Vibe CodingEditor & IDE
JetBrains Junie
JetBrains' agentic coding assistant built into IntelliJ-based IDEs — plans and executes multi-file changes with full access to the IDE's own code understanding.
Junie is JetBrains’ agentic coding assistant for IntelliJ-based IDEs (IntelliJ IDEA, PyCharm, WebStorm, and others), able to plan and carry out multi-file changes using the same deep code-understanding engine — indexing, refactoring, inspections — that powers the rest of the IDE.
Why it stands out
- Built on JetBrains’ existing static analysis and indexing, rather than a bolt-on chat window with shallower codebase awareness.
- Works across the whole JetBrains IDE family, not a single language or framework.
- Runs alongside JetBrains’ existing refactoring tools, so agent-made changes benefit from the same correctness checks a human edit would.
Good for
Developers already working in a JetBrains IDE who want an agent that shares the IDE’s own understanding of the code rather than a separate tool.
