Antigravity vs Cursor
One is free and Gemini-only with an unpublished weekly cap; the other costs $20 and lets you pick your model. That is the whole trade.
Updated August 28, 2026 · Independent comparison — Google Antigravity, Cursor Pro are separate products.
Google Antigravity
Google's agent-first IDE, free in preview
Google Antigravity is an agent-first IDE available free in public preview, with editor, terminal and browser agents plus a CLI. The free tier is metered by a weekly agent quota that Google does not publish numerically, while Tab and Command completions are typically unlimited. To get more headroom you buy a Google AI plan rather than an Antigravity plan; paid tiers share one Gemini quota pool and can purchase AI credits as overage at API rates. Non-Gemini models sit on a separate, smaller limit because of capacity.
Cursor Pro
The $20 AI IDE seat
Cursor Pro is $20/month and buys two separate monthly pools: a generous one for Cursor's own models (Composer 2.5, Grok 4.6 and 4.5) and a smaller one for third-party Claude, GPT, Gemini, GLM and Kimi models metered at API list rates. Unused pool does not roll over. The defining behaviour is what happens at the ceiling: instead of stopping, Cursor offers on-demand usage billed in arrears at the same rates, and it never silently degrades your model. Yearly billing exists but Cursor does not publish the rate on its help table.
Bottom line
One is free and Gemini-only with an unpublished weekly cap; the other costs $20 and lets you pick your model. That is the whole trade. Choose Google Antigravity if free matters, and Gemini models do your work; choose Cursor Pro if you want to choose between Claude, GPT, Gemini, GLM and Kimi.

1DevToolOne window, every agent you're paying for
Whichever seat wins here, you end up locked to one vendor's harness — and most of these subscriptions are contractually barred from driving anything else. 1DevTool runs Claude Code, Codex CLI, Cline, OpenCode and Gemini CLI side by side in persistent terminals, so you can put each subscription behind the agent it's actually licensed for and switch between them without switching windows. It adds an HTTP client, a 13-engine database client and an embedded browser too. One-time $29, no subscription.
