out

• Plans you can commit. Advanced Plan Mode writes editable plans to .junie/plans before changing code.
• Steer mid-task. Live Prompting lets you redirect the agent while it works, with a dynamic allowlist for approvals.
• Remote Control. Start tasks from the CLI and monitor them in the web app.
• Same setup everywhere. Guidelines, skills and commands are shared between the CLI and IDE.
• CI built in. Runs as a GitHub Action and in GitLab CI/CD.
• No-markup keys. Bring keys from five providers, a Copilot sign-in or a local model, with no JetBrains fee.

Drawbacks and things to watch

• The free model has an end date. Junie Lite is offered until December 31, 2026, and its model may change.
• Small credit allowances. AI Pro’s 10 credits are worth $10 of usage, so heavy users will need top-ups or their own keys.
• Sandbox not on Windows. The optional sandbox mode, in Early Access, works on macOS and Linux only.
• Not available in China. The JetBrains AI service has been unavailable there since July 13, 2026; your own keys and local models still work.

Privacy and security

JetBrains says detailed code-related data collection is off by default, though its legal FAQ says it’s on by default for non-commercial licences, so check your settings. For organisations it stays off unless an admin enables it, and JetBrains AI Enterprise offers zero data retention. JetBrains says it holds SOC 2 certification.

Getting started

On macOS or Linux, run curl -fsSL https://junie.jetbrains.com/install.sh | bash; Windows has a PowerShell installer. Then run junie in your project folder. In a JetBrains IDE, Junie is available from the AI tool window.
