Antigravity IDE

Google's Gemini-centered agentic development platform that combines Antigravity 2.0, Antigravity CLI, a shared agent harness, artifacts, browser previews, and terminal approval controls.

Pricing: Limited free access may vary
Platforms: IDE, Google account, Gemini
Website: https://antigravity.google
Free access note: Public preview access may be available for personal Gmail users, with model and quota limits that can change.
Caveat: Verify the current official terms, region availability, Gemini model access, and quota before treating it as a team tool.

Verdict for 2026

Antigravity has moved from “interesting Google-side IDE signal” to a real product category to evaluate: an agentic development platform built around Gemini, editor work, task management, browser/app preview, terminal approvals, and reviewable artifacts.

My take: I would not replace a mature daily Cursor or Claude Code setup with Antigravity blindly, but I would absolutely include it in a 2026 AI coding tools trial if your team already trusts Gemini models. Its value is not autocomplete. Its value is whether the Manager Surface and Artifacts make agent work easier to supervise than a long chat thread.

What It Actually Is

Google describes Antigravity as an agentic development platform. The practical difference from a normal IDE assistant is the workflow surface: you still have an editor, but the tool is also designed around managing agents, reviewing their work, and inspecting artifacts such as plans, diffs, screenshots, and command output.

The official materials emphasize an Editor View for code work, a Manager Surface for higher-level agent coordination, Artifacts for review, Fast mode and Planning mode, browser/app interaction, terminal command controls, and Gemini model access. That makes Antigravity closer to “IDE plus agent operating layer” than “VS Code with a chat panel.”

Latest Features Worth Tracking

Manager Surface for supervising agent tasks instead of burying everything in one chat timeline.
Artifacts that make plans, implementation evidence, browser state, diffs, and logs easier to review.
Editor View for familiar code reading and editing.
Fast mode for quicker execution and Planning mode for more deliberate work.
Browser/app preview for UI and web-app tasks.
Terminal approval controls so command execution is visible rather than implicit.
Gemini-centered access, including preview-style free access that should be checked against the current account and region limits.

What Changed Recently

The important recent shift is that Antigravity is no longer only an experimental IDE story. Google is positioning Antigravity 2.0, Antigravity CLI, and a Shared Agent Harness as one agent platform. That matters because it makes Antigravity a bridge between editor work, terminal automation, and cloud-style agent orchestration.

Antigravity 2.0: the IDE surface is moving toward a full agent-first workflow, not just a Gemini chat sidebar. The product story now centers on agent coordination, artifacts, app/browser observation, and reviewable work.
Antigravity CLI: Google says the CLI is designed for async coding, running multiple agents in parallel, and automating tasks that previously sat in Gemini CLI. It is written in Go and is meant to work in familiar terminal workflows.
Shared Agent Harness: the strongest architectural signal is shared runtime behavior across IDE and CLI. If the same concepts power both surfaces, teams can evaluate policies, artifacts, prompts, and agent behavior once instead of treating each UI as a different product.
Gemini CLI transition: Google says Gemini CLI will stop serving free-tier, Google AI Pro, and Ultra requests on June 18, 2026, and those users should migrate to Antigravity CLI. Enterprise, Google Cloud, Gemini Code Assist Standard/Enterprise, and paid Gemini / Gemini Enterprise Agent Platform API key paths remain supported in Gemini CLI.
Critical Gemini CLI features preserved: Google says Antigravity CLI carries forward Agent Skills, Hooks, Subagents, Extensions as plugins, and MCP. My read: this makes Antigravity CLI less of a replacement shell and more of Google’s preferred future runtime for individual Gemini coding users.
Teamwork and multi-agent direction: the CLI preview includes /teamwork-preview for coordinating dozens of subagents. Treat this as promising but immature: multi-agent speed is useful only when artifacts, permissions, and final diff review stay legible.

My practical take: Antigravity now belongs in two comparison sets. Against Cursor and Windsurf, it is an IDE with an agent manager. Against Claude Code, Codex, Gemini CLI, and opencode, it is Google’s new terminal/runtime path for Gemini-based coding agents.

Best For

Developers already comparing Gemini CLI, Google AI Pro, and Gemini-based coding workflows.
Product engineers building small apps where browser preview and implementation evidence matter.
Teams that want a more explicit supervision layer for agent work.
Evaluators who care about review artifacts as much as code generation speed.
Users who want to compare Google, OpenAI, Anthropic, and open-source agent stacks on the same task.

Not Best For

Teams that need stable enterprise procurement, mature support paths, and predictable quotas today.
Developers who primarily want terminal automation; Codex, Claude Code, Gemini CLI, opencode, or Aider may be cleaner.
Teams that need model portability across many providers.
Sensitive repositories where preview software, data handling, and command approval policies have not been reviewed.

Where It Beats Cursor

Antigravity is more interesting than Cursor when the job is no longer “edit this file” but “coordinate an agent, inspect its plan, see evidence, preview behavior, and decide whether the final patch is trustworthy.” If the Manager Surface and Artifacts reduce review time, that is a real advantage.

It also gives Google a native place to express Gemini model behavior in a full development environment. That matters if your team is already invested in Google AI accounts, Gemini CLI, or Gemini-based evaluation.

Where Cursor Still Wins

Cursor remains the safer default if you want a polished daily editor, mature onboarding, broad team adoption, and familiar IDE ergonomics. Antigravity needs to prove that the agent-first layer produces smaller, cleaner, more reviewable changes in real repositories.

Adoption Checklist

Verify current availability, account requirements, regional access, model access, and quota.
Test Fast mode and Planning mode on the same repository task.
Require every agent run to produce a reviewable plan, diff, and verification trail.
Keep terminal and browser permissions narrow until the team understands the tool.
Compare against Cursor, Claude Code, Codex, Gemini CLI, and one lower-cost option.
Record accepted diff size, review time, rollback clarity, and test results.

Quality Signal

The best signal is not a flashy app demo. The best signal is a patch that a teammate can review quickly: the plan matches the diff, the artifact explains the risk, the terminal commands are visible, and rollback is obvious.

The weakest signal is a beautiful agent transcript that leaves the final code hard to audit. Coding Agent Tools ranks Antigravity by review quality, not launch noise.

Gemini CLI for the predecessor terminal workflow and the enterprise/API-key path that still matters.
Claude Code for a mature terminal agent runtime with hooks, permissions, subagents, and long-running task patterns.
OpenAI Codex for ChatGPT-native cloud/local delegation, mobile steering, GitHub review, and Automations.
Cursor and Windsurf for editor-first daily coding alternatives.
opencode and Aider for open or Git-centered terminal workflows.
9Router and OpenRouter if model routing, fallback, and provider cost control are more important than Google-native access.
