Antigravity vs Claude Code (Oct 2026): Which Is Better?

Two of the most talked-about AI coding tools in March 2026 could not be more different in philosophy. Google Antigravity v1.20.5 is a full-featured IDE built on VS Code, bundling the Gemini 3.1 Pro model with a browser subagent, Mission Control, and AGENTS.md support. Claude Code v2.1.77 is Anthropic's terminal-native CLI, shipping the latest Claude Opus 4.6 with a 1 million token context window on Max, Team, and Enterprise plans.

One is built for developers who want to stay inside a visual environment; the other is built for those who live in the terminal. Both are excellent. Choosing between them is about workflow, not quality. In this guide I break down architecture, models, pricing, and every feature that matters in March 2026 so you can make an informed call.

Antigravity vs Claude Code: the short answer (October 2026)

• Pick Google Antigravity if you want a free starting point, a visual desktop App for running several agents, and Gemini 4 Argon or Gemini 3.8 Flash as the main model family.
• Pick Claude Code if you live in the terminal, want Claude models (Opus 5.5, Sonnet 5.5, Haiku 5.5) driving the agent, and are fine paying for a Claude plan (Pro is $17 a month on annual billing).
• Both now have a terminal CLI. Antigravity CLI (agy) and Claude Code (claude) are closer in shape than in March, so the real differences are the model vendor, the plan you already pay for, and whether you also want a desktop GUI app.
• You can use both on the same repo. Both support MCP and AGENTS.md.

Versions checked on October 30, 2026: Antigravity App v2.26.0 (October 22), Antigravity CLI v1.4.0 (October 16), Claude Code 2.1.312 (October 27, the latest release on its changelog). The March 2026 sections further down compared Antigravity v1.20.5 with Claude Code v2.1.77 and are kept as a dated archive; where they conflict with this section, trust this section.

Which is better, Antigravity or Claude Code?

It depends on the job and on which subscription you already hold. We do not have a verified, like-for-like test that runs both products on the same tasks, so we do not name a quality winner. The benchmark numbers quoted in the March 2026 archive below are vendor-reported and measure models, not the products around them. For the Gemini side, our Gemini 4 Argon guide separates vendor-reported from independent scores.

What you can compare today is cost, model access, surfaces and control. That is what the next sections cover.

Google Antigravity vs Claude Code: which models do they use? (October 2026)

Antigravity models by plan

Per Antigravity's “Choose a model” docs, availability depends on your plan:

The Claude 4.6 models and GPT-OSS-120b are marked “will be removed on November 2, 2026” in the docs. Older Gemini 3.x models still appear for Enterprise. You choose a thinking level (Low, Medium or High) per model. More on Argon in our Gemini 4 Argon guide.

Claude Code models

Claude Code's model docs list the aliases opus, sonnet and haiku. On the Anthropic API they resolve to Opus 5.5 (since v2.1.280), Sonnet 5.5 (since v2.1.284) and Haiku 5.5 (since v2.1.293). Resolution differs by provider, so the docs are the reference if you use Bedrock, Google Cloud or Foundry. Claude Fable 5.1 is the most capable option but is not the account default on any plan or provider; you select it with /model fable. On Pro, Fable draws on usage credits; on Max it uses part of your weekly limits. The docs say the default model follows your account type and can change, so check /model in your own session. Run claude update if a model request fails on an older install.

Antigravity vs Claude Code pricing (October 2026)

How limits work. Claude limits reset on a rolling five-hour session window with weekly limits on top, and Claude Code shares the same pool as chat. Antigravity shows Weekly and Five Hour limit remaining in its model picker. For how Antigravity credits behave, read Antigravity credits and pricing explained. For ways to try Claude Code without a subscription, see our free Claude Code guide.

Google AI plan prices come from the Google One AI plans page; Antigravity's own pricing page lists the $0 tier and describes higher tiers by rate limits. Prices exclude tax and can change. The March 2026 prices ($250 Ultra, $25 per 2,500 credits, $25 Team seats) in the archive below are historical.

