Junie Can Now Run on Your Mac – No Credits, No Cloud (blog.jetbrains.com)

Junie has announced the launch of Junie Local, allowing the coding agent to run entirely on Mac devices without relying on cloud services or token-based credits. This offering optimizes user experience by removing the need for manual setup and model selection, as it comes pre-configured with the Qwen3.6-27B model. Users with an M5 Mac and 64 GB of RAM can install it with a single command, ensuring that all operations occur on their local hardware, protecting privacy and eliminating any concerns around data leaving their machine. The significance of Junie Local lies in its cost-free operation, empowering developers to tackle complex tasks like multifile refactors and test coverage without the usual financial constraints. By prioritizing prefill optimization, Junie Local achieves impressive throughput improvements, particularly on Apple’s M5 chip, and delivers comparable performance to leading models like GPT-5. The initial focus on Mac hardware is just a starting point, as Junie targets broader accessibility and plans to develop support for additional platforms in the future. Overall, Junie Local represents a major step towards on-device AI experiences for coding tasks, enhancing both privacy and efficiency for developers.
