I’ve shipped production code through Cursor, Claude Code and Google’s Antigravity in the last six months. They’re not the same tool with different logos — each represents a meaningfully different bet on what an “AI IDE” should be in 2026. Hands-on comparison from someone who codes for money.

Cursor — the IDE-first bet

Cursor is VS Code with AI woven through the editor surface. Tab-complete on steroids, agent mode for multi-file changes, deep file-level context. It’s still the most natural fit if your mental model is “I’m coding, with AI helping.” Pricing is reasonable, the team ships fast, the ecosystem of extensions is solid.

Where it shines: keyboard-driven coding flow, polished diff UX, fast on big repos. Where it falls short: Cursor’s agent mode is competent but not the strongest in 2026.

Claude Code — the agent-first bet

Anthropic’s terminal-native take. The mental model is reversed: the agent is the interface; you guide it. Run claude in a project, give it tasks in natural language, watch it edit files, run tests, commit. Power users live in this; newcomers find it disorienting.

Where it shines: large refactors, anything multi-step, autonomous test-loop work. Where it falls short: not the right fit if you want to keep your hand on every keystroke.

Antigravity — the workspace bet

Google’s entry. Halfway between Cursor and Claude Code, with multi-pane workspace orchestration and tight Gemini integration. Strongest on Google-stack work (Vertex, Cloud Run, Firestore). Newer than the other two; rough edges on bespoke stacks.

The pattern that emerged for me

I use all three, for different work:

  • Cursor — UI work and small-scope edits where I want fingers on keys
  • Claude Code — refactors, multi-file changes, autonomous test loops
  • Antigravity — anything tight to Google Cloud

What this means for founders

Stop picking one. The right answer in 2026 is to be fluent in 2–3 of these and switch based on task. The IDE wars aren’t winner-take-all the way the model wars were; the surface area is too varied.

The deeper shift

The IDE is becoming an orchestration layer over many models. By 2027, expect to choose between Claude, GPT, Gemini and open weights inside the same IDE per task. The companies that win will be the ones with the best agentic UX, not the best model.
