# Junie — JetBrains coding agent for the terminal, JetBrains IDEs and CI, running on hosted or your own model keys. > Source: The Agents Index — https://theagentsindex.com/junie (structured, researched, re-verified) > Facts last verified: 2026-09-18 Junie is JetBrains' AI coding agent, built on the IntelliJ IDEA engine and distributed as a terminal CLI alongside a JetBrains IDE plugin. It is sold through the JetBrains AI subscription, or run at provider cost with your own model keys. | Fact | Value | | --- | --- | | Website | https://www.jetbrains.com/junie/ | | Price | from $10/month billed monthly, $8.33/month billed annually | | Free tier | Yes | Two standing free routes, neither time-limited. The Junie pricing page's 'Free to Start' tier includes 5 AI credits and then runs on your own provider key at 'Provider-rate pricing, zero markup' with 'AI usage billed separately'. Separately, the AI Free subscription tier gives 3 AI Credits per 30 days, but is unavailable in Android Studio, IntelliJ IDEA without Ultimate and PyCharm without Pro. A 30-day AI Pro trial exists alongside these, and dropping off it returns you to AI Free. ## What it does **Writes code** · Yes — Authoring new code from a natural-language task is the core loop; the vendor states it creates files and writes code itself, then verifies the result rather than only proposing a snippet. > To execute the task, it can autonomously run terminal commands, create new files, write or edit code, run tests, and verify the changes. > — https://junie.jetbrains.com/docs/junie-ide-plugin.html · Junie IDE plugin page, description of how Junie executes a task **Debugs and fixes** · Yes — It goes past reading a stack trace: a dedicated debug mode drives a live debugger, sets breakpoints and evaluates expressions, though that mode needs a connected JetBrains IDE to work. > Debug mode turns Junie CLI into an AI debugging assistant. Instead of editing source code, Junie CLI launches or attaches to a running program, manages breakpoints, inspects runtime state > — https://junie.jetbrains.com/docs/junie-cli-debug-mode.html · Debug mode page, opening description **Writes tests** · Yes — Test generation is documented as a first-class task rather than a side effect of writing code, driven through the portable agent-skills mechanism so output follows the project's existing test style. > Identifies untested paths and generates tests matching your project's existing test style. > — https://junie.jetbrains.com/docs/agent-skills.html · What you can do with skills table, Test coverage row **Reviews code** · Yes — A separate read-only review agent reviews diffs someone else wrote, comparing a branch against main or a named revision, and it also runs unattended on GitHub pull requests. > Use local code review when you want to get a quick sanity check before opening a pull request, review your own changes after a long coding session, or review your current branch against main. > — https://junie.jetbrains.com/docs/junie-review-agent.html · Code review agent page, How it works section **Whole-codebase work** · Yes — The vendor claims repository-wide edits rather than single-file assistance, and markets long-running migrations specifically as the case its asynchronous remote mode exists for. > It can introduce large-scale edits to your project, run tests or terminal commands, and use external tools when needed, while reporting progress to you. > — https://www.jetbrains.com/help/ai-assistant/junie-agent.html · Junie by JetBrains help page, opening paragraph **Ships it** · Partly — It reaches further than a diff, committing, pushing branches and opening pull requests through the GitHub Action, but no deployment or release step is documented anywhere on the site. > Turning issues into fixes: Junie creates pull requests with code changes or fixes from issue descriptions, PR reviews, or comments. > — https://junie.jetbrains.com/docs/junie-on-github.html · Junie GitHub Action page, Key features list ## How much it does unattended **Runs autonomously** · Yes — It completes multi-step tasks unattended, and a brave mode removes the approval prompts entirely; headless CI runs and GitHub Action triggers have no human in the loop at all. > You can allow Junie to execute commands or modify files without asking for confirmation. To enable this behavior, click in the chat input field and turn on the Brave Mode. > — https://www.jetbrains.com/help/ai-assistant/junie-agent.html · Junie by JetBrains help page, Enable Brave mode section **Multi-agent** · Yes — Custom subagents run as independent contexts that the main agent selects and delegates to, with their own model, tool restrictions and parallel execution across subtasks. > The main agent discovers all available subagents, selects the relevant subagent by matching its name and description to the task at hand, runs it as a subtask, and brings the result back > — https://junie.jetbrains.com/docs/junie-cli-subagents.html · Custom subagents page, How Junie CLI uses subagents section **Agent permissions** · Yes — It asks before sensitive actions by default and the boundary is editable: a JSON allowlist governs command execution, file edits outside the project, MCP tool calls and reads of secret files. > If brave mode is not explicitly