Google Antigravity vs Cursor (2026): Is Google's Free Agentic IDE Worth the Switch?

Google Antigravity is free, agent-first, and the most credible reason in years to leave Cursor. It is also the one that quietly throttles you mid-afternoon and shipped a critical security hole in its first quarter. Here is the real call for 2026.

The verdict in one line

Pick Google Antigravity if you want to run autonomous agents at zero cost and you are willing to supervise them and live with a weekly usage cap. Pick Cursor if you want a polished editor that keeps you in flow, predictable limits that refresh continuously, and you will pay $20 a month for that calm.

Both are forks of VS Code, so the editor underneath feels familiar either way. The split is about posture. Antigravity assumes an agent does the work and you review the result. Cursor assumes you are still driving, with an agent riding shotgun. For a founder validating an idea on a budget, Antigravity's free agent power is hard to argue with. For someone shipping to production every day, Cursor's predictability is usually worth more than the saved $20.

If you only read one section, read the rate-limit math further down. It is the thing that flips this decision for most people, and it is the thing the spec sheets bury.

At a glance

Everything in that table is from each vendor's live page as of this writing. The rest of this piece is why those numbers matter and which one is right for the way you actually build.

Google Antigravity, the agent-first bet

Google Antigravity is Google's free, agent-first development platform, and the headline is exactly that: free. Not a trial, not a preview anymore. The pricing page now lists it as "Generally Available" at $0 a month for individuals, with no credit card.

The thing that makes Antigravity different from a normal IDE is the Agent Manager: a control center where you launch multiple coding agents and let them run in parallel across your codebase, terminal, and browser, each producing "artifacts" (a task plan, a screenshot, a diff) so you can see what it did before you trust it. An agent here is just an autonomous worker you hand a task to ("add Stripe checkout to the settings page") instead of typing every line yourself. There is also a terminal-first CLI for running those agents from the keyboard, and a small Python SDK if you want to build custom agents on the same underlying agent runtime.

What you get on the free tier is genuinely generous on paper: unlimited Tab completions (the autocomplete that finishes your line), unlimited command requests, and agent access to a real model lineup, Gemini 3.1 Pro and Gemini 3.5 Flash plus Claude Sonnet and Opus 4.6 and the open gpt-oss-120b. Being able to point Anthropic's Opus at your code inside a free Google tool is the kind of thing that did not exist eighteen months ago.

Here is where the gloss comes off, and it is two specific walls.

The second wall is harder to wave away. In its first months, Antigravity became a magnet for security researchers, and they found things. Google patched a critical prompt-injection flaw (disclosed January 7, fixed late February) where a poisoned file could slip past the tool's "Strict Mode" and get the agent to execute code, reported by The Hacker News and Dark Reading. Separately, Mindgard showed a malicious "trusted workspace" could plant a persistent backdoor. None of this is unique to Google, it is the new reality of handing an autonomous agent your shell, but it is a real reason to keep Antigravity away from anything sensitive until you trust the workspace and to read what an agent proposes before you approve it.

1. 1

   Download and open a project

   Grab the build for your OS from antigravity.google and open an existing repo. The editor will feel like VS Code because it is a fork of it, your extensions and keybindings mostly carry over.

2. 2

   Open the Agent Manager

   Instead of chatting in a sidebar, you hand a task to an agent: "wire up email/password auth with Supabase." Watch it work in the Agent Manager and read the artifact it produces before approving the diff.

3. 3

   Cap the blast radius

   Keep secrets out of the workspace, review file writes, and do not point it at production credentials until you have seen how it behaves. The autonomy is the feature and the risk at the same time.

Cursor, the polished daily driver

Cursor is the agentic IDE most builders already reach for, and it earns that the boring way: it is the most in-flow, least-friction editor in the category. The agent is good, Tab completion is excellent, and the whole thing stays out of your way while you actually write. It is also a VS Code fork, so the switch from a plain editor costs you nothing.

The pricing is a clean ladder, and unlike Antigravity it is all Cursor's own, not a separate Google subscription bolted on:

• Hobby: free, no credit card, limited agent requests and limited Tab completions. Enough to try it, not enough to live in.
• Pro: $20/mo, extended agent limits, cloud agents, and Bugbot (its automated code reviewer) on usage-based billing. This is the tier almost everyone is on.
• Pro+: $60/mo, the same features as Pro with roughly 3x the usage credits. Pure headroom, no new toys.
• Ultra: $200/mo, around 20x Pro's credits and priority access to new features, for people who live in the editor all day.
• Teams: $40/user/mo, with centralized billing, team-wide Bugbot code reviews, shared cloud agents, usage analytics, and a team privacy mode.

