What is JetBrains Air?

JetBrains Air is JetBrains' agentic IDE released through Q1 2026, built around running multiple AI agents concurrently inside one development environment. It bundles Junie (JetBrains' own AI agent), plus integrations to run Codex, Claude, and Gemini in parallel agent panes. Air is the productized successor to JetBrains' earlier AI Assistant and Junie products, repositioned as a multi-agent IDE for developers who want model flexibility rather than locking into one vendor's stack.

How does JetBrains Air compare to Cursor 3?

Both are agentic IDEs with parallel agent execution. Cursor 3 (April 2026) added cloud agents on isolated VMs, /worktree for branch isolation, self-hosted agents, and parallel Agent Tabs — and is built on a VS Code fork. JetBrains Air is built on JetBrains' own IDE platforms (IntelliJ, PyCharm, etc.) and emphasizes orchestrating multiple model vendors in one IDE. If you live in JetBrains IDEs already, Air is the natural choice. If you live in VS Code or want the most polished IDE-first agent experience, Cursor 3. Cursor 3 is generally faster on benchmarks; Air is broader on model flexibility.

How does Claude Code fit in this comparison?

Claude Code is the terminal-first option. It runs in your terminal alongside whichever IDE you use and pairs particularly well with Anthropic's Claude Opus 4.7. JetBrains Air can run Junie CLI (the terminal counterpart of JetBrains' agent stack) which lets you switch between models including Claude Sonnet and Gemini 3 Flash — flexibility Claude Code does not offer. For developers who want a terminal-first agent and are already invested in Anthropic's stack, Claude Code wins. For developers who want a terminal agent with model flexibility, Junie CLI is the JetBrains alternative.

Which one should I pay for in May 2026?

JetBrains shop developers: Air. VS Code-native or fork-tolerant developers: Cursor 3. Anthropic-stack-committed developers who prefer terminal: Claude Code. Many serious developers in May 2026 use two — typically Cursor 3 or Air as the IDE, plus Claude Code in the terminal for autonomous work. JetBrains' April 2026 research found Claude Code shares second-place adoption at 18% of developers worldwide, signaling the IDE-plus-terminal pattern is now mainstream rather than niche.

JetBrains Air vs Cursor 3 vs Claude Code (May 2026)

The agentic-IDE category split in three clear directions through April 2026. Cursor 3 deepened its multi-pane agent story. JetBrains Air productized multi-agent orchestration. Claude Code stayed terminal-first and won meaningful real-developer adoption. Here’s how the three actually compare for May 2026.

Last verified: May 1, 2026

The three positions

Cursor 3 — Single editor (VS Code fork) with the most polished agent-first IDE experience. Cloud agents on isolated VMs, /worktree branch isolation, self-hosted agents, parallel Agent Tabs.
JetBrains Air — Multi-vendor agent orchestration inside JetBrains IDEs. Run Junie, Codex, Claude, and Gemini concurrently. Built on IntelliJ, PyCharm, WebStorm, GoLand, and the rest of JetBrains’ platform.
Claude Code — Terminal-first AI coding agent built around Anthropic models. Pairs with whichever IDE you use; works as the autonomous-work counterpart to your editor.

The three aren’t strictly mutually exclusive. The most productive May 2026 setups often combine an IDE (Cursor 3 or Air) with a terminal agent (Claude Code or Junie CLI).

Where each one wins

Cursor 3 — best polished IDE-first agentic experience

Cursor 3 (released April 2026) is the most polished single-editor agent experience. The April 2026 release added:

Cloud agents on isolated VMs. Hand off work to vendor-managed sandboxes; review diffs like PRs.
/worktree. First-class isolated branch changes inside the IDE; multiple parallel changes against different branches without manual stash-juggling.
Self-hosted agents. Run agents on your own infrastructure for security or compliance reasons.
Parallel Agent Tabs. Multiple agents running concurrently against different tasks in the same project.

Best for: VS Code-native developers, individual contributors, fast iteration cycles, teams without strict IDE policies.

Pricing: Pro $20/mo, Business plans available. Cloud agent minutes meter on heavier use.

JetBrains Air — best multi-vendor orchestration

JetBrains Air’s differentiator is running multiple agent vendors concurrently in one IDE. A typical Air setup might have:

Junie running on Sonnet 4.7 for everyday refactors.
Codex running on GPT-5.5 for long autonomous work.
Claude running on Opus 4.7 for careful coding.
Gemini running on 3.1 Pro for multimodal analysis (visual debugging, doc-image review).

