Short answer
Pick Google Antigravity if you want to start free and are happy in Google's stack: the Individual plan costs nothing, includes unlimited Tab completions, and comes as a desktop App for running agents in parallel, the agy CLI, an IDE and extensions for other editors. Pick Cursor if you want one editor with more model families (Grok, Composer, and Claude, GPT and Gemini at API prices) plus event-driven Automations. Antigravity's strongest models, Gemini 4 Argon and Claude 5.5, need a paid Google AI plan.

Antigravity has no plan of its own to buy: individuals use it free, and a Google AI Pro or Ultra subscription raises the limits and unlocks the bigger models. Google does not publish the exact quotas. Pro's refreshes every five hours until a weekly limit, and Pro and Ultra can buy AI credits for overage. Cursor sells its own plans, with a weekly pool for Cursor's models and per-token billing for everyone else's.
What Antigravity is now
Antigravity started as an agent-first IDE and is now a family of products on one agent harness:
- The App is a desktop command center that runs several local agents in parallel, groups them into projects and sends scheduled messages. It grew out of the IDE's agent manager.
- The CLI, started with
agy, runs agents, shell commands and background subagents in the terminal. - The IDE is a full editor with Tab completions and an agent side panel.
- Extensions bring the agent to VS Code, Visual Studio, JetBrains IDEs, Zed, Xcode and Eclipse, and the CLI includes an ACP server (
agy acp) for other editors. - An SDK lets you build your own agents on the same harness in Python.
Cursor is one editor, with a CLI (agent) and cloud agents around it. If you want the agent inside JetBrains or Xcode, both have a route; Antigravity covers more editors.
Free against paid
Antigravity's Individual plan is the main reason people try it. It costs nothing and includes agent models, unlimited Tab completions and unlimited Command requests, with a quota that refreshes weekly. Google AI Pro at $19.99 a month raises the quota and refreshes it every five hours until a weekly limit is reached. Ultra, from $99.99 a month, gives five or twenty times Pro's limits in Antigravity.
Cursor's free plan has limited agent and chat requests. Plus at $8 a month covers Cursor's own Grok models from a weekly pool. Cloud agents, Automations and other vendors' models start at Premium, $30 a month.
One limit to know: Antigravity does not take your own API key. Beyond the quota, Pro and Ultra subscribers buy AI credits.
Models
On the free plan, Antigravity's model list is Gemini 3.8 Flash, plus older Claude 4.6 models and GPT-OSS-120b that are scheduled for removal on November 18, 2026. Gemini 4 Argon needs a paid Google AI Pro plan, Claude Sonnet 5.5 and Opus 5.5 are on paid plans too, and Gemini 4 Carbon is for Ultra.
Cursor's own models are Grok 4.7 and Composer 2.5. From Premium you can also pick Claude, GPT, Gemini and other models, each billed at its provider's list price, for example $2 per million input tokens and $10 per million output tokens for Gemini 4 Argon.
Hooks, scheduling and unattended work
Both are customized with rules, skills, MCP servers, subagents and plugins.
- Hooks: Antigravity has 6 events (
SessionStart,PreToolUse,PostToolUse,PreInvocation,PostInvocation,Stop) in.agents/hooks.json, with command handlers, andPreToolUsecan deny a tool call. Cursor has 21 events, with command or prompt handlers. - Scheduling: Antigravity has
/schedulefor a delayed or recurring instruction and scheduled messages in the App. Cursor's Automations start a cloud agent on a cron schedule or on events from GitHub, GitLab, Slack, Linear, Sentry, PagerDuty or a webhook. - Away from your desk: Antigravity has Remote Control, which drives desktop and CLI sessions from a browser. Cursor's cloud agents can be started and followed from Slack or your phone.

- BriefkinWe make thisBoth tools are built for running agents in parallel, which means more sessions waiting on you. Briefkin's installer adds a hook to Cursor and to Antigravity's CLI, as well as Claude Code and Codex, shows their sessions on one board, and pings you on Telegram when a Claude Code or Codex session stops for a permission.See how it works
