How to Set Up Google Antigravity IDE Safely (2026)

Reviewed August 15, 2026. Google Antigravity is an agentic development platform, not a single fixed 2025-era editor release. The current official codelab describes a standalone application, Antigravity IDE, Antigravity CLI, and an SDK. This setup guide removes stale version, subscription, model-menu, and Windows-only WSL requirements that cannot safely be generalized.

Install only from Google’s official Antigravity download path. Begin with a personal or organization-approved Google identity, a non-sensitive repository, and review-driven permissions. Availability, supported operating systems, and enterprise controls must be confirmed on the download and account surfaces at installation time.

Prepare the endpoint and pilot

Google's codelab currently lists local installation for macOS, Windows, and specific Linux distributions and uses Chrome plus a Google account in its walkthrough. Treat the current installer as authoritative; do not force WSL or copy unofficial package commands unless the selected workflow actually requires them.

• Confirm the operating system and architecture are listed on the current official download page.
• Patch the operating system, browser, Git client, runtime tools, and endpoint security software.
• Create a test repository with no production secrets, customer data, signing keys, or live infrastructure credentials.
• Record the installer source, version, identity, selected policies, plugins, and models for later review.
• Define which file, terminal, browser, network, and external-tool actions require approval.

Install from the official source

Do not install an unofficial “Antigravity” package from a marketplace or shell snippet. Keep the downloaded installer and its provenance in endpoint-management records when deploying to a business fleet.

1. Navigate directly to the official Antigravity download page and select the supported package.
2. Verify the publisher signature or platform trust prompt before execution.
3. Complete the sign-in flow with the approved Google account.
4. Select review-driven development during the initial policy setup.
5. Install only the command-line launcher and extensions required for the pilot.

Configure least privilege

Review advanced security settings before opening a real repository. If a feature needs broad access, document the business need and compensating controls instead of silently relaxing the policy.

Validate the first task

Capture failures as well as successes. An acceptable pilot demonstrates predictable approvals, reviewable diffs, repeatable tests, and recovery—not merely code generation.

1. Ask the agent to explain the repository and propose a plan without writing.
2. Approve one bounded change and inspect every command and file diff.
3. Run the repository tests and security checks outside the model response.
4. Confirm the agent did not access unrelated files, accounts, or network destinations.
5. Revert the test branch and verify the rollback procedure before expanding access.

Implementation and review gate

Re-run the installation on each supported operating system before publishing step-by-step screenshots or commands. Version numbers, model choices, plan limits, and installer behavior must come from current Google sources.

ITECS can help Dallas organizations plan and validate this work through cybersecurity services. Product, legal, security, and compliance decisions remain subject to the organization’s current requirements and the named review gate below.
