Updated: 2026-10-26
What is Junie?
Junie is JetBrains' AI programming agent. A positioning statement on the official homepage reads "The most cost efficient coding agent", and it emphasizes that it "works with any model you choose". Unlike coding assistants that rely solely on the company's own models, Junie places greater emphasis on model interchangeability and controllable execution: it is marked on the official website as being powered by the IntelliJ IDEA engine and supports more than 10 models (BYOK).
Who is it for?
- JetBrains ecosystem users who want to directly use the same set of code intelligence to drive agents within their IDEs.
- Teams looking to switch models or control costs, as the official website recommends using powerful models for planning and fast models for implementation.
- Maintainers of legacy projects undergoing batch migration; typical scenarios listed on the official website include Spring Boot upgrades and supplementing test coverage.
- Teams integrating AI tasks into CI, which trigger GitHub Actions and GitLab CI/CD via issues.
Key features
6Junie CLI and Junie Lite
The official website provides the terminal installation command `curl -fsSL https://junie.jetbrains.com/install.sh | bash`, and Junie Lite has been newly launched. The official states that it is a free AI layer and does not require card binding.
Four Runtime Modes
Terminal runs directly in the terminal; Air enables cross-project operation and IDE code intelligence; GitHub Action is triggered by issues and PRs; GitLab CI/CD is triggered by issues or MRs.
Advanced Plan Mode
First draft structured requirements, designs and delivery plans before writing code. Plans are stored in `.junie/plans`, editable and commit-able, with separate planning and implementation across different models.
Live Prompting
Labeled as an exclusive feature by the official, it enables real-time corrections and direction adjustments during task execution without having to start over.
Human in the Loop
It can review, approve and guide key actions, with a dynamic allowlist that requires user confirmation before execution.
Remote Control and Agentic Debugging
Officially stated to enable initiating migration tasks from a laptop and checking progress on a mobile phone, featuring asynchronous execution via CLI and web-based monitoring.
How to use Junie
- The installation command directly executes remote scripts.
- It is recommended to download and review them first before running.
- the official website provides two sets of commands for Mac/Linux and Windows, which can be selected according to the system.
- Plans in `.junie/plans` can be committed to the repository, allowing the team to review the AI's execution intent during code reviews.
- The official pricing page offers three tiers: Free to Start, AI Pro, and AI Ultimate.
- Quotas and prices are subject to the current page.
- it's more prudent to start with the free tier to get the process up and running.
- Before execution, use the dynamic allowlist to mark delete and publish operations as confirmation-required entries.
- the official website also provides Custom Guidelines, Custom Subagents, and MCP Integration.
- Before connecting to third-party tools, confirm the permission scope.
