Google Antigravity
Google's agentic IDE (desktop, CLI, and SDK) with multi-model support, MCP, and a built-in browser.
Google Antigravity is an agentic IDE spanning desktop, CLI, and SDK with multi-model support, MCP, and a built-in browser. In public preview since November 2025 and now at 2.0, it absorbs the retired Gemini CLI; it's free with Pro at $20/month and Ultra roughly $100–250/month.

In practice
You want an agentic coding tool that works in the editor, the terminal, and your own scripts. Google Antigravity spans desktop, CLI, and an SDK, so the agent meets your workflow.
An agent that can't see the running app guesses at front-end work. Antigravity has a built-in browser, so it can observe and act on what it builds.
You don't want to be tied to a single model in your IDE. Antigravity supports multiple models and MCP, so you connect the tools and models you choose.

Recent platform changes
Google Antigravity added support for defining custom agents using standard Markdown format via an agent.md file. The release also introduces progressive streaming for the codesearch command, an optional index argument for copy, and default read access to the system temporary directory.
Bears on: Agent capability
View sourceGoogle added new controls for model reasoning effort by introducing a dedicated effort command and launch flag. The platform also introduced stable model slugs for consistent sessions, subagent model configuration options, and a redesigned model picker.
Bears on: Agent capability
View sourceSecurity researchers disclosed a sandbox escape vulnerability where the Antigravity agent could write a file that a trusted external tool would execute to bypass the sandbox entirely. Google acknowledged the risk of these indirect prompt injections and rolled out patches to address the issue.
Bears on: Security / enterprise
View sourcePricing
$20/mo
hybrid
Included quota
AI Pro ($20/mo, entry paid): higher rate limits than Free, all models (Gemini/Claude/GPT), and priority agent processing. Free is ~20 requests/day (cut from 250 at launch).
What is public
Antigravity's access is bundled into Google AI (Google One) subscription tiers: Free/Individual ($0, heavily rate-limited), AI Pro $20/mo, AI Ultra $100/mo (~5x Pro quota), and top-tier AI Ultra $200/mo (~20x Pro quota, cut from $250 at I/O 2026). A cheaper AI Plus tier also grants expanded limits. Pro/Ultra include multi-model access (Gemini, Claude, GPT). Enterprise is via Google Cloud's Gemini Enterprise Agent Platform (contact sales).
Billing mechanics
Flat monthly subscription per tier sets your quota (rate limits / usage allotment). Each tier bundles Gemini-model usage; AI credits act as a pay-as-you-go OVERAGE mechanism once the plan quota is hit (credits were removed from base plans in May 2026 and base entitlements raised). Heavy frontier-model use (e.g., Claude Opus) burns quota fast and can trigger multi-day lockouts on lower tiers.
Cost watchouts
Opaque credit-to-token value (undocumented), frontier-model usage burning quota fast, multi-day lockouts reported on Pro/Ultra, free-tier limits repeatedly cut, credit top-ups
Variable cost rationale
Subscription is flat, but opaque quotas plus credit overage on heavy frontier-model use make real spend hard to predict
Additional watchouts
Pricing has been volatile — free quotas slashed and a credit system introduced; cost predictability is the main developer complaint
Overage / add-ons
Once plan quota is exhausted, agent tasks stop until refresh (e.g., every 5 hrs on Free) OR you enable AI-credit overages. Credits are ~$0.01 each, bought in bulk ($25/2,500 or $199/20,000); Pro/Ultra subscribers can buy PAYG top-up credits.
Sales call required
No, self serve available
Free / trial
Free tier
Lowest paid plan
Free; Pro $20/mo; Ultra ~$100–250/mo
Commercial notes
Top Ultra cut from $250 to $200 (May 2026); a new $100 mid Ultra added; Ultra bundles 20TB storage + YouTube Premium; Antigravity CLI replaced the Gemini CLI (June 18, 2026)
Key ambiguities
Google doesn't publish how many tokens/requests one credit buys, per-model credit costs, or the exact included credit/quota amounts per tier; 'rate limits are not guaranteed'
Cancellation / refund
Monthly Google AI subscriptions, cancel anytime; refund terms per Google One; pricing has changed repeatedly (free-tier cuts, Ultra restructure)
Support SLA / resale
Higher tiers add priority access and extended agent sessions; enterprise support via Google Cloud / Gemini Enterprise Agent Platform
Missing data
Per-tier included credit/quota amounts, credit-to-token conversion, and per-model credit costs are not publicly documented
