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.
