Short answer: Antigravity is free and runs Claude Opus, Cursor is the more mature editor
Verified July 31, 2026. TL;DR: Google Antigravity is $0 a month for individuals, and its model table gives that free plan Claude Opus 4.6 alongside Gemini. Cursor's paid tier starts at $20 and Claude Code has no free tier at all. If budget is the constraint, start on Antigravity. If you want the mature editor, pay Cursor. If you want a terminal agent, buy Claude Pro.
| Google Antigravity | Cursor | Claude Code | |
|---|---|---|---|
| Form | IDE, standalone agent app, CLI, and SDK | Full IDE | Terminal agent |
| Free tier | $0/mo, basic weekly rate limits | Hobby, $0 | None |
| Entry paid tier | Google AI Pro, $20/mo | Pro, $20/mo | Claude Pro, $20/mo, $17 annual |
| Top individual tier | AI Ultra, $200/mo, 20X Pro tokens | Ultra, $200/mo, 20x Pro limits | Max, from $100/mo, 5x or 20x Pro |
| What it meters | Weekly quota free, five-hour refresh plus weekly cap paid | Agent limits per tier | Rolling five-hour window plus weekly |
The free tiers are not the same free tier
Antigravity's pricing page lists "For Individuals" at "$0/month" with "Unlimited Tab completions" and "Basic weekly rate limits", and its model table checks Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b for the free plan. Read the caveat: Google's plans page files "Access to third-party models" under Ultra, and its May 19 post says non-Gemini models "remain on a separate fixed rate limit". Cursor's Hobby plan is $0 too. Claude Code has none.
The paid ladders have converged
On May 19, 2026 Google cut its top Antigravity tier "from $250 to $200" and added a $100 Ultra with "a rate limit of 5X worth of tokens compared to the $20/mo Pro plan". Cursor runs Pro at $20, Pro+ at $60 with "3x Pro limits on Agent", Ultra at $200 with "20x Pro limits on Agent". Claude Pro is $20, $17 annually, Max from $100 with "5x or 20x more usage than Pro".
Antigravity is four products, not one
Antigravity is four things: Antigravity 2.0, "a standalone desktop application" that "functions independently of an IDE", plus the CLI, the IDE and an SDK. The IDE's agent actuates Chrome for "dashboard reads, SCM actions, UI testing". Cursor ships native browser control too; Claude Code gets there through an MCP server or the separate Claude for Chrome extension. Google's own caveat: "Antigravity IDE is not supported for enterprise customers."
How to choose, in one line each
If you are spending nothing, install Antigravity and run Opus on Google's bill. If you want the mature editor with a published limit ladder, pay Cursor, and read Claude Code vs Cursor and Cursor vs Copilot. If you want an agent you point at a repo, buy Claude Pro, then compare the wider field in the Codex, Claude Code, and Copilot breakdown or Windsurf vs Cursor vs Claude Code.
