Cursor 3 vs Windsurf vs JetBrains Air (May 2026)
Cursor 3 vs Windsurf vs JetBrains Air (May 2026)
The AI IDE category split into three clear positions through April 2026. Cursor 3 added cloud agents and parallel agent tabs, taking the polish lead. Windsurf held steady at $15/month with Cascade as the value pick. JetBrains Air productized multi-vendor agent orchestration inside JetBrains IDEs. Here’s how to pick for May 2026.

Cursor 3 — most polished VS Code-fork AI IDE
Cursor 3 (April 2026 release) is the most polished single-editor AI IDE in May 2026. The April release added four meaningful capabilities:
- Cloud agents on isolated VMs — delegate work to vendor-managed sandboxes; review diffs like PRs.
- /worktree — first-class isolated branch changes; multiple parallel changes against different branches without manual stash-juggling.
- Self-hosted agents — run agents on your own infrastructure for security or compliance.
- Parallel Agent Tabs — multiple agents running concurrently against different tasks in the same project.
Wins: polish, agent feature depth, community size, model flexibility per tab, cloud delegation.
Loses: $20/mo is more expensive than Windsurf at $15/mo for similar core features, locked to VS Code-style editing (some IDE features lag JetBrains), cloud agent minutes can surprise on heavy use.
Best for: VS Code-native developers, individual contributors, fast iteration cycles, teams without strict IDE policies.
Windsurf — best value AI IDE
Windsurf at $15/month is the best price-to-feature ratio in the AI IDE category. Cascade (Windsurf’s agentic workflow system) handles multi-step tasks well, and the VS Code-fork base means most VS Code extensions work.
Wins: price ($5/mo cheaper than Cursor), Cascade agent quality, clean UI, lower learning curve than Cursor 3.
Loses: smaller community than Cursor, fewer cutting-edge features (no /worktree equivalent yet, no first-class self-hosted agents), the “value pick” framing means it lags on bleeding-edge features.
Best for: developers who want a great AI IDE without paying Cursor pricing, teams scaling to many seats where the $5/mo difference compounds.
May 2026 note: Windsurf added Claude Opus 4.7 backend support and improved Cascade’s long-running agent loops through Q1 2026. It hasn’t matched Cursor 3’s cloud agents on isolated VMs.
JetBrains Air — best for JetBrains-shop developers
JetBrains Air is the natural choice if you live in IntelliJ, PyCharm, WebStorm, GoLand, RubyMine, or any other JetBrains IDE. Its differentiator is running multiple agent vendors concurrently in one IDE:
- Junie running on Sonnet 4.7 for everyday refactors.
- Codex running on GPT-5.5 for autonomous work.
- Claude running on Opus 4.7 for careful coding.
- Gemini running on 3.1 Pro for multimodal analysis.
This isn’t trivial to replicate in Cursor 3 (which routes through one model per tab) or Windsurf (which uses Cascade).
Wins: multi-vendor orchestration, JetBrains’ deep IDE features (refactoring, debuggers, profilers, language-server quality), best-in-class for JVM languages and large enterprise codebases.
Loses: doesn’t work outside JetBrains IDEs, smaller community than Cursor, some VS Code extensions have no JetBrains equivalent, price is higher than Windsurf.
Best for: JetBrains-shop teams (most enterprise Java, Kotlin, Python, Go shops), polyglot developers who switch IDEs by language, teams that want model flexibility without committing to one vendor.
Decision tree
| You are | Pick |
|---|---|
| VS Code-native, want best AI IDE polish | Cursor 3 |
| VS Code-native, value-conscious | Windsurf |
| JetBrains-shop developer | JetBrains Air |
| Enterprise Java / Kotlin developer | JetBrains Air |
| Need cloud agent isolation | Cursor 3 |
| Need multi-vendor agent orchestration | JetBrains Air |
| Scaling many seats, price matters | Windsurf |
| Bleeding-edge feature appetite | Cursor 3 |
For most serious developers in May 2026, the IDE choice follows your stack. Don’t switch IDEs to chase agent features — Air is competitive for JetBrains stacks; Cursor 3 and Windsurf are competitive for VS Code stacks. The IDE-quality cost of switching outweighs marginal agent feature differences.
What changed in April 2026
Three meaningful shifts:
- Cursor 3 cloud agents (April 2026) — first-class cloud handoff makes Cursor genuinely multi-mode (local interactive + cloud delegated).
- Windsurf Claude Opus 4.7 backend — closed some of the model quality gap with Cursor 3.
- JetBrains Air productization (Q1 2026) — multi-vendor agent orchestration is now packaged rather than DIY.
The category has matured from “AI assistance in editors” to “AI-native development environments.” May 2026 is the first month where all three positions have their April releases bedded down enough to compare cleanly.
Pair with a terminal agent
JetBrains’ April 2026 research found Claude Code shares second-place AI coding tool adoption at 18% of developers worldwide. The pattern is clear: an IDE plus a terminal agent. The May 2026 pairings:
- Cursor 3 + Claude Code — the de facto two-product setup for VS Code-style developers.
- Windsurf + Claude Code — the value-conscious version.
- JetBrains Air + Junie CLI — the JetBrains-stack version with multi-model terminal flexibility.
- Any IDE + Claude Code — works regardless of which IDE you pick.
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.
- Windsurf — fewer bleeding-edge features than Cursor 3; no cloud agents on isolated VMs; community size is smaller.
- JetBrains Air — community share and third-party tooling are smaller than Cursor 3’s; some advanced JS/TS workflows are still smoother in Cursor.
Bottom line
Cursor 3 for VS Code-style developers wanting the most polished AI IDE. Windsurf for value-conscious VS Code-style developers. JetBrains Air for JetBrains-shop developers and multi-vendor model orchestration. Pick by IDE family preference; the IDE quality matters more than marginal agent feature differences. Pair whichever you pick with a terminal agent (Claude Code or Junie CLI) — JetBrains’ research data confirms the IDE-plus-terminal-agent pattern is now mainstream rather than niche. Don’t switch IDEs to chase agent features; pick the IDE that matches your stack and add a terminal agent.
