About the Antigravity reference project
Quick Overview
This site is an independent reference project that documents Antigravity — Google's AI-native developer browser — drawing on public release notes, developer documentation, and technical community reporting. The team has no affiliation with Google, receives no editorial direction from Google, and holds no commercial relationship with the product.
Antigravity launched in late November 2025 and moved fast. Within weeks of release it had accumulated a release cadence that outpaced most dedicated documentation teams. The purpose of this reference project is to give developers a single, reliable hub for factual information about the browser: what it does, how to install it, how its security model works, what the API surface looks like, and how successive releases have changed the product. Nothing more ambitious than that.
Purpose and scope
The project covers the public-facing product surface of Antigravity. That means the desktop application, the agent runtime, the artifacts layer, the browser's extension and API surface, the login and identity model, and the security and sandbox architecture. It does not cover Google's internal engineering decisions, roadmap speculation, or product strategy beyond what has been publicly confirmed in official sources.
Scope is deliberately kept narrow. There are plenty of opinion pieces about whether AI-native browsers will reshape software development. This reference site is not that. Each page here is organized around a question a developer would ask when evaluating or using the tool: "How do I install it?", "What does the sandbox actually isolate?", "What changed in the last three releases?" When an answer is not yet settled in the public record, the site says so rather than speculating.
Editorial principles
Three principles guide every page on the site. First, accuracy over completeness: if a detail is uncertain, it is either omitted or flagged as uncertain. A gap in coverage is preferable to a confident error. Second, primary sources first: the editorial team prioritizes official release notes, the official Antigravity developer documentation, and direct product testing over secondary accounts. Third, freshness: pages are stamped with a last-reviewed date and reviewed whenever a new release ships.
The site uses plain, direct language. The audience is developers, not marketers. Sentences are short where short works. Jargon is included where jargon is the right word for the thing. AI-coding clichés — "leverage", "in today's digital landscape", "seamlessly" — are excluded on principle, because they add no information and reduce trust.
Independence disclosure
This site is independent. It has no affiliation with Google LLC. Antigravity and Google are trademarks of Google LLC; their use here is nominative and referential, not an assertion of any commercial relationship. The project receives no advertising revenue from Google, no sponsored content arrangements, and no early-access briefings in exchange for favorable coverage.
The site may contain affiliate links to hosting, tooling, or developer products unrelated to Antigravity. Any such links are labeled clearly. Revenue from those links funds hosting and editorial work. Those commercial relationships have no bearing on the accuracy or completeness of Antigravity coverage. For the policy framework on independent editorial standards, see the FTC guidance on editorial independence.
How pages are updated
The update workflow has three triggers. The first is a new Antigravity release: every time a version ships, the release notes page is updated within 24 hours and affected feature pages are queued for review within 72 hours. The second trigger is a material change in the official documentation — if Google updates the API reference or the security model documentation in a way that contradicts or extends what is written here, the relevant pages are revised. The third trigger is a corrections request from a reader.
Pages carry a "Last reviewed" signal in the coverage table below. This reflects the date the editorial team last audited the content against current product behavior, not just the date of publication. A page published two months ago and reviewed this week is more trustworthy than a page published yesterday without any verification pass.

About this site — the questions readers ask most
Four of the questions the editorial team receives most often about the project itself, answered directly.
-
Who runs this Antigravity reference site?
This site is run by a small independent editorial team focused on developer tooling documentation. The team is not affiliated with Google LLC and has no commercial relationship with the Antigravity product. Content is produced from publicly available sources: official release notes, the Antigravity developer documentation, direct product testing, and technical community reporting. Google and the Antigravity name are referenced here in a nominative, descriptive capacity. The editorial team profile is on the engineering team page.
-
Is this an official Google property?
No. This is an independent reference site. Google LLC publishes official Antigravity documentation through its own developer channels. This site is a separate, independent project that documents the product for the developer community. If you are looking for official Google support for Antigravity, the correct channel is the official product documentation and support portal rather than this reference site.
-
How often is the content updated?
Core reference pages are reviewed at minimum once per month. When the product releases a new version, affected pages are reviewed within 72 hours. The release notes page is updated within 24 hours of a public release. The "Last updated" column in the coverage table above reflects the most recent audit date for each area. If you notice outdated information, the contact page has the corrections process.
-
How can I flag an error on this site?
Use the contact form on the Contact page. Include the URL of the page containing the error, the specific sentence or passage you believe is wrong, and what the accurate information should be along with any supporting source. The editorial team reviews corrections within 48 to 72 hours and publishes corrections without a waiting period — if you are right, the page is fixed promptly. Significant corrections are noted with an inline correction notice on the affected page.
