June 18, 2026 update: Google’s consumer Gemini CLI and Gemini Code Assist IDE-extension transition lands today. Free users, Google AI Pro users, Google AI Ultra users, and Gemini Code Assist for individuals are being moved toward Antigravity CLI and Antigravity 2.0. Gemini Code Assist Standard, Enterprise, and Google Cloud customers keep their existing access under separate enterprise rules.
Google’s agent-first coding product has become a broader agentic development platform. The current public story is no longer only a VS Code fork with Manager view. It is Antigravity 2.0 for desktop multi-agent orchestration, Antigravity CLI for terminal agents, Antigravity SDK for custom agents, and Antigravity IDE for editor workflows, all tied to the same server-side harness.
Gemini 3.5 Flash is now Google’s stated high-speed engine for agentic developer work. Agents still produce reviewable Artifacts such as task lists, implementation plans, screenshots, and browser recordings, but the sharper June 2026 buyer question is migration and quota governance: which surface should your team use, who pays for credits, and which consumer or enterprise rule applies?
System Verdict
Pick Antigravity if you want Google’s most opinionated agent-first development stack. Antigravity 2.0 manages multiple local agents in parallel across projects and workspaces. Antigravity CLI brings the same harness to terminal work. Antigravity SDK lets teams prototype custom agents and evaluations. Antigravity IDE keeps the editor, Agent Manager, Artifacts, and browser verification loop.
Skip it if you want predictable costs or a stable non-Google model/billing lane. Google now has a clearer Antigravity pricing page, but credit consumption is still not token-transparent. Claude Code remains the cleaner autonomous terminal agent if you are not buying into Google. Cursor has a more mature multi-model IDE workflow with more transparent API-rate billing.
Who pays which tier: Individual $0 for evaluation with basic weekly limits. Google AI Pro $19.99/month for developers who want larger limits and a flexible AI credit pool. Google AI Ultra $100/month or $200/month for heavier Antigravity, Gemini, media, and agent usage. Organization access now runs through Google Cloud with Google Cloud terms, project integration, and consumption-based API pricing.
What Changed Since The Last Refresh
- The product surface broadened. Antigravity is now a platform: Antigravity 2.0, Antigravity CLI, Antigravity SDK, and Antigravity IDE. The older “agent-first IDE” framing is too narrow for June 2026.
- June 18 is a migration date, not a normal release note. Google says Gemini CLI and Gemini Code Assist IDE extensions stop serving requests for Google AI Pro, Google AI Ultra, free Gemini Code Assist for individuals, and Gemini Code Assist for GitHub. Enterprise and Google Cloud customers have separate continuity rules.
- The pricing surface is clearer but still quota-sensitive. The live pricing page lists Individual at $0, Google AI Pro, Google AI Ultra, and an Organization plan via Google Cloud. The Individual plan includes Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet and Opus 4.6, gpt-oss-120b, unlimited Tab completions, unlimited Command requests, and basic weekly rate limits.
- The current changelog moved past v1.23.2. The engine changelog now shows 2.1.4 on June 11, 2026 with a redesigned quota screen, PDF attachments to Gemini messages, a
/btwside-question command, conversation search, file breadcrumbs, nested subagents, MCP stability fixes, and new sensitive-path confirmations for.vscodeand.cache. - The buyer risk moved from “preview IDE churn” to “platform migration plus credit governance.” Teams need to decide whether Antigravity is replacing Gemini CLI, Code Assist IDE extensions, both, or neither. They also need to document which users are on consumer subscriptions versus enterprise or Google Cloud access.

What it actually is
A shared Google agent harness with four user-facing developer surfaces. Antigravity 2.0 is the desktop command center for projects, workspaces, local agents, and scheduled work. Antigravity CLI is the terminal surface. Antigravity SDK is the programmatic surface for custom agents and evaluations. Antigravity IDE is the editor surface with Agent Manager, Artifacts, browser verification, and repo context.
