JetBrains has introduced two new tools for AI-assisted software development: Air, an environment for delegating coding tasks to multiple AI agents and running them concurrently, and Junie CLI, an LLM-agnostic coding agent.
Both were announced on March 9. Air, in public preview, can be downloaded from air.dev, while Junie CLI, in beta, is accessible at junie.jetbrains.com.
Air, now free for MacOS with Linux and Windows versions coming soon, is an agentic development environment, or ADE, built on the idea of integrating the essential tools for managing coding agents into a single coherent experience, JetBrains said. Serving as a single workspace where Claude Agent, Gemini CLI, Codex, and Junie CLI can work side-by-side, Air helps developers navigate a codebase and easily switch back and forth between different coding agents. Developers can mention a specific line, commit, class, method, or other symbol when defining a task, providing the agent with precise context instead of a blob of pasted text. And when the task is done, Air displays the changes in the context of the entire codebase, along with essential tools like a terminal, Git, and a built-in preview, according to JetBrains. Air will soon add support for additional coding agents via the Agent Client Protocol (ACP) through the ACP Agent Registry, the company noted.