enabled, Junie CLI will ask for user approval before running terminal commands, MCP tools, and other types of actions that are considered to be sensitive > — https://junie.jetbrains.com/docs/action-allowlist-junie-cli.html · Add commands to Action Allowlist page, opening paragraph ## Which models it runs on **Claude** · Yes — Anthropic models are reachable both through the JetBrains subscription and by pasting your own Anthropic key, and the CLI ships a built-in alias mapping onto Claude models. > BYOK (Bring Your Own Key) — models accessed using your own API key from a third-party provider such as OpenAI, Anthropic, Google, xAI, OpenRouter, or GitHub Copilot. > — https://junie.jetbrains.com/docs/junie-cli-model-selection.html · Model selection page, LLM providers list **GPT** · Yes — OpenAI models are reachable both through the JetBrains subscription's curated cloud set and by connecting your own OpenAI key directly, with built-in CLI aliases routing to them. > you can connect directly to providers like OpenAI, Anthropic, Google, xAI, OpenRouter, or GitHub Copilot. > — https://junie.jetbrains.com/docs/byok.html · Bring Your Own Key page, opening paragraph **Open models** · Yes — Open-weight models run two ways: through Ollama or LM Studio on any plan, or via the vendor's own Apple Silicon inference engine that ships a quantised Qwen model to your machine. > via OpenAI-compatible APIs, including Ollama and LM Studio > — https://www.jetbrains.com/ai-ides/buy/ · AI models comparison table, sublabel of the 'Local AI models' row, which is ticked in all four plan columns **Model choice** · Yes — You choose, not the vendor: four provider classes are supported and a flag forces a specific one, though leaving the default lets JetBrains pick on price-quality grounds. > Junie supports four types of LLM providers: > — https://junie.jetbrains.com/docs/junie-cli-model-selection.html · Model selection page, LLM providers section heading sentence ## Where you use it **In your editor** · Yes — It runs inside JetBrains IDEs and Android Studio, either from the shared AI Chat tool window or as a standalone plugin with its own tool window. > The recommended way to use Junie is from the single AI Chat in your JetBrains IDE: select Junie by JetBrains from the list of supported coding agents and have it downloaded automatically. > — https://junie.jetbrains.com/docs/junie-ide-plugin.html · Junie IDE plugin page, opening paragraph **On the command line** · Yes — The terminal is the primary surface, installed by a shell command on Linux, macOS and Windows, with interactive sessions, slash commands and shell passthrough. > Junie CLI is the agentic coding tool by JetBrains that provides an interactive terminal interface for developers to review, write, and modify code. > — https://junie.jetbrains.com/docs/junie-cli.html · Quickstart page, opening paragraph **In your pipeline** · Yes — A headless flag plus a published GitHub Action and GitLab CI integration let it act on issues, pull requests and failed builds without an interactive terminal. > You can run Junie CLI in headless mode without interactive UI in CI/CD environments and build pipelines. > — https://junie.jetbrains.com/docs/junie-headless.html · Headless mode page, Usage section introduction **In a browser** · Partly — The web app is a companion view onto a CLI session still running on your own machine, not a standalone hosted agent, and the vendor lists a dozen features it cannot do. > Remote mode lets you open your running Junie CLI session in a web browser and keep working on the same task from another device. > — https://junie.jetbrains.com/docs/junie-cli-remote-mode.html · Remote mode page, opening paragraph ## Whose machine it runs on **Self-hosted** · Partly — The agent binary always runs on your machine and models can be local, but running the surrounding JetBrains AI service on your own infrastructure is ticked for AI Enterprise alone. > On-premises, cloud, and hybrid deployment > — https://www.jetbrains.com/ai-ides/buy/ · Security and administration comparison table, deployment row: crossed for AI Free, AI Pro and AI Ultimate, ticked only for AI Enterprise **Open source** · No — The public repository carries installers, model profiles and a plugin rather than agent source, and its licence section reserves all rights and points at proprietary service terms. > © JetBrains s.r.o. All rights reserved. > — https://github.com/JetBrains/junie · README, License section ## What it costs to run **How it meters** · Yes — Two meters stack: a per-user seat, then AI Credits consumed by agent work, each credit pegged to a dollar. The bring-your-own-key path drops the credits and bills you at provider rates. > 1 AI Credit is worth USD 1.00 (charged in your local currency). > — https://www.jetbrains.com/ai-ides/buy/ · Top Up AI Credits section, note beneath the button **Free tier** · Yes — You can install and run it without payment details or a sales call, either on the standing AI Free plan or indefinitely against your own provider key. > Free to start. No card or subscription required. > — https://junie.jetbrains.com/ · Hero section, beneath the install command **API access** · Yes — You drive it from your own stack through the headless CLI with an API-key token, plus an ACP mode and