Permission modes and auto-accept in Antigravity and Claude Code

• Antigravity presets: Request Review (every terminal command needs approval), Default (sandbox on; commands run in the sandbox without prompting and need approval outside it), Auto (Preview; also runs safe commands outside the sandbox, still prompts for sensitive or irreversible ones; not available for business or enterprise accounts) and Turbo (all commands run without prompting, no isolation). Since v2.23.0 (October 12, 2026) you can pick the preset from the message box.
• Claude Code modes: default (called Manual in the UI), acceptEdits, plan, auto (a classifier model reviews actions), dontAsk and bypassPermissions. Press Shift+Tab to cycle in the CLI. With Claude Code v2.1.283 or later, auto mode is the built-in starting mode for interactive terminal and VS Code sessions, unless your organization turns it off.

For step-by-step Antigravity settings, see our Antigravity auto-accept and autopilot guide.

MCP, skills and AGENTS.md support

• MCP: Antigravity config lives in ~/.gemini/config/mcp_config.json (global) and .agents/mcp_config.json (workspace), with an MCP Store in the IDE. Claude Code supports MCP too. This corrects the March claim below that Antigravity has no open protocol equivalent. Browse servers on our MCP hub.
• Instruction files: Antigravity reads GEMINI.md and AGENTS.md, with workspace rules in .agents/rules (12,000 characters per rules file). Claude Code reads CLAUDE.md, builds auto memory, and can read a repository's AGENTS.md in place of CLAUDE.md.
• Skills, workflows and plugins: Both support skills and plugins. Antigravity also has saved Workflows (12,000 characters per file). For Claude Code skills, see the Karpathy-inspired Claude Code skills guide.

Which should you choose? By use case

Can you use Antigravity and Claude Code together?

Yes. They run side by side on one repository because both read and write files and call Git. A practical setup:

1. Put shared project rules in AGENTS.md. Antigravity reads it, and Claude Code can read it in place of CLAUDE.md. For Claude-only guidance, add a short CLAUDE.md.
2. Configure the same MCP servers in both (Antigravity: .agents/mcp_config.json; Claude Code: its own MCP settings).
3. Work on separate branches or Git worktrees so two agents never edit the same files at once.
4. Use one tool to write and the other to review a diff. A second model family often catches different mistakes.

Antigravity's Free tier plus a Claude Pro plan costs $17 to $20 a month.

Antigravity vs Claude Code FAQ

March 2026 archive: the original comparison

The sections below are the original March 2026 comparison (Antigravity v1.20.5 vs Claude Code v2.1.77). Versions, models, prices and some feature claims have since changed; each section carries a note where it is outdated. Use the October 2026 sections above for current facts.

1. Quick Comparison Table (March 2026)

Historical (March 2026). Versions, models, prices and the MCP row are outdated; the current table is above under “side-by-side comparison table (October 2026)”.

2. Architecture: Full IDE vs. Terminal CLI

This is the most fundamental difference between the two tools, and it shapes everything else.

Antigravity: The Full IDE Experience

Antigravity is a fork of VS Code. When you install it, you get a complete development environment: a file explorer, integrated terminal, debugger, syntax highlighting, and extension marketplace. The AI layer is woven throughout — in the sidebar, in inline completions, and in the Mission Control panel (Cmd+E), which is a Kanban-style interface for spawning and monitoring background agents.

The result is a “manager” workflow. You open the IDE, describe a task, and an agent plans, codes, tests, and reports back while you work on something else. The tool comes with a built-in browser subagent powered by Gemini 2.5 Computer Use that can visually verify UI changes by screenshotting your running app.

Claude Code: The Terminal-Native CLI

Claude Code takes the opposite approach. It is a command-line interface installed via curl or npm and invoked directly from your terminal. There is no bundled graphical interface. You work inside your existing editor (VS Code, Neovim, Emacs, JetBrains, or anything else) and call Claude Code from a terminal pane when you need AI assistance.

Version 2.1.77 (released March 17, 2026) ships several CLI-first features that reinforce this philosophy:

• /voice — Dictate prompts via microphone directly in the terminal session, converted to text and sent to the model.
• /loop — Run a prompt repeatedly on a set of files or inputs, enabling batch automation without writing shell scripts.
• CLAUDE.md — Drop a CLAUDE.md file in your project root to give the agent persistent instructions, analogous to Antigravity's AGENTS.md.

