Junie
JetBrains’ coding agent that plans first and debugs with the real IDE debugger.
JetBrains’ coding agent for its IDEs, out of beta since June 2026. It plans before coding, uses the IDE’s own debugger and inspections, and supports remote runs and project-aware code review. Usage is metered through JetBrains AI credits.