This isn’t trivial to replicate in Cursor 3 (which routes through one model per tab). Air also benefits from JetBrains’ deep IDE features — refactoring tools, debuggers, profilers, language-server quality — that VS Code-fork IDEs don’t match.

Best for: JetBrains-shop teams (which is most enterprise Java, Kotlin, Python, Go shops), polyglot developers who switch IDEs by language, teams that want model flexibility without committing to one vendor.

Pricing: AI Assistant included in JetBrains AI Pro plans starting around $24/mo per user; agent credits metered.

Claude Code — best terminal-first autonomous agent

Claude Code is the terminal-first option. It runs in your terminal and works alongside whichever IDE you have open. Strengths:

Strongest model pairing in May 2026. Claude Opus 4.7 leads SWE-bench and Graphwalks; Claude Code is built around it.
Terminal-first means autonomous-work-friendly. You can leave Claude Code running in a tmux pane, ssh session, or background process, and review its work asynchronously.
Clean integration with Claude Code Cloud. April 2026 reset usage limits and added cloud-side execution for delegated work.

Trade-off: locked to Anthropic models. If you want to switch to Gemini 3.1 Pro for a multimodal task or run a quick experiment with GPT-5.5, you need a different tool. Junie CLI fills that gap inside the JetBrains ecosystem.

Pricing: Included in Claude Pro $20/mo, Claude Max $100/mo, or via API tokens for self-managed use.

What JetBrains’ own research shows

JetBrains’ April 2026 research blog reported on actual developer usage at work:

Cursor remains the most popular AI IDE among the surveyed developers.
Claude Code now shares second-place adoption at 18% of developers worldwide.
Awareness of Claude Code rose from 31% (April–June 2025) to 49% (September 2025) to 57% (January 2026).

The data point that matters: Claude Code is being adopted alongside IDE choices, not instead of them. The pattern is mainstream now: an IDE plus a terminal agent. JetBrains Air aims to consolidate this into one product; Cursor 3 + Claude Code is the de facto two-product alternative.

Decision tree

You live in JetBrains IDEs (IntelliJ, PyCharm, GoLand, WebStorm, etc.) → JetBrains Air. Don’t switch IDEs to chase agent features; Air is competitive and the IDE quality matters.
You live in VS Code or a VS Code fork → Cursor 3. The most polished agent-IDE experience as of May 2026.
You want a terminal-first autonomous agent → Claude Code (Anthropic-stack) or Junie CLI (multi-model). Pair with whichever IDE you already use.
You want everything → Cursor 3 + Claude Code, or Air with multiple model integrations. Both are reasonable two-product setups.
You’re starting fresh → Cursor 3 + Claude Code is the path of least resistance. Largest community, strongest models, fastest iteration cycle.

What changed in April 2026

The IDE landscape shifted meaningfully in the last month:

Cursor 3 cloud agents (April 2026) — first-class cloud handoff makes the IDE genuinely multi-mode (local interactive + cloud delegated).
JetBrains Air productization (Q1 2026) — multi-vendor agent orchestration is now packaged rather than DIY.
Claude Code Cloud (April 23, 2026) — usage limits reset, cloud-side execution shipped, terminal agent gets cloud parity.
Junie CLI — terminal counterpart to Junie released, with explicit model flexibility (Claude Sonnet, Gemini 3 Flash, etc.).

The category has matured from “AI assistance in editors” to “AI-native development environments.” May 2026 is the first month where the three big positions (Air, Cursor 3, Claude Code) all have their April releases bedded down enough to compare cleanly.

What’s missing from each

Cursor 3 — multi-vendor orchestration is per-tab rather than per-task; running four models on the same task in parallel is harder than in Air.
JetBrains Air — community share and third-party tooling are smaller than Cursor 3’s; some advanced JS/TS workflows are still smoother in Cursor.
Claude Code — locked to Anthropic models; if Anthropic has an outage or rate-limits you, your workflow stops. (Claude Code does support self-hosted Claude variants on enterprise plans.)

Bottom line

JetBrains Air for JetBrains shops with multi-vendor needs. Cursor 3 for VS Code-style developers wanting the most polished IDE-first agent experience. Claude Code for terminal-first autonomous work paired with any IDE. The May 2026 default for serious developers is two tools — an IDE and a terminal agent — and JetBrains’ research data says this is now mainstream practice. Pick the IDE that matches your stack, pair it with a terminal agent, and you’re set up for the rest of 2026.