Claude Code also integrates into VS Code and JetBrains as a plugin, so you can open an inline chat window without leaving your editor — but the underlying engine is always the CLI, and the terminal remains the primary surface.

Architecture Verdict

If you want a single unified environment with no context-switching, Antigravity wins on architecture. If you want maximum portability, composability with other CLI tools, and zero forced UI opinion, Claude Code wins. Neither is objectively superior; they represent different philosophies about where AI belongs in a developer's day.

3. AI Models: Gemini 3.1 Pro vs. Claude Opus 4.6

Both tools ship their respective vendors' most capable model as of March 2026. Here is how they compare on the benchmarks that matter most for coding work. Historical (March 2026): these models have since been succeeded by Gemini 4 Argon and Claude Opus 5.5, and the figures below are vendor-reported. See the October 2026 models section above.

Gemini 3.1 Pro (Antigravity v1.20.5)

Released by Google in February 2026, Gemini 3.1 Pro uses a Sparse Mixture-of-Experts (MoE) architecture. Its headline numbers:

• ARC-AGI-2: 77.1% — a dramatic leap from the 31.1% Gemini 3 Pro scored at the start of 2026, indicating a step-change in abstract and agentic reasoning.
• ScreenSpot-Pro: 72.7% — measures the model's ability to understand and interact with UI screenshots. Critical for the browser subagent.
• SWE-bench Verified: 76.2% — real-world bug fixing on open-source repositories.
• Context Window: 1 million tokens, loaded in full (no RAG chunking required).

Claude Opus 4.6 (Claude Code v2.1.77)

Anthropic's Claude Opus 4.6 is the default model for Claude Code v2.1.77, released March 17, 2026:

• SWE-bench Verified: 77.2% — a slight but meaningful edge over Gemini 3.1 Pro on standard software engineering tasks.
• ARC-AGI-2: ~40% — significantly behind Gemini 3.1 Pro on abstract reasoning.
• ScreenSpot-Pro: ~38% — limited vision/UI understanding.
• Output window: 64K tokens default, 128K tokens max output per request.
• Context Window: 1 million tokens available on Max, Team, and Enterprise plans.

Model Benchmark Summary

Key takeaway: Claude Opus 4.6 is marginally better at pure software engineering tasks. Gemini 3.1 Pro has a decisive edge in abstract reasoning and visual/UI understanding, which matters when running multi-step agentic workflows or fixing layout issues autonomously.

4. Pricing & Quotas (March 2026)

At the Pro tier, both tools cost the same. The differences emerge at higher tiers and in how each tool counts usage. For a deeper look at Antigravity's credit system, see our guide on Antigravity credits and pricing explained.

Historical (March 2026). Current prices are in the October 2026 pricing table above: Google AI plans run $4.99 to $199.99 a month, and Claude Pro is $17 a month on annual billing ($20 monthly). The Team seat price and the $200 Max figure below were March 2026 values.

Antigravity Pricing (March 2026)

• Free: Limited rate access to Gemini Flash models. Suitable for occasional use.
• Pro: $20/month (via Google AI Pro). Higher rate limits on Gemini 3.1 Pro. Individual developers who work intensively in the IDE will hit these limits during long agentic sessions.
• Ultra: $250/month (via Google AI Ultra, listed at $249.99). Consistent, high-volume access to Gemini 3.1 Pro and advanced models including Nano Banana Pro for image generation.
• AI Credits: Additional credits available at $25 per 2,500 credits for usage beyond subscription limits.
• Enterprise: Contact sales. Includes BAA, dedicated infrastructure, and organization-wide AGENTS.md policies.

One important caveat: agentic loops are token-intensive. A single Mission Control task running 20 minutes can consume thousands of internal reasoning tokens. Pro-tier users have reported multi-day quota lockouts after intensive agent sessions.

Claude Code Pricing (March 2026)

Claude Code is included in Anthropic's Claude subscription plans — it is not a separate paid product.