a GitHub Action; there is no REST API for the agent itself. > Junie CLI requires an authentication token to run. To generate the token, go to junie.jetbrains.com/cli. > — https://junie.jetbrains.com/docs/junie-headless.html · Headless mode page, Authentication token section **MCP server** · Partly — MCP runs one way only: Junie consumes external MCP servers as a client. Another program reaches it through ACP instead, and no MCP server exposing Junie is documented. > You want Junie to serve requests initiated from an ACP client (instead of direct human interaction in the terminal). > — https://junie.jetbrains.com/docs/junie-cli-acp.html · Junie for ACP clients page, When to use ACP mode list **Bring your own key** · Yes — Six providers accept your own key, billing bypasses JetBrains entirely, and a supplied key wins over the subscription when the same model is reachable both ways. > With BYOK, Junie sends requests to LLMs using your API key directly. All usage is billed by the provider — no JetBrains AI subscription is required. > — https://junie.jetbrains.com/docs/byok.html · Bring Your Own Key page, How it works section ## Buying it for a team **A company can buy it** · Yes — Organisations buy it directly: every paid plan card offers an organisation purchase path, and the enterprise tier is sold per user through sales with team budget control. > Enjoy complete control of your team’s budget, security, and legal requirements. > — https://www.jetbrains.com/ide-services/ai-enterprise/ · You control your organization's AI usage section **Seat model** · Yes — Priced per named user on every tier, with each seat carrying its own credit allowance; no minimum seat count or upper ceiling is published on any plan page. > per user, per month, billed annually > — https://www.jetbrains.com/ide-services/ai-enterprise/ · Pricing section, Enterprise plan card **Pooled budget** · Partly — It splits: the included allowance is per seat and resets per seat, while separately purchased top-up credits are pooled across the organisation's licences. > for organizations they are shared across the team’s JetBrains AI licenses. > — https://lp.jetbrains.com/ai-ides-faq/ · Pricing and plans, What are top-up AI Credits? answer **Admin controls** · Partly — A developer can constrain the agent locally through the allowlist file on any tier, but organisation-wide policy such as company MCP rules is an enterprise capability. > Company-wide MCP policies > — https://www.jetbrains.com/ide-services/ai-enterprise/ · You control your organization's AI usage section, capability list **Audit log** · Partly — Administrative logging exists but is gated: the comparison table crosses it out for the free and both individual paid tiers and ticks it only in the enterprise column. > AI audit logs > — https://www.jetbrains.com/ai-ides/buy/ · Security and administration comparison table, AI audit logs row (ticked only in the AI Enterprise column) **Single sign-on** · Partly — SAML-style single sign-on with SCIM provisioning is real but sits behind the enterprise tier; the free and individual paid plans are crossed out on that row. > Advanced user and group access management > — https://www.jetbrains.com/ai-ides/buy/ · Security and administration comparison table, access management row labelled SSO, SCIM (ticked only in the AI Enterprise column) ## What happens to your code **Opt out of training** · Yes — Training on your code is off unless you switch it on, the exclusion is ticked on every tier including free, and the commitment is contractually extended to model subcontractors. > We will ensure that all AI Subcontractors commit not to use Your Inputs, Data, Outputs, and Suggestions for the training of their AI models > — https://www.jetbrains.com/legal/docs/terms/jetbrains-ai-service/ · JetBrains AI Service Terms of Service, clause on AI Subcontractors **Data residency** · Partly — No hosting region or jurisdiction is named for the standard cloud service; the only published control is the enterprise deployment choice, which lets an organisation keep it in-house. > On-premises, cloud, or hybrid deployment > — https://www.jetbrains.com/ide-services/ai-enterprise/ · Pricing section, Enterprise card, What's included? list **Getting out** · Partly — Unused allowance is lost rather than carried, and purchased credits expire after a year; the site documents no bulk export of sessions, plans or agent configuration. > AI Credits are valid for 12 months from their purchase date. > — https://www.jetbrains.com/ai-ides/buy/ · Top Up AI Credits section, note beneath the button **Certifications** · Yes — The Trust Center lists a SOC 2 Type II report scoped to Junie specifically, alongside GDPR; no ISO 27001 certification appears among the published compliance resources. > JetBrains tools adhere to industry-leading security standards, including SOC 2 certification, ensuring your organization's data is protected and our products are compliant with global regulations. > — https://junie.jetbrains.com/ · Proven compliance and security section ## Platform record (as of 2026-08-30) Reported by the code-hosting platform, not by the vendor. | Fact | Value | | --- | --- | | Stars | 31 | | Forks | 7 | | Last push | 2026-08-24 | ## Provenance Every fact above comes from the vendor.
