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
Score Breakdown
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.

Alternatives to Google Antigravity
GitHub Copilot
AI code assistant that lives in your editor -- autocomplete on steroids, now with the broadest model picker of any coding tool. **Three frontier models landed in four days: Claude Fable 5.1 (2026-09-01), Gemini 3.8 Flash (2026-09-03) and GPT-6 Astra (2026-09-04)** -- Astra and Gemini auto-enable under default model enablement, but **Fable 5.1 is OFF by default because it requires data retention** to run Anthropic's safety classifiers. **A four-model deprecation slate hits 2026-10-02** (Gemini 3.5/3.6 Flash, Kimi K2.7 Code, Claude Opus 4.7), and **Business/Enterprise card/PayPal customers move to upfront per-seat charging on 2026-10-01**. **Gemini 3.7 Flash landed 2026-08-13 and Grok 4.6 on 2026-08-14**, both across Pro, Pro+, Max, Business and Enterprise and both still off by default for orgs. **Claude Opus 5 landed 2026-07-24** (Pro+, Max, Business, Enterprise) and **Grok 4.5 on 2026-07-28** (all five paid SKUs, up to 500K context, text and image input, low/medium/high reasoning effort). Both bill usage-based at provider list price, and both are off by default for Business/Enterprise until an admin enables the policy -- though that posture flips on **2026-08-26**, when new GA models covered by GitHub's data-retention agreement start auto-enabling for orgs. **MAI-Code-1.1-Flash landed 2026-08-11** (native vision, 0.25x premium-request multiplier, 73% below the model it replaces; automatic for Free/Student, manual elsewhere, off by default for orgs) and **MAI-Code-1-Flash retires 2026-09-10**. **GitHub Models (the separate free playground) was fully retired 2026-07-30.** Usage-based billing went live 2026-06-01 with AI Credits and token metering; code completions are still free; new signups for Student/Pro/Pro+/Max remain PAUSED
Cursor
AI-native code editor, agent-first in Cursor 3 -- **now a SpaceX subsidiary as of 2026-08-14, when the April acquisition option closed**. **OpenAI is cutting it off: on 2026-08-28 OpenAI notified SpaceX it will wind down the contract supplying OpenAI models to Cursor, proposed shutoff 2026-11-12, and says it is providing no future models to Cursor in the meantime** -- so the model-neutrality pitch is narrowing. Still home to **Grok 4.6 on day one (2026-08-12)**, following the Grok 4.5 model Cursor trained jointly with SpaceXAI on trillions of Cursor tokens (still $2/$6 per 1M, fast variant 2x, desktop/web/iOS/CLI/SDK), with Composer 2.5 as the fast lower-cost tier. Since 2026-08-11 the **Cursor Ultra and Teams Premium tiers also entitle you to xAI's Grok Bot**
Devin Desktop (formerly Windsurf)
Windsurf is now **Devin Desktop** -- Cognition retired the Windsurf brand via OTA update on June 2, 2026. Same editor, plans, pricing, settings, and extensions; the bundled agent is now 'Devin Local' and Devin Cloud agent access starts on the $20 Pro plan. Agent Command Center, Spaces, and Devin Review all carry over
Tabnine
AI code completion that runs locally and keeps your code private -- the enterprise-friendly alternative to Copilot
Claude Code
Anthropic's terminal-based coding agent that reads your whole repo and makes real changes -- not just suggestions. v2.1.131 (2026-05-06 Code with Claude conf) shipped Code Review GA + Remote Agents + CI Auto-Fix + Routines, plus 2x rate-limit increase from the SpaceX compute deal. **Claude Fable 5.1 (2026-09-01) is the new top model and defaults to High effort in Claude Code specifically** -- Medium on every other Anthropic surface -- at an unchanged $10/$50 per 1M with cache reads cut 4x to $0.25/MTok
Lovable
Describe the app you want in plain English and watch it build itself -- $500M ARR (June 2026) and ~1M new projects/week say it works
Devin
The most autonomous AI coding agent -- now a full product family: Devin Cloud, **Devin Desktop (the renamed Windsurf IDE, June 2 2026)**, and Devin Review. Cognition raised $1B+ at a $26B valuation (May 27). Recent shipments: **day-one support for both Claude Fable 5.1 (2026-09-01) and GPT-6 Astra (2026-09-03)** -- Cognition says it moved Devin's Opus 5 traffic to Fable 5.1 on launch day because the new cache-read pricing made a Fable-class model economical for code review. Claude Fable 5 support day-one (6/9), Auto-Triage (5/18), Windows VMs (5/21), Android Emulator (5/13)
Replit
Cloud IDE with an AI agent that can build full apps from prompts. **Agent 4 shipped May 2026** with parallel task execution (Replit reports automatic merge-conflict resolution ~90% of the time) -- coding optional, but recommended
Codex (OpenAI)
OpenAI's coding agent -- parallel tasks, PRs, and as of 2026-07-09 merged into the unified ChatGPT desktop app (Chat + Work + Codex, every plan incl. Free) with GPT-5.6 across the lineup. **GPT-6 Astra arrived 2026-09-03 with a rewritten Codex harness -- OpenAI claims 1.9x faster task completion vs GPT-5.6 Sol on Mind2Web**, though that figure combines the harness change with the model. GPT-5.4 and 5.4-mini left Codex on 2026-08-31
Codestral 2 (Mistral)
Mistral's dedicated code model -- Codestral 2 (launched 2026-04-08) relicensed under Apache 2.0, removing the commercial-use restrictions of the original. 22B dense, strong FIM (fill-in-middle), available via Mistral API + Hugging Face
Roblox Assistant
Roblox Studio's agentic AI that plans, builds, and playtests games. Planning Mode (2026-04-16) + Mesh Generation + Procedural Models brings 3D-native creation to 70M+ daily creators