• Pro: $20/month. Includes Claude Code access with Claude Opus 4.6 at standard rate limits. Context window is 64K default / 128K max output.
• Max ($100/month): $100/month. Higher usage limits and access to the full 1M token context window.
• Max 5x ($200/month): $200/month. Five times the usage limits of standard Max, full 1M context, priority queuing.
• Team: $25/user/month (billed annually). Shared workspaces, admin controls, full 1M context for all members.
• Enterprise: Contact sales. Custom context, SSO, BAA, and dedicated capacity.

Pricing Comparison Table

Cost analysis: Claude Code is $50/month cheaper at the highest individual tier ($200 Max 5x vs $250 Antigravity Ultra). It also offers a $100/month mid-tier that Antigravity lacks — important for developers who need 1M context but cannot justify $250/month. Antigravity's free tier gives it an advantage for trial and low-volume use.

5. Features Head-to-Head

6. Developer Experience

Antigravity: Familiar GUI, Steep Agent Learning Curve

If you have used VS Code, Antigravity will feel immediately familiar. Extensions install the same way, keyboard shortcuts carry over, and the debugger works out of the box. The AI layer sits on top of this experience as an additional layer, not a replacement for it.

Where newcomers struggle is Mission Control. The Manager View introduces new concepts — Plans, Execution Status, Verification Results — that require a mental model shift. Teams that invest time in authoring a good AGENTS.md file see the biggest productivity gains; those who skip it find agents occasionally venturing outside intended boundaries.

A practical limitation: agentic tasks can silently exhaust quota on the Pro tier. Developers running long sessions sometimes find themselves rate-limited mid-task with no in-IDE warning until the task fails.

Claude Code: Low Setup, High Composability

Claude Code installs in under a minute. There is no IDE to configure and no extension marketplace to navigate. You drop a CLAUDE.md in your project and start delegating tasks via natural language in the terminal.

The /voice command (v2.1.77) removes the biggest friction point for developers who prefer speaking over typing long prompts. The /loop command enables repeatable automation — for example, running the same refactoring instruction across every file in a directory.

The downside is that Claude Code produces no visual feedback. You see text output in the terminal. For frontend work, you must visually verify changes yourself; there is no browser subagent to take a screenshot and confirm alignment.

Claude Code works best for developers who already have strong terminal habits and prefer composing tools (git, grep, make, docker) rather than having them all bundled in one application.

7. Extensibility: MCP Servers vs. VS Code Extensions

Claude Code: Model Context Protocol (MCP)

Claude Code's extensibility model is built on the Model Context Protocol (MCP). MCP servers are lightweight processes that expose tools — database queries, API calls, file system operations, browser control — to the Claude agent at runtime. You configure them in a .mcp.json file in your project or globally in ~/.claude/mcp.json.

MCP is language-agnostic and editor-agnostic. The same server that works in Claude Code also works in any other MCP-compatible client. This makes Claude Code a strong choice for teams that want to build internal tooling once and reuse it across the organization. Explore available integrations in our MCP Server Hub.

Antigravity: VS Code Extension Ecosystem

Antigravity inherits the full VS Code extension marketplace. Nearly every language server, linter, formatter, and debugger you currently use will install and run without modification. This is a significant practical advantage for teams that have already standardized their VS Code configuration.

Antigravity also supports a growing list of agent-specific integrations: Firebase, Google Cloud, Chrome DevTools, and various CI providers can be invoked directly from Mission Control tasks. In March 2026 these integrations looked Google-ecosystem-centric. Correction (October 30, 2026): Antigravity now supports MCP in the App, CLI and IDE (global config at ~/.gemini/config/mcp_config.json, workspace config at .agents/mcp_config.json), so the open, vendor-neutral protocol is available in both tools.

Extensibility Verdict

Antigravity wins for breadth — the VS Code marketplace has years of community-built tools. Claude Code + MCP wins for composability and portability, especially for teams building custom internal tools or working across multiple clients and editors.

