JetBrains brings multi-agent Air layer to general availability

JetBrains moved its Air multi-agent layer from early access to general availability as part of the 2026.3 release wave, and ReSharper 2026.3 brings the same multi-agent choice to Visual Studio for the first time.

JetBrains announced on November 11, 2026, that its multi-agent Air layer has moved from early access to general availability as part of the 2026.3 release wave, letting developers run, direct and review coding agents from inside its IDEs, according to JetBrains' Air general availability announcement.

What changed in this release

Air reaches general availability on November 11, 2026, as part of the 2026.3 release wave across IntelliJ IDEA, Rider, PyCharm, WebStorm, CLion, PhpStorm, RubyMine and other IDEs.
Developers can run, direct and review agents including Claude Agent, Codex, Gemini, GitHub Copilot, Junie and other Agent Client Protocol (ACP) compatible agents from inside the IDE.
Parallel agent sessions use git worktrees to avoid collisions, alongside reusable session presets for repeatable tasks and line anchored Code Notes feedback.
Separately, ReSharper 2026.3, dated November 10, 2026, added Claude Agent and Codex as agent choices in Visual Studio's AI Assistant tool window alongside the existing Junie option, over the open Agent Client Protocol.
This is distinct from JetBrains' separate Air Governance layer for organization level spend and access control, which reached general availability on October 22, 2026.

What it means for people who build with AI

JetBrains is positioning the IDE itself, rather than any single vendor's agent, as the control plane for running and reviewing multiple competing coding agents side by side, and for the first time brings that choice into the .NET and Visual Studio ecosystem. JetBrains cites an internal statistic that 49% of developers now spend four or more hours a week reviewing AI generated output as the problem Air addresses.

Availability and licensing

A free tier is available through Junie Lite with just a JetBrains Account, while Claude Agent still requires a JetBrains AI subscription or an Anthropic API key.
In ReSharper, Claude Agent and Codex usage draws from a JetBrains AI subscription quota and does not support bring your own API keys, while Junie Lite remains free with just a JetBrains Account and no ReSharper license required.
ReSharper 2026.3's AI agent features are unavailable in mainland China.
