Google Antigravity

A Tier · 8.0/10

Google's agent-first AI IDE -- deploys up to 5 autonomous coding agents in parallel on a VS Code fork. Antigravity 2.0 (I/O 2026) is the runtime substrate for Gemini Spark, and the Antigravity CLI is now the official successor to Gemini CLI, which stopped serving consumer tiers on 2026-06-18

Last updated: 2026-06-18Free tier availablePowered by Gemini 3.5 Flash / Gemini 3.1 Pro / Claude Opus 4.6 / GPT-OSS 120B (multi-model). Gemini 3.5 Flash added at I/O 2026 (2026-05-19) and is the model behind the antigravity-preview-05-2026 Managed Agent.

The Good and the Bad

What we like

  • +Up to 5 autonomous agents working in parallel on different parts of your project -- genuinely unique multi-agent architecture
  • +Mission Control Manager View lets you dispatch, monitor, and coordinate agents like an air traffic controller
  • +Built-in Chrome browser for testing means agents can see and interact with your running app, not just write blind code
  • +Multi-model support: Gemini 3.1 Pro, Claude Sonnet/Opus 4.6, and GPT-OSS 120B -- switch models per task
  • +MCP (Model Context Protocol) support connects agents to GitHub, databases, and external APIs
  • +Built on VS Code fork so the editor is familiar -- extensions and keybindings carry over

What could be better

  • Free tier was gutted -- dropped from 250 to 20 daily requests (92% reduction), sparking community backlash
  • Credit system is opaque -- you can't predict how many credits a task will consume, making cost planning impossible
  • Ultra at $249.99/mo is the most expensive AI coding tool available -- hard to justify over Cursor + Claude Code combined
  • Agent coordination adds complexity -- managing 5 parallel agents requires a mental model most developers aren't used to
  • Pricing protests from The Register and developer forums suggest Google may change pricing again, creating uncertainty
  • Lock-in risk: it's a Google-specific IDE fork, not a plugin you can add to any editor

Known Issues

  • GEMINI CLI SUCCESSOR -- CUTOVER NOW LIVE (2026-06-18, TODAY): Google designated the **Antigravity CLI** as the official replacement for Gemini CLI and the Gemini Code Assist IDE extensions, and as of today the consumer-tier cutover has taken effect -- Gemini CLI has stopped serving requests for Google AI Pro/Ultra and free Code Assist for individuals (enterprise Standard/Enterprise license holders keep Gemini CLI). Antigravity CLI is available to everyone now. Google states 'there won't be 1:1 feature parity out of the gate' but it keeps the most critical Gemini CLI features -- Agent Skills, Hooks, Subagents, and Extensions (now as Antigravity plugins). This makes Antigravity not just an IDE/runtime but Google's primary command-line agent surface for consumers. If you were scripting against `gemini` on a consumer plan, migrate now.Source: Google Developers Blog (developers.googleblog.com/en/an-important-update-transitioning-gemini-cli-to-antigravity-cli/), 9to5Google · 2026-06-18
  • I/O 2026 SHIP (2026-05-19): ANTIGRAVITY 2.0 announced at Google I/O 2026. Vendor blog post 'Introducing Google Antigravity 2.0' published on DeepMind / Google's I/O developer recap. Concurrent ship in the Gemini API: a Managed Agents preview model `antigravity-preview-05-2026` -- the general-purpose Antigravity Agent, the first Google-hosted managed-agent endpoint. Antigravity is now also the runtime substrate for Gemini Spark (Google's new proactive 24/7 personal agent), which means Antigravity has been promoted from a standalone IDE to the underlying agent execution layer for consumer Gemini features. Specific feature deltas vs Antigravity 1.x not yet captured in this sweep -- next review should pull the full announcement post once it's published in fully indexable form.Source: deepmind.google blog 'Introducing Google Antigravity 2.0' (vendor-primary), ai.google.dev/gemini-api/docs/changelog 2026-05-19 (antigravity-preview-05-2026 Managed Agent release), gemini.google/overview/agent/spark/ (Spark runs on 'Gemini 3.5 Flash and Antigravity') · 2026-05-19
  • Free tier daily requests slashed from 250 to 20 in early 2026, and Pro tier quota refresh changed from every 5 hours to weekly for most modelsSource: The Register, Reddit r/google_antigravity · 2026-03
  • Credit consumption per task is unpredictable -- developers report identical tasks consuming wildly different credit amountsSource: Reddit r/google_antigravity, Hacker News · 2026-03
  • Agent sessions can stall or lose context on long-running tasks, requiring manual intervention and wasting creditsSource: Reddit r/google_antigravity · 2026-04

Best for

Developers working on large, multi-file projects who want to parallelize their workflow. If you regularly work on 3-5 tasks simultaneously (fix a bug, add a feature, write tests, refactor), Antigravity's multi-agent architecture is unmatched.

Not for

Solo developers on a budget (the free tier is nearly useless after the cuts), anyone who values pricing transparency, or developers who prefer lightweight tools over full IDE replacements.

Our Verdict

Google Antigravity is the most ambitious AI coding tool on the market -- 5 parallel agents, built-in browser testing, multi-model support, and MCP integration. When it works, it's like having a team of junior developers. But Google's aggressive pricing changes (gutting the free tier, introducing opaque credits) have damaged trust. At $20/mo Pro it's competitive, but the credit system means your actual costs are unpredictable. If Google stabilizes the pricing, this could be the best AI IDE available. Right now, the value score drags it down.