Artifacts are the collaboration primitive. Instead of showing raw tool-call logs, agents produce structured markdown deliverables: task lists, implementation plans, screenshots of UI states, and browser recordings of verification flows. Developers comment and iterate on Artifacts like Google Docs.
The real moats are three. First, the shared harness lets Google move features across desktop, CLI, SDK, and IDE surfaces. Second, native Chrome control lets agents visually verify web-app changes in the same tool. Third, Google’s subscription and enterprise packaging can route individual developers, AI Pro users, AI Ultra users, and Google Cloud organizations through one stack.
When to pick Antigravity
- Parallel-agent workflows. Manager view spawns multiple agents on independent workspaces. One refactors auth, another builds UI, a third writes tests, all running at once under a unified review surface.
- Gemini CLI migration. If you used Gemini CLI or Gemini Code Assist IDE extensions as a free, Pro, Ultra, or individual user, Antigravity CLI is the official migration path after June 18, 2026.
- UI work that needs visual verification. The integrated Chrome lets agents click through the running app, take screenshots, and record flows. Artifacts capture the evidence so you review what the agent actually saw.
- You’re on the Google AI Pro or Ultra bundle already. Antigravity folds into Google’s AI subscription stack, now centered on AI Pro $19.99 and Ultra tiers starting at $100.
- You need SDK-level agent experiments. The SDK gives teams a way to prototype custom agents, automate engineering tasks, and run evaluations on the Antigravity harness.
- Architectural planning before coding. Agents map a full architectural plan as an Artifact before touching code, then produce reviewable screenshots, plans, and recordings.
- Chrome extension or web-app development. Native browser control collapses the build-test-fix loop into one tool.
When to pick something else
- Pure terminal or autonomous agent loop: Claude Code. Stronger CLI agent with cleaner autonomous iteration on test failures.
- GUI-first multi-model IDE with transparent billing: Cursor. API-rate billing, $20 Pro, no credit opacity.
- VS Code fork with multi-provider model choice: Windsurf. Cascade agent, Cognition-owned, cleaner pricing after March 2026 repricing.
- Open-source agent inside stock VS Code: Cline or Continue. Bring-your-own-key, no editor fork.
- Budget VS Code coding assist: GitHub Copilot. $10/mo, less integrated, single-file focus.
- Fully autonomous remote coding agent: Devin. Runs in a cloud sandbox with no editor.
- Open-source, editor-agnostic pair programmer: Aider. Git-native terminal workflow.
Pricing
Antigravity packaging now combines the Antigravity pricing page with Google AI subscription pricing:
| Plan | Price | Usage | Who’s it for |
|---|---|---|---|
| Individual | $0 | Basic weekly rate limits, unlimited Tab completions, unlimited Command requests | Evaluation and light development |
| Google AI Pro | $19.99/mo | More generous Antigravity limits and flexible AI credit pool | Most individual developers land here |
| Google AI Ultra | $100/mo | 5x higher usage limit in Gemini app and Antigravity than Pro | Power users testing sustained agent workflows |
| Google AI Ultra top tier | $200/mo | 20x higher usage limit in Gemini app and Antigravity than Pro | Sustained multi-agent and media-heavy workloads |
| Organization via Google Cloud | Consumption based | Google Cloud terms, project integration, Gemini Enterprise Agent Platform path | Teams that need enterprise procurement and Cloud billing |
Prices and I/O changes verified 2026-06-18 via Google Antigravity pricing, Google AI subscriptions, Google’s May 19 subscription update, and Google’s Gemini CLI transition post.
Credit opacity warning: Google does not publish the credit-to-token conversion rate. Community reporting in March 2026 flagged AI Pro subscribers hitting weekly rate limits at a fraction of their prior daily quota. Budget-sensitive workloads should benchmark their own weekly consumption before committing.
