What is Google Antigravity? Distinguishing the development platform from Gemini
Google Antigravity’s desktop, terminal, editor and programmatic forms, with the roles of its shared agent harness, Gemini models, artifacts and permissions.
Meet this tool
Google Antigravity is Google’s agentic development platform with desktop, terminal and editor workflows and programmatic integration. Gemini models interpret tasks and make decisions while its agent harness organizes tools and state. Antigravity is not a separate model, and its early editor interface no longer describes the entire product.
How an engineering goal produces reviewable artifacts
Antigravity calls structured task deliverables Artifacts, including implementation plans, code diffs and browser recordings. Plans describe intended work while recordings help inspect execution. They support review: a plan does not mean code was implemented. Match actual artifacts to the task goal.
Gemini is the model family; Antigravity is software for working with models. Switching interfaces or starting background tasks does not establish identical capabilities or permissions. Inspect model reasoning, repository files and execution tools separately rather than use a product name as a model identifier.
The desktop app and editor are different interfaces
Current interfaces extend beyond the original editor to a standalone app, CLI and SDK. Editors support direct code work, desktop workflows organize tasks and SDKs integrate with applications or automation. Check available interfaces and features for the version in use.
Workspaces define task context. Git worktrees isolate code edits but do not automatically isolate databases or external services. Parallel tasks need explicit write scopes instead of assuming multiple agents cannot conflict over shared state.
A shared harness connects models and tools
The shared harness connects Gemini, context, tools and events and supplies inspectable artifacts. Models propose actions, and software executes them and returns results. Visual reports and browser recordings aid review but must match real requirements; a polished plan is not completed implementation.
Check model and execution availability against configuration and account conditions instead of launch-era lists. Other coding products may use similar loops; compare actual tools and workflows.
Match permissions and validation to the actual environment
Permissions constrain directories and actions, while networks and services impose additional restrictions. Permission to build a page does not authorize unrelated account writes or production-data operations. Inspect actual approval policy rather than assume every interface shares defaults.
Open real artifacts, inspect changes and run checks in the target environment. Browser preview and healthy production release need separate verification. For mobile layout, test real text and viewports. Available validation tools do not establish that every device and boundary was automatically checked.
