Quick Verdict
Decision Matrix (March 2026)
- Choose Cursor if: You need a proven, polished AI IDE with battle-tested agents, tab completion, and a massive user community. You want something that works today.
- Choose Antigravity if: You want agent-first development where AI manages entire workflows, you value Google Cloud integration, or you want free access to Gemini 3.1 Pro during preview.
- Wait and see if: You're risk-averse. Antigravity is still in public preview with limited real-world validation. Cursor is the safer bet right now.
Cursor is the market leader. It crossed $1B ARR faster than any B2B SaaS company in history, has over 1 million paying subscribers, and just raised at a $29.3B valuation. Its latest release (Cursor 2.5, Feb 2026) added long-running agents, plugins, and a marketplace.
Google Antigravity is the most ambitious challenger to enter the space. Backed by $2.4B in infrastructure spending, it takes a fundamentally different approach: instead of augmenting your coding, it delegates entire tasks to autonomous agents. Early benchmarks show its Gravity Mode completing 72% of tasks on first attempt, ahead of Cursor Composer's 64% (though behind Claude Code's 76%).
What Is Google Antigravity?
Google Antigravity is an agent-first IDE announced November 18, 2025 alongside Gemini 3. It is not another copilot-style assistant. The core design principle: you describe what to build, and agents handle the rest.
The IDE has two surfaces. The Editor View is a modified VS Code fork with AI-powered tab completions and inline commands. The Agent Manager is a mission control dashboard where you spawn, monitor, and orchestrate multiple agents working asynchronously across different workspaces.
Key Concepts
- Gravity Mode: Describe a task in natural language. The IDE generates a multi-file implementation plan, creates/modifies files, runs tests, and iterates on failures autonomously.
- Browser Subagents: Agents can launch Chrome, interact with your app's UI, take screenshots and video recordings, and verify functionality automatically.
- Artifacts: Agents produce tangible deliverables (task lists, implementation plans, screenshots, browser recordings) so you can verify their work at a glance.
- Knowledge Base: A dual-context system where agents save useful context and code snippets, improving future task performance. Knowledge Items are distilled from conversations by a background subagent.
Antigravity vs. Google's Other AI Tools
Gemini Code Assist is an IDE extension that adds AI suggestions to your existing editor. Gemini CLI is a terminal-based agent. Antigravity is a standalone agent-first IDE where AI orchestrates full workflows. They serve different levels of autonomy.

- Enterprise ($45/user/month): Private model deployment, SOC 2 compliance, admin controls
Pricing Reality Check
Antigravity's preview pricing is generous, but Google has explicitly stated it's not final. Expect changes as the product moves to general availability. Cursor's pricing is stable and well-understood after 2+ years.
Architecture: AI-Native vs. Agent-First
Cursor: AI-Native IDE
Cursor forked VS Code and rebuilt it around AI assistance. Tab completion, inline editing, chat, and agent mode are first-class features integrated into the editor. The AI has deep access to your project structure, open files, and recent changes.
Background agents (released late 2025, upgraded in Cursor 2.5) run in isolated Ubuntu VMs with internet access. You can spin up 8 parallel agents that work on separate branches and open PRs. They can test their own changes and produce videos, screenshots, and logs as proof of work. Agents are accessible from desktop, web, mobile, Slack, and GitHub.
Google Antigravity: Agent-First IDE
Antigravity inverts the control model. Instead of you coding and occasionally asking AI for help, you become the task manager. Agents plan steps, write code, run the terminal, open the browser, validate outputs, and leave behind artifacts showing what they changed.
Cloud Workstations eliminate local environment issues entirely. Builds run on Google's infrastructure: a Webpack build that takes 90 seconds on an M3 MacBook Pro reportedly completes in 11 seconds on Antigravity. Pre-configured toolchains ship for Python, TypeScript, Go, Rust, Java, and C++.
Cursor: Control + Speed
You drive. AI assists at every step with tab completions, inline edits, and agent mode. 2+ years of production iteration. Massive extension ecosystem via Cursor 2.5 Marketplace.
Antigravity: Delegation + Autonomy
You delegate. Agents manage entire workflows across editor, terminal, and browser. Cloud-native builds on Google infra. Browser subagents verify UI changes automatically.
When Cursor Wins
Production-Tested
2+ years in production. 1M+ paying subscribers. Hundreds of thousands of codebases. Cursor's reliability is proven at scale. Antigravity is months old and still in preview.
Tab Completion
Cursor's autocomplete predicts multi-line completions as you type. Developers use this hundreds of times per day. It's the feature that makes the $20/month feel like a bargain.
Ecosystem and Plugins
Cursor 2.5 introduced a plugin marketplace. The community is massive. Third-party integrations, shared workflows, and enterprise deployments are well-established.
Multi-Model Flexibility
Cursor offers Claude Sonnet 4, GPT-5.4, Gemini, and more through its credit system. No lock-in to a single provider's model family.
When Antigravity Wins
Agent-First Workflow
If you want to describe tasks and have AI execute them end-to-end, Antigravity's Gravity Mode is more autonomous than Cursor's agent. Browser subagents can verify UI changes visually.
Google Cloud Integration
Cloud Workstations, pre-configured toolchains, builds on Google infra. If your team already runs on GCP, Antigravity slots in naturally. Cloud builds are dramatically faster than local.
Free During Preview
Gemini 3.1 Pro with generous rate limits, no cost. For individual developers or startups evaluating tools, this is a real advantage while it lasts.
Knowledge Base System
Agents learn from your coding patterns through a dual-context knowledge system. Distilled Knowledge Items improve future task performance. Cursor has no equivalent persistent learning mechanism.
Decision Framework
| Priority | Best Choice | Why |
|---|---|---|
| Proven reliability | Cursor | 2+ years in production, 1M+ paying users |
| Agent autonomy | Antigravity | Agent-first architecture with Gravity Mode |
| Tab completion | Cursor | Best-in-class inline autocomplete |
| Browser testing | Antigravity | Built-in browser subagents with video recording |
| Enterprise readiness | Cursor | SSO, admin controls, established Teams plan |
| Google Cloud teams | Antigravity | Cloud Workstations, native GCP integration |
| Plugin ecosystem | Cursor | Cursor 2.5 Marketplace, large community |
| Build speed | Antigravity | Cloud-native builds on Google infrastructure |
| Cost (today) | Antigravity | Free during preview vs. $20/month for Cursor Pro |
| Cost (long-term) | Toss-up | Antigravity pricing not finalized; Cursor is predictable |
| Multi-model support | Cursor | Broader model selection with credit system |
| Learning/knowledge | Antigravity | Dual-context knowledge base for persistent memory |
Cursor is the safe choice. It works, it's fast, and it has a track record. Most developers should start here.
Antigravity is the ambitious choice. If agent-first development is the future (and Google is betting $2.4B that it is), early adopters will have an advantage. But preview-stage tools come with preview-stage rough edges. Early users report agents sometimes creating nonexistent helper files that need manual cleanup.
For precise code editing in either tool, Morph Compact Attention improves long-context accuracy. WarpGrep adds fast semantic codebase search that works as an MCP tool in both Cursor and Antigravity.