The wall here is cost shape, not a hard cap. Every plan includes a set amount of model usage, and once you cross it, on-demand usage is billed in arrears, meaning you keep working and get charged after the fact. That is convenient until an agent-heavy week produces a bill you did not see coming. Cursor is predictable in its limits and unpredictable in its overage, which is the inverse of Antigravity's "free but throttled" problem.

The rate-limit math nobody screenshots

This is the section that should decide it for you, and it is the one a quick feature-by-feature glance misses entirely, because the two tools cost almost the same and differ on something a spec table never shows: how often your usage resets.

The two tools fail in opposite directions. Antigravity is free but throttled: the moment you do real work on the free tier, you are spending against a weekly bucket, and when it is empty you wait, sometimes days. Through early 2026 this got worse before it got better, Google cut Antigravity's quotas several times with little notice as demand spiked, and developers reported hitting caps mid-workday and multi-day lockouts (AndroidCentral tracked the changes). The 2.0 release moved to a more predictable five-hour refresh on paid plans, but the free tier is still weekly.

Cursor is paid but smooth: $20 buys a continuous credit refresh that, for most people, simply does not run out during a normal day, and if it does, you keep going on metered overage instead of hitting a wall.

So the real comparison is not "free vs $20." It is:

• Free Antigravity = $0, but plan your heavy agent runs around a weekly bucket and expect to occasionally wait.
• Antigravity + Google AI Pro = $19.99/mo for the five-hour refresh, which is the apples-to-apples match for Cursor Pro.
• Cursor Pro = $20/mo, no weekly bucket, overage billed after the fact.

At the tier where you are actually shipping daily, the two cost within pennies of each other. Which means the decision is not about money at all. It is about whether you want agent-first autonomy (Antigravity) or in-flow control with continuous limits (Cursor). The free Antigravity tier only wins outright when your usage is light enough to never hit the weekly cap.

And the rest of the field

Antigravity and Cursor are the head-to-head, but "what's better than Cursor" has more than two answers, and the right one depends on where you work. A quick, honest map of the field so you can place the two main tools against it:

• Claude Code: Anthropic's terminal-first agent. No editor, you live in the shell, and it is exceptional at large multi-file changes and reading a whole codebase. It rides your existing Claude subscription (the standard $20/mo tier gets you in). Best for engineers who already prefer the terminal. See the deeper take in Claude Code vs Cursor.
• OpenAI Codex: the same shape from OpenAI, a terminal and cloud agent bundled into a ChatGPT subscription (again, the standard $20/mo tier). Good if you are already in the OpenAI ecosystem and want agents that run tasks in the background.
• GitHub Copilot: the cheapest serious entry: Free (2,000 completions/mo), Pro $10/user/mo, Pro+ $39/user/mo. Less autonomous than the agent-first tools, but if you live in VS Code and mostly want great completion plus a capable agent for $10, it is the value pick. The full breakdown is in Cursor vs GitHub Copilot.
• Windsurf: another agentic IDE, Free, Pro $20/mo (with free use of its own SWE models and open-source models), top tier $200/mo. Cursor's closest like-for-like rival.
• AWS Kiro: the spec-driven option: you write a spec, it builds against it. Free tier plus paid. Best when you want structure and traceability rather than free-form vibe coding.

If none of these is obviously your pick after this, the wider roundup of Cursor alternatives walks the whole field.

Who should pick what

The decision rule: if your build is bursty and budget is the hard constraint, start on free Antigravity and supervise it. The day a weekly lockout costs you more than $20 of momentum, move to Cursor Pro (or pay $19.99 for Antigravity's five-hour refresh). Do not pay for polish before you feel the pain of going without it, and do not stay free once the throttle is costing you real time.

Is Antigravity just Cursor with a Google logo?

No. Both are forks of VS Code, so the editor feels similar, but the posture is different. Antigravity is agent-first: its Agent Manager runs multiple autonomous agents in parallel and produces artifacts you review. Cursor keeps you in the editor with an agent assisting. You will feel the difference within the first hour.

Is Antigravity worth using?

For free, agent-heavy work where you can supervise the agent, yes. The free tier gives you real models (including Claude Opus 4.6) at $0. The catch is the weekly rate cap and a security record worth respecting, keep it off sensitive code until you trust the workspace.

What's better than Cursor?

It depends on the job. On cost, free Antigravity. In the terminal, Claude Code or Codex. On price-for-completion, GitHub Copilot at $10. Cursor is still the best all-rounder for in-flow daily shipping, which is why it is the default.

Is Cursor AI better than Antigravity?

For predictable, in-flow daily shipping with limits that refresh continuously, yes. For zero-cost autonomous agents you are willing to babysit, no. At the paid tier where you ship daily, they cost within pennies of each other, so pick on posture, not price.