Against the alternatives
| Antigravity AI Pro $20 | Cursor Pro $20 | Claude Code (via Claude Max $100) | |
|---|---|---|---|
| Default model | Gemini 3.5 Flash for I/O 2026 agentic workflows | Opus 4.8 / OpenAI frontier models / Gemini 3.5 Flash | Opus 4.8 |
| Multi-agent surface | Manager view with parallel agents | Agents Window (3.0+) | Single terminal agent |
| Browser control | Native Chrome integration | Design Mode (browser preview) | None |
| Artifacts / deliverables | Structured markdown, screenshots, recordings | Diffs, PRs, worktrees | File writes, terminal logs |
| Billing model | Opaque credits | API-rate usage pool | Flat monthly |
| Editor integration | VS Code fork | VS Code fork | Terminal-first |
| Best viewed as | Google-stack agent IDE with parallel orchestration | Generalist multi-model IDE | Strongest autonomous CLI agent |
Failure modes
- Credit-to-token ratio is undisclosed. Google does not publish how credits convert to Gemini tokens. Users report unpredictable consumption, especially on long-context runs.
- March 2026 quota cuts hit existing subscribers hard. AI Pro users reported hitting weekly limits at under 9M input tokens, versus 300M+ weekly before the cut. Refresh cycle moved from 5 hours to weekly.
- VS Code lock-in. Antigravity is a full editor fork. JetBrains, Vim/Neovim, Zed, and Emacs users have no entry path.
- Model lineup shifts without migration paths. Both Gemini 3 Pro High and Low were pulled from Antigravity when 3.1 Pro launched, leaving active sessions to prompt for a manual model switch.
- Migration is not 1:1. Google says Antigravity CLI will not have exact Gemini CLI feature parity at launch, even though it keeps Agent Skills, Hooks, Subagents, and Extensions as Antigravity plugins.
- Public surface is changing quickly. Antigravity moved from the original IDE preview to 2.0, CLI, SDK, organization access, and a 2.1.4 engine release in less than a month.
- Old tutorials age fast. v1.21.6 already formalized Manager deprecations, and 2.0 changes the recommended mental model again.
- Browser automation is Chrome-only. Firefox, Safari, and Edge testing require external tooling.

FAQ
Is Antigravity free to use? Yes, for individuals. The live pricing page lists an Individual $0 plan with basic weekly rate limits, unlimited Tab completions, unlimited Command requests, and access to Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet and Opus 4.6, and gpt-oss-120b. Paid tiers use Google AI Pro and Google AI Ultra, while organizations use Google Cloud.
What changed in May-June 2026?
Google I/O 2026 introduced Antigravity 2.0, Antigravity CLI, Antigravity SDK, organization access, Gemini 3.5 Flash, and a new pricing surface. On June 11, engine version 2.1.4 added a clearer quota screen, PDF attachments, /btw, conversation search, nested subagent visibility, MCP stability fixes, and new sensitive-path confirmations.
How is Antigravity different from Cursor or Windsurf? All three have AI coding agents, but Antigravity now reaches beyond the editor. It is a Google platform with desktop orchestration, CLI, SDK, IDE, browser verification, Gemini subscriptions, and Google Cloud organization access. Cursor is broader on model choice and has more transparent API-rate billing. Windsurf sits between them with Cascade and cleaner credit accounting.
Does Antigravity support Claude Opus 4.8? Not on the live pricing page as of June 18, 2026. The published model line lists Claude Sonnet and Opus 4.6, alongside Gemini 3.5 Flash, Gemini 3.1 Pro, Gemini 3 Flash, and gpt-oss-120b. Recheck the live model picker before making procurement decisions.
Do Gemini CLI users have to migrate? For consumer/free/Pro/Ultra usage, yes. Google says Gemini CLI, Gemini Code Assist IDE extensions, and Gemini Code Assist for individuals stop serving those requests on June 18, 2026. Gemini Code Assist Standard, Enterprise, Google Cloud, and Gemini Enterprise Agent Platform paths have separate continuity rules.
