JetBrainsAI Coding Agent

Junie

AI coding agent from JetBrains that plans and makes multi-step code changes inside JetBrains IDEs, using their index, test runners, and debugger. It also runs from Junie CLI in the terminal, GitHub Actions, and GitLab CI/CD, on models from several AI labs or your own keys.

The 30-Second Take

Pick Junie if your engineers live in IntelliJ IDEA, PyCharm, Rider or another JetBrains IDE.

It works through the IDE's index, run configurations, test runners and debugger, and is bought through JetBrains licenses. Junie CLI runs the same agent in the terminal and in GitHub and GitLab pipelines.

Best fit
Teams on JetBrains IDEs that want an agent bought and governed with their existing JetBrains licenses.
Main constraint
Included AI Credits are small, 10 a month on individual AI Pro and 35 on AI Ultimate, so daily agent use runs on top-ups or your own model keys.
First move
Pilot on AI Ultimate seats with a per-user credit limit and a .junie/AGENTS.md in each pilot repository.

Why

Watch the credits: daily agent use spends the included AI Credits in days or weeks, and they bill at provider API rates. Budget for top-ups or your own model keys before daily use starts.

Comparisons

How does Junie compare with the alternatives?

  1. Junie vs Claude Code

    • AI Coding Agents

    Pick Junie for depth inside JetBrains IDEs and Claude Code for one agent across the terminal, editors, desktop, and web. Junie is bought with JetBrains AI licenses and runs models from several providers. Claude Code comes with Claude plans or Anthropic API usage, and runs in JetBrains through a plugin or as Claude Agent in AI Chat.

  2. Junie vs GitHub Copilot

    • AI Coding Agents

    Junie suits teams governed in JetBrains Central; Copilot suits teams that assign pull request work on GitHub. Copilot also runs in JetBrains IDEs and inside JetBrains AI Chat, and Junie CLI can run on a Copilot subscription. Junie is metered in JetBrains AI Credits at provider API rates, and Copilot in GitHub AI Credits pooled per organization.

How you buy it

US$20

Per user per month for an organization AI Pro license. AI Ultimate is US$60.

Source 1, JetBrains, JetBrains AI plans and usage: JetBrains AI plans and usage

Details

With a JetBrains AI license. Individuals: AI Pro US$10 or AI Ultimate US$30 per month. Organizations: AI Pro US$20, AI Ultimate US$60, or AI Enterprise US$60 per user per month. AI Free costs nothing, and the All Products Pack and dotUltimate include AI Pro.

Cost drivers

20 credits

Per organization AI Pro seat every 30 days, each credit worth US$1.

Source 1, JetBrains, JetBrains AI plans and usage: JetBrains AI plans and usageSource 4, JetBrains, JetBrains Central plans and pricing: JetBrains Central plans and pricing

Details

Each license adds AI Credits every 30 days: 10 or 35 for individual AI Pro or AI Ultimate, 20 or 70 per organization seat. One credit equals US$1 charged in your local currency. Top-up credits last a year, and requests on your own provider keys bypass credits and bill at the provider's rates.

Where it runs

JetBrains IDEs

Every major JetBrains IDE, plus a CLI, ACP editors, a GitHub Action, and GitLab CI.

Details

The Junie tool window in IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, RubyMine, RustRover, CLion, Rider, and Android Studio. Junie CLI runs on macOS, Linux, and Windows, and Junie also runs in JetBrains Air, the Junie GitHub Action, and GitLab CI/CD, self-managed included.

What to verify

No OS sandbox

Release builds run agent commands unsandboxed, so approvals and the allowlist carry the risk.

Details

Junie runs commands without approval once they sit on the Action Allowlist or Brave mode is on, so those settings carry the risk. Check whether your organization runs on JetBrains Central, where admins set per-user AI credit limits and purchased credits join one pool, and review the JetBrains AI data collection and use policy.

  1. Plan

    1. Work planning: Supports

      Work planning, supports. Plan mode saves requirements and technical design with delivery stages under .junie/plans before code changes. Junie accepts tasks from GitHub issues, Jira, and YouTrack. Those trackers retain the planning record.

  2. Build

    1. Codebase context: Core

      Codebase context, core. Junie uses the JetBrains semantic index to search symbols and edit code structures. It adds AGENTS.md guidelines to every task.

    2. Coding: Core

      Coding, core. This is Junie's primary role. It plans and makes multi-file code changes from the IDE's AI Chat, the Junie tool window, or Junie CLI.

    3. Agent runtime: Core

      Agent runtime, core. Developers direct Junie in JetBrains IDEs, Junie CLI, JetBrains Air, or ACP-compatible editors. They approve actions and review diffs there.

    4. Tool execution: Supports

      Tool execution, supports. Junie gates terminal commands and MCP tools with approvals and an Action Allowlist. Release builds have no OS-level sandbox for those commands.

  3. Validate

    1. Debugging: Supports

      Debugging, supports. Debug mode drives the IDE debugger to investigate failures before editing. Junie sets breakpoints and evaluates expressions in the live session.

    2. Testing: Supports

      Testing, supports. Tests are discovered and run through the IDE's test runners, and Junie can write new ones. Dedicated systems supply testing infrastructure.

    3. Code review: Supports

      Code review, supports. The /review command checks diffs against project guidelines, as do the GitHub Action and GitLab integration. The team retains final review authority.

    4. Application security: Touches

      Application security, touches. A Junie GitHub Action recipe scans commits for secrets. A separate platform owns application security.

  4. Ship

    1. Source control: Touches

      Source control, touches. Parallel tasks run in Git worktrees, and pipelines open pull or merge requests on GitHub and GitLab. The Git host stays the source-control system of record.

    2. CI/CD: Touches

      CI/CD, touches. Headless Junie CLI and the GitHub Action run tasks in pipelines, as does Junie GitLab CI/CD. The CI platform handles delivery.

  5. Operate

    1. Observability: Touches

      Observability, touches. Junie investigates production issues from supplied logs or reproductions. A separate tool supplies observability.