8. When to Choose Antigravity

1. You are a frontend or full-stack developer: The browser subagent's visual verification (72.7% ScreenSpot-Pro) is genuinely useful when fixing CSS, aligning components, or iterating on UI layouts. No other tool on the market does this with Antigravity's accuracy.
2. You need extreme agentic reasoning: Gemini 3.1 Pro's 77.1% ARC-AGI-2 score is the best available in any coding product. For multi-step autonomous tasks requiring abstract reasoning, Antigravity has a decisive edge.
3. You prefer a unified IDE environment: If you want one application that handles editing, running, debugging, and AI delegation, Antigravity delivers that without context-switching.
4. You work on large or legacy codebases: The 1M token context window (available on all paid tiers) allows you to load an entire repository into active memory. No RAG chunking means no missed connections between distant files.
5. You are in the Google ecosystem: Firebase, Google Cloud, and Chrome integrations are native. GCP deployments and Firebase rules can be managed directly from Mission Control tasks.
6. You want to delegate tedious tasks completely: Library migrations, writing test suites, updating documentation, renaming patterns across a codebase — Mission Control handles these asynchronously while you continue coding.
7. You need built-in image generation: Nano Banana (Gemini 2.5 Flash Image) and Nano Banana Pro (Gemini 3.1 Pro Image) produce license-free placeholder assets at 1K–4K resolution, directly inside the IDE.

For a broader comparison of tools in this category, see our Cursor vs Antigravity guide.

9. When to Choose Claude Code

1. You live in the terminal: If your workflow already revolves around shell commands, git, make, and CLI tools, Claude Code integrates without changing any of that. It is just another command you pipe and compose.
2. You want editor freedom: Claude Code works equally well alongside Neovim, Emacs, VS Code, JetBrains, or any other editor. You are not locked into a VS Code fork.
3. You need voice input: The /voice command in v2.1.77 is the cleanest implementation of voice-to-code currently available in any CLI tool.
4. You need the best SWE-bench score: Claude Opus 4.6's 77.2% on SWE-bench Verified gives it a marginal edge for standard software engineering tasks: bug fixes, refactors, and feature implementation in established codebases.
5. You want lower high-volume costs: At $200/month for Max 5x (vs $250/month for Antigravity Ultra), Claude Code is $50/month cheaper at the top individual tier. The $100/month Max plan provides 1M context with no Antigravity equivalent.
6. You want MCP extensibility: If your team is building internal tools or integrating with proprietary systems, MCP's open protocol makes those tools reusable across any MCP-compatible client — not just Claude Code.
7. You care about data privacy: Claude Pro and higher plans do not use your conversations to train models by default, with no toggle required. Antigravity's telemetry is enabled by default and requires manual opt-out.
8. You want batch automation with /loop: The /loop command enables scriptable, repeatable AI operations on sets of files — useful for enforcing style rules, translating strings, or applying transformations across a large project.

10. The Verdict: Which One in March 2026?

The Short Answer

Choose Antigravity if you do frontend work, prefer a full IDE, or need the most capable agentic reasoning model available. Choose Claude Code if you prefer the terminal, want editor flexibility, need voice input, or want the best SWE-bench score at a lower price ceiling.

The Nuanced Answer

These two tools are complementary more often than they are competitive. Many developers on our team use Claude Code as their day-to-day coding companion — it sits in a terminal pane, handles specific tasks on demand, and stays out of the way otherwise. When there is a complex frontend issue that requires visual inspection, or a large background task that should run while they focus on something else, they open Antigravity and delegate to Mission Control.

The clearest single-tool recommendation is this: if you are new to AI coding tools and want to start somewhere, Antigravity's free tier is the lowest-friction entry point. If you already have a terminal-centric workflow and want the most powerful model for code-specific tasks without changing your toolchain, Claude Code Pro at $20/month is an exceptional value.

The Agentic Era in March 2026 is not about choosing one IDE. It is about understanding which tool matches the task at hand.

Historical note, March 2026 — This verdict reflects data from Antigravity v1.20.5 release notes, Claude Code v2.1.77 changelog (March 17, 2026), Gemini 3.1 Pro benchmark disclosures, and pricing from Anthropic and Google AI subscription pages as of March 2026.
