JetBrains Junie

JetBrains Junie is an agentic coding assistant for JetBrains IDEs, the terminal, and automated CI/CD work. It suits developers who want structured plans, approval checkpoints, and freedom to choose an AI provider. Its strongest case is a JetBrains-centered workflow that can extend from local editing to repositories and pipelines, provided you can manage credit limits and usage charges.

Overview

Junie combines chat assistance, coding-agent mode, codebase indexing, and terminal access. The IDE plugin works with IntelliJ IDEA Ultimate and Community, PyCharm Pro, WebStorm, GoLand, PhpStorm, RubyMine, RustRover, CLion, Rider, and Android Studio, with supported versions varying by product. The same agent can run in a terminal or headlessly from CI/CD scripts, so it can handle work beyond an open editor.

Remote Control adds asynchronous CLI execution monitored through a web app. Junie can also start from GitHub issues and pull requests through a GitHub Action, or from GitLab issues and merge requests through GitLab CI/CD. Those options make it practical for teams that want coding tasks connected to their existing review queues rather than copied into a separate tool.

Key features

Planning and approvals

Advanced Plan Mode separates requirements, design, and delivery before edits begin. Plans can be changed and committed under .junie/plans, leaving a reviewable record of the intended approach. Junie asks users to approve important actions, while the CLI requests approval for sensitive operations unless brave mode is enabled or an action has been allowed. This is a meaningful control for delegated work, although users choosing maximum automation will need to accept less friction by changing those settings.

Models and project context

Junie supports models from OpenAI, Anthropic, Google, and xAI. The CLI accepts provider API keys directly. Junie Lite / BYOK works with any AI model, including locally run models, and adds no markup to provider rates; the trade-off is that model usage remains a separate provider cost. Persistent project guidelines and Agent Skills packages keep instructions reusable, while shared slash commands across the CLI and IDE through ACP reduce workflow duplication.

Sandbox and security

CLI sandbox mode is available on macOS and Linux, not Windows. It wraps terminal commands, but does not cover Junie file edits, MCP servers, hooks, or git operations, so it is a narrower boundary than the name might suggest. JetBrains says its tools follow security standards including SOC 2 certification. Support is provided through Discord, GitHub, a contact form, and a support guide.

Pricing

Free to Start costs nothing and includes 5 AI credits; billed AI usage is separate. It is suitable for occasional exploration, but the small allowance is unlikely to cover sustained agent work. AI Pro costs $8.33 per user per month and provides 10 AI Credits per 30 days, with anytime top-ups. It is the sensible entry plan for an individual who needs recurring usage but can monitor consumption.

AI Ultimate costs $25 per user per month and raises the allowance to 35 AI Credits per 30 days, also with anytime top-ups. It fits heavier users who prefer a larger included quota, though top-ups can increase the effective spend. A 30-day trial gives prospective subscribers time to assess their workflow before renewal. Junie Lite / BYOK costs nothing, includes a free model, and supports provider-key or local-model use; provider AI usage is billed separately, making it the better choice for users who already manage model accounts.

Platforms

Junie is offered as an extension on Windows, macOS, Linux, and the web, with the IDE plugin available in the supported JetBrains products and Android Studio. The CLI runs on Linux, macOS, and Windows, while its sandbox restriction excludes Windows. That makes the full command-isolation workflow a better fit for Unix-based development machines.

Who it's for

Choose Junie if your work already centers on JetBrains IDEs and you want one agent spanning editor, terminal, remote execution, and CI/CD. It is particularly well suited to developers who need plans and approvals before an agent changes a codebase, or who want to switch among major model providers. It is less compelling for Windows users who depend on sandbox mode, or for anyone seeking a single predictable bill without separate provider usage charges.

Pros and cons

• Pros: broad JetBrains IDE coverage; terminal and headless CI/CD operation; structured, commit-ready planning; approval controls for sensitive actions; multiple model providers and BYOK/local-model support; GitHub and GitLab workflow integrations.
• Cons: Free to Start has only 5 AI credits; paid quotas are monthly and top-ups cost extra; BYOK shifts usage billing to providers; sandbox mode is unavailable on Windows and does not cover every Junie operation.

Alternatives

GitHub Copilot is the better pick for broad device coverage, including Android and iOS, and a familiar freemium route with a free plan and trial. Choose Claude Code when you specifically want Claude’s ecosystem and are comfortable with its paid subscription structure. Devin suits users seeking a hosted agent with API access and plans that scale from limited free usage to higher-priced tiers.

Kilo Code is an alternative for open-source extensions across VS Code, JetBrains, and the CLI. Gemini CLI is a focused choice for Linux, macOS, and Windows users who want Google Account access and a free entry point. Aider is appropriate when an open-source, free pair-programming tool is the priority and separate model-provider costs are acceptable. Tencent CodeBuddy and Tongyi Lingma are other freemium coding-assistant options with extension-based workflows.

Verdict

JetBrains Junie is a strong choice for JetBrains developers who want an agent that can plan, request approval, and continue into terminal and CI/CD workflows. Pick it for that integrated control and model flexibility; look elsewhere if Windows sandboxing, unrestricted included usage, or one all-in provider bill matters more.
