Google Antigravity IDE

Google Antigravity IDE is an agentic development environment for developers who want software work coordinated across coding, command-line operations, and browser tasks. It is best suited to individuals and small teams comfortable supervising AI agents and reviewing their output. The main trade-off is variable capacity: agent quotas and model access depend on the Google AI plan and workload.

Overview

Antigravity combines an AI-enabled editor with asynchronous local agents that can plan and execute tasks across workspaces and codebases. This makes it more capable than a suggestion-only editor for multistep work, such as changing code, running commands, checking a dashboard, and validating a user interface. Capacity is not a fixed entitlement, however, so heavy agent use can be less predictable than ordinary editing.

Key features

Its Agent and Tab tools provide helper suggestions and real-time code completion. Unlimited Tab completions on every plan provide a reliable baseline for routine typing even when agent quotas are constrained.

Agents can operate in parallel across projects. Git worktrees, scoped settings and permissions, and multiple folders support isolated work on several codebases without mixing project context. Their output can be delivered as Markdown plans, code-diff views, architecture diagrams, images, and browser recordings. Those artifacts give reviewers something concrete to inspect before accepting changes.

The browser agent can read dashboards, perform source-control actions, and test interfaces. That cross-surface reach is valuable for release and verification workflows, but it also makes permission controls important. On macOS and Linux, agents request approval before terminal commands outside the sandbox; on Windows, they request approval before any terminal command. Agents remain limited to project folders by default.

Database tools, an extensions marketplace, and official integrations for Visual Studio Code, Visual Studio 2026, JetBrains IDEs, Zed, and Xcode broaden where the workflow can fit. The standalone IDE runs on macOS 12 or later, 64-bit Windows 10, and Linux systems meeting its stated glibc and glibcxx minimums.

Pricing

The individual plan costs free. It includes a variety of agent models, unlimited Tab completions, unlimited Command requests, and basic weekly rate limits. It is the sensible starting point for solo developers evaluating agentic workflows, though the weekly limits and model availability can restrict sustained or demanding use.

Google AI Pro has custom pricing and adds more rate limits plus a flexible AI credit pool. Google AI Ultra also uses custom pricing, with even more rate limits, a flexible credit pool, and higher access to the latest Gemini models. Ultra is aimed at users whose workloads regularly exceed the individual allowance and who value broader model access.

The Business plan uses custom pricing billed through Google Cloud. It offers API access with consumption-based pricing, eligible Gemini Enterprise Standard or Plus plans starting at 30 USD per seat per month, and a pay-as-you-go option with a 0 USD seat fee plus consumption charges. That structure suits organizations budgeting cloud usage, but Antigravity IDE itself is not supported for enterprise customers; enterprise users are directed to Antigravity 2.0 or Antigravity CLI. BYOK and bring-your-own endpoints for extra rate limits or custom organizational contracts are not supported. All plans receive baseline Gemini access and unlimited Tab completions, while quotas vary with workload and may change.

Platforms

The standalone application supports macOS, Windows, and Linux, while the broader offering is listed for Android and API use as well. The published desktop requirements make compatibility worth checking before deployment, particularly on Linux.

Who it's for

Choose Antigravity if you want agents to handle connected editor, terminal, browser, and verification tasks, and you are willing to review plans, diffs, diagrams, and recordings. It is particularly appealing to solo developers and small teams coordinating parallel work across repositories. It is a weaker fit when you need predictable high-volume quotas, BYOK, or an enterprise-supported product.

Pros and cons

• Pros: Parallel local agents can work across multiple workspaces and codebases.
• Pros: Browser automation and structured artifacts extend assistance beyond code completion.
• Pros: Unlimited Tab completions and Command requests are included in the free individual plan.
• Pros: Project-scoped permissions and approval prompts provide meaningful command safeguards.
• Cons: Agent quotas and model availability depend on plan and workload, so capacity can fluctuate.
• Cons: Enterprise customers must use Antigravity 2.0 or Antigravity CLI instead.
• Cons: BYOK and custom organizational endpoints are unavailable.

Alternatives

Web Development IDEs is the broader category to browse when browser-focused development matters more than autonomous agents. For a more focused AI editing comparison, see AI Code Editors; for generation-first tools, use AI Code Generators.

Replit is a freemium, cross-platform option with a free Starter plan offering daily usage, one live project, and one background task at a time. GitHub Codespaces is preferable when cloud development environments and usage-billed compute are the priority, with listed 2-core and 4-core plans. Mendix targets visual application development, while Alpha Anywhere offers a free community edition for web and mobile apps connected to data sources.

Visual Studio Code, Theia IDE, and HBuilderX are free alternatives when a conventional editor is preferable. RubyMine is the more targeted choice for Ruby development.

Verdict

Google Antigravity IDE is a strong choice for individual developers who want parallel agents to execute and document multistep work across code, terminals, and browsers. Its free plan and unlimited Tab completions make experimentation easy. Look elsewhere if you need enterprise support, BYOK, or quotas that remain predictable under changing workloads.
