Access Google Antigravity
in Hong Kong without VPN
Although Hong Kong is not officially listed under supported regions, you can access Antigravity directly from HK without VPN via the Business Account Sign-In route linked to a Google Cloud Project!

Why It Failed Before & Why It Works Now
The secret is the sign-in entrance! Personal account sign-in checks regional whitelist. Switching to Business Account + Google Cloud Project bypasses this restriction.
1. Business Account does NOT require Google Workspace: Official Codelabs confirm standard personal @gmail.com accounts can use this route as long as they own a Google Cloud Project.
2. Billing Model: This route is Pay As You Go (billed by usage, offset by Cloud promotional credits), rather than monthly personal quotas. Currently, only Gemini models are accessible.
3. Google has not officially announced HK support; policies or interfaces may change over time.
What is Antigravity? How does it differ from Chat AI?
Traditional AI chatbots are conversational ("it talks, you do"). Google Antigravity is an autonomous AI Agent development platform: you hand over a complete task, and it plans, edits files, executes terminal commands, tests in a browser, and delivers verified Artifacts.
Assign Task
Define what you want in plain language
Autonomous Planning
Agent explores repository & breaks down steps
Cross-Tool Execution
Subagents work in editor, terminal & browser
Verification & Artifacts
Runs tests, captures screenshots & delivers reports
Step 1 | Assign a Task
Unlike chatbots where you talk back and forth, in Antigravity you assign an objective, and the agent takes over. (Tip: Click the 4 cards above to inspect each step!)
Four Surfaces, One Unified Agent Core (Pay Attention to Business Sign-In Support!)
Antigravity App (2.0+)
Standalone desktop application managing concurrent agents, scheduled automations, and browser actions. Featured in this tutorial!
Antigravity CLI (agy)
Terminal CLI (successor to Gemini CLI), ideal for command-line developers and remote environments.
Antigravity IDE
โ ๏ธ Official documentation explicitly notes: Business Sign-in supports App, CLI, and IDE extensions, but NOT the standalone Antigravity IDE!
Antigravity SDK
Python library allowing developers to build custom autonomous agents and workflows programmatically.
5-Step Account Setup, API Enablement & Sign-In Guide
Follow this checklist step-by-step. Checked steps are saved automatically in your browser's local storage.
Prepare a credit or debit card for identity verification ($0โ$1 temporary authorization). Unless you manually upgrade to a paid account, you will never be charged automatically when the trial ends!
Open console.cloud.google.com/freetrial directly โ Account shows Free trial account โ Billing > Credits immediately reflects $300 (approx. HK$2,353)!
Do NOT manually create a Billing Account in the Billing tab beforehand! Doing so creates a standard paid account without the $300 credits! (๐ก If mistakenly created: you can still click the Free Trial link to activate trial credits).
Create a new Google Cloud Project and verify it is linked to your Free Trial billing account. Remember: Antigravity sign-in requires your Project ID (e.g. my-project-123456), which may differ from the project name!
โ ๏ธ Crucial Verified Finding: If this API is not enabled, Antigravity will fail completely even after successful sign-in! Ensure your project is selected at the top, then click Enable:

How to Maximize $300 Free Trial + AI Pro/Ultra Monthly Credits
Usage on this route is Pay As You Go, but two major Google Cloud promotional credit sources can fully offset your bill! Use our calculator below:

Note: Check remaining credits under Billing > Credits (initial balance ~2,353.66). Billing reports update with slight delays.
๐ How to Claim AI Pro / Ultra Monthly Credits (3 Steps)
- Visit the Google Developer Program My Benefits page (sign in with your subscription's Gmail).
- Locate the monthly Google Cloud Credit card, click Select billing account, and choose your project's billing account (cannot be moved once applied).
- Click Apply! Each voucher card is valid for 1 full year from issuance.
โ ๏ธ Reminder: Once the $300 Free Trial expires (90 days), an upgraded billing account is required to continue using monthly credits. Always pair with Spend Caps.
Preventing Overcharges: Budget Alerts vs. Spend Cap
Because this route is Pay As You Go, any excess usage on an upgraded account will charge your card. Learn the critical difference between Budget (Alerts only) and Spend Cap (Auto-pause):
๐ง Budget (Alerts)
Sends email notifications at 50%, 80%, and 100%, but does NOT halt usage or stop billing.
๐ Spend Cap (Hard Ceiling)
Automatically pauses Agent Platform API calls when limit is hit, resetting automatically next month (or manually unpaused).
- Not Instantaneous: Latency between hitting cap and suspension means small overages during propagation are still billed.
- Evaluated on Pre-Credit "Gross Cost": E.g., a $40 cap pauses when gross spend hits $40, even if promotional credits would have covered it.
- Applies per Project & Service (Agent Platform) on a monthly cycle.

โ Frequently Asked Questions (FAQ)
Q1: Does "Use Business Account" require a corporate domain or Google Workspace?
No! Google Codelabs confirm that standard personal @gmail.com accounts can select "Use Business Account โ Continue with Google Cloud", provided they own a Google Cloud project with an active billing account.
Q2: Why do I see a "License not found" error during sign-in?
This occurs when you leave the billing option on the default "Gemini Enterprise" selection (which requires a pre-purchased enterprise seat license). You must select Pay As You Go instead. Once signed in, Settings > Account will display Gemini Enterprise Pay-as-you-go.
Q3: I already subscribe to AI Pro / Ultra in HK. Why do I get Starter Quota when signing in directly?
Personal subscription quotas in Antigravity are separate from Google Cloud Pay As You Go usage. Because HK is not on the personal consumer whitelist, consumer sign-in is gated. However, under this Business route, you can claim your monthly Pro/Ultra Google Cloud credits ($10โ$100/mo) via My Benefits and apply them to your cloud billing account.
Q4: Will I be automatically charged after the $300 Free Trial ends or reaches 90 days?
Official Google Cloud policy states that Free Trial accounts are never charged automatically unless you manually upgrade to a paid account. When the trial ends or credits are exhausted, services simply pause.
