Agentic-Ide

JetBrains launched Air into public preview today — and it’s not just another AI-enhanced code editor. It’s a fundamental rethink of what a development environment is when AI agents do the actual coding. The tagline from JetBrains captures the shift cleanly: traditional IDEs add tools to the code editor. Air builds tools around the agent. What Air Actually Is Air is JetBrains’ answer to the question: “What does an IDE look like if the primary user is an AI agent, not a human?” The answer involves several distinct design choices that set it apart from tools like Cursor, GitHub Copilot, or even the JetBrains AI plugin for IntelliJ IDEA. ...

The agentic IDE war is moving fast. JetBrains launched Air in public preview just yesterday, positioning itself as the agent-first development environment. Today, Zed — the performance-obsessed open-source editor — ships v0.227.1 with a feature that directly answers the multi-agent challenge: native parallel subagents. What’s New in v0.227.1 The headline feature is a new spawn_agent tool built into Zed’s AI assistant. When the AI determines a task would benefit from parallel execution, it can now spawn and run subagents in parallel — each handling a discrete portion of the work in its own context window — and then coordinate the results. ...

JetBrains Air entered public preview today — an agentic IDE built on the Fleet codebase that supports running multiple AI coding agents in parallel. If you’ve been following the agentic IDE space and want to get hands-on, this guide walks through installation, initial configuration, and your first parallel agent workflow. Prerequisites Before you start, confirm you have: A JetBrains account — Air requires a JetBrains account, even in public preview. Free accounts work during the preview period.
