LLM-agnostic coding agent built for real-world development by JetBrains, with integrations for terminals, IDEs, GitLab, GitHub and other development tools.
Junie is a Code Generation AI coding agent by JetBrains that operates LLM-agnostically across terminals, IDEs, GitHub, and GitLab, with pricing starting at $10/month via the JetBrains AI Pro subscription or free with bring-your-own-key access. It targets professional developers and engineering teams already invested in the JetBrains ecosystem who want a flexible, model-portable agent rather than a tool locked to a single provider.
Built on top of the IntelliJ Platform, Junie understands projects the same way JetBrains IDEs do, giving it deeper structural awareness than generic terminal-only agents. It supports top-performing models including Claude Sonnet and Opus 4.6, GPT-5, GPT-5.4, GPT-5.3-codex, Gemini 3.1 Pro, Gemini 3 Flash, and Grok 4.1, and integrates with five major BYOK providers: OpenAI, Anthropic, Gemini, xAI, and OpenRouter. Standout capabilities include Planning Mode (which decomposes complex tasks into runnable steps), Live Prompting (allowing prompt updates mid-execution without restart), Custom Subagents, Agent Skills for domain-specific rules, MCP integration with one-click server installation, and Human-in-the-Loop control for reviewing key actions.
Compared to the dozens of other Code Generation tools in our directory of 870+ AI tools, Junie's differentiator is platform breadth combined with model freedom â it runs in terminal, JetBrains IDEs, Zed, Air, GitHub Actions, and GitLab CI/CD, while most competitors lock users into either a single editor (Cursor, Windsurf) or a single model family (Claude Code, GitHub Copilot). For JetBrains shops or polyglot teams, this combination of LLM agnosticism and CI/CD-native execution is rare. Pricing scales from AI Pro at $10/user/month (10 AI credits) to AI Ultimate at $30/user/month (35 credits), with an AI Enterprise tier coming soon for organizations needing higher limits and custom integrations.

Junie supports frontier models from Anthropic (Claude Sonnet/Opus 4.6), OpenAI (GPT-5, 5.4, 5.3-codex), Google (Gemini 3.1 Pro, 3 Flash), and xAI (Grok 4.1). You can switch models per task or per project, optimizing for cost or capability. This avoids the vendor lock-in common in competing agents.
One agent runs in your terminal, JetBrains IDEs, Zed, Air, GitHub Actions, and GitLab CI/CD. Trigger Junie from GitHub issues and PRs or GitLab issues and MRs, or invoke it locally during development. The shared agent state means context follows you between local and CI environments.
Planning Mode decomposes complex tasks into a reviewable, editable plan before any code is written, while Live Prompting lets you update instructions mid-execution without restarting. Together, these give granular Human-in-the-Loop control. This reduces credit waste on misunderstood tasks compared to fire-and-forget agents.
Connect your own API keys from OpenAI, Anthropic, Gemini, xAI, or OpenRouter to use Junie without JetBrains-side credits. This puts cost control, rate limits, and data routing in the user's hands. It's especially valuable for teams with existing enterprise contracts or strict data residency requirements.
Define your own subagents for recurring task types, apply Agent Skills for domain-specific rules, and write Custom Guidelines that encode team conventions. Combined with one-click MCP server installation, Junie can be tailored to specific codebases without rebuilding integrations from scratch. This makes it adaptable to enterprise environments with strong style or compliance requirements.
