How I Compared Three AI Code Editors Over 30 Days
To properly evaluate modern AI code editors, I fully uninstalled my long‑tuned VS Code setup and lived exclusively inside Cursor, Google Antigravity, and Windsurf for thirty days. The goal was simple: discover which AI‑first IDE actually improves daily development, not just demo scenarios. I replicated a typical full‑stack workload—bug hunting across multi‑folder projects, large refactors, and building new features from scratch—while rotating each IDE as my primary environment. I paid close attention to code generation quality, debugging assistance, agent workflows, and how well each tool integrated into an existing developer muscle memory. Instead of treating AI as a sidecar chat window, I leaned into agentic workflows: multi‑step tasks, long‑running refactors, and autonomous project work. By the end of the month, one editor consistently reduced friction, kept context intact, and helped me ship faster, while the others showed clear but more limited strengths.
Cursor: Familiar Powerhouse With Strong Codebase Handling
Cursor was the easiest transition from VS Code because it builds on the same foundation, preserving familiar keybindings and extension habits. Its standout advantage is sharp codebase indexing: tracing a bug across five different folders feels natural, with dependencies mapped clearly so you can run complex edits without losing your place. Version 3.0 pushes Cursor from “AI in a text editor” to a mission control center for autonomous development, thanks to a dedicated multi‑agent pane and an overhauled Composer system that enables parallel workflows. The cloud handoff is a genuine productivity win—start a massive multi‑file refactor on one machine, close your laptop, and resume seamlessly elsewhere. However, during very long debugging sessions, I noticed the AI sometimes fell into repetitive logic loops, indicating context degradation over time. Cursor excels at structured refactors, but its agents still need more resilience for extended problem‑solving.
Google Antigravity: Next-Gen Multi-Agent Reasoning Takes the Lead
Moving into Google Antigravity felt less like switching editors and more like stepping into a new category of AI developer tools. The interface splits into a standard Editor and an Agent Manager, and the latter is where it shines. You can spin up multiple agents that coordinate across the terminal, editor, and a built‑in browser. Instead of dumping code immediately, Antigravity first creates a detailed execution plan, waits for approval, then launches parallel agents to implement it. In one case, I had it build a real‑time finance dashboard from scratch: it planned the work, generated the code, launched the app in its browser, interacted with the charts, and even returned screenshots and recordings of the working UI. Gemini 3.1 Pro is now fast and handles huge contexts well, though it still trails Claude on deep logic and complex math. There are also performance bugs and layout quirks, especially when many agents run concurrently—but even with those flaws, Antigravity felt a step ahead in autonomous, end‑to‑end development.
Windsurf: Smooth Kanban-Style Agent Workflows, Basic Coding Intelligence
Windsurf targets AI‑native coding from a project management angle. Because it is also built on the VS Code architecture, onboarding is effortless—you keep your keybindings, layout, and mental model. Windsurf 2.0 introduces the Agent Command Center, which replaces messy linear chat logs with a Kanban‑style dashboard directly inside the IDE. Tasks are organized into columns like Running, Blocked, and Ready, so you can launch multiple agents and track progress at a glance without polluting your main editor tabs. The Spaces feature goes further by bundling agent sessions, pull requests, files, and shared context into cohesive workspaces, making larger efforts easier to manage. The catch is that its default software engineering intelligence feels basic. When I asked Windsurf to build a more complex personal website from a single prompt, it missed numerous small implementation details. It excels at orchestrating work but currently lags in raw coding depth compared with Cursor and Antigravity.
Cursor vs Windsurf vs Antigravity: Which AI IDE Should You Choose?
After a month of real projects, the Cursor vs Windsurf vs Antigravity IDE comparison shows that all three are viable VS Code alternatives—but one clearly leads. Cursor is the safest bet if you want powerful codebase understanding with minimal disruption to your current workflow. Windsurf is ideal if you care most about organizing complex efforts, thanks to its Kanban‑style Agent Command Center and Spaces, but you may outgrow its default coding intelligence quickly. Google Antigravity, despite its early‑stage performance bugs and UI rough edges, emerged as the dominant choice. Its multi‑agent system, planning‑first approach, and tight integration across editor, terminal, and browser make autonomous development feel real rather than aspirational. For developers ready to lean into AI‑driven workflows instead of just inline completions, Antigravity offers the most compelling, future‑proof experience today—especially as upcoming Gemini upgrades promise stronger logic and smoother performance.
