Google Antigravity is an agent‑first IDE that lets AI agents plan, execute, and verify software tasks across an editor, terminal, and built‑in browser. It adds a Manager view to orchestrate multiple agents in parallel and uses Artifacts (plans, screenshots, recordings) so you can verify progress and give feedback while work continues.

Why Antigravity matters now

Traditional AI code tools focus on speed inside the editor. Antigravity shifts the centre of gravity: you describe the outcome, then agents plan, build, test in the browser, and report back with Artifacts you can audit. Two core surfaces—Editor and Manager—let you either stay hands‑on or coordinate multiple agents running in parallel.

In public preview, Antigravity is free for individuals, supports macOS, Windows, and Linux, and offers generous rate limits on Gemini models, with optional support for third‑party models. That mix makes it an attractive way to trial agent‑first development without changing your whole stack.

Key concepts and surfaces

• Editor view: A familiar IDE with tab completions, inline commands, and an agent sidebar for synchronous work.

• Manager view: A “mission control” for spawning and supervising multiple agents across workspaces—ideal for long‑running tasks, bug‑bashes, or parallel feature work.

• Artifacts: Instead of raw tool traces, agents publish task lists, implementation plans, screenshots, and browser recordings you can comment on. Feedback is incorporated mid‑run without resetting progress.

• Learning/memory: Agents can retain useful snippets and context to accelerate future tasks while respecting project boundaries.

Quick start (preview)

1. Download & install: Grab the latest preview build for your OS from the Antigravity site.

2. Sign in: Use a Google account; preview includes generous free usage for Gemini 3 Pro.

3. Open a repo: Load a local project or create a new workspace.

4. Run your first mission: In Manager, create a task (e.g., “Build a responsive landing page with tests”). Agents will plan, code, run the app in the browser, and publish Artifacts as they go.

5. Review & iterate: Comment on Artifacts to refine the work; switch to Editor for hands‑on tweaks or to run commands in the terminal.

Tip: For larger tasks, break the mission into milestones and enable parallel agents (e.g., API, UI, tests). Use Artifact checklists to track completion.

Model and tool support

• Gemini 3 (Pro/Flash) for core orchestration and coding inside Antigravity.

• Third‑party models: support for Anthropic Claude and GPT‑OSS variants (where enabled).

• Surfaces: integrated editor + terminal + browser so agents can run and verify code end‑to‑end.

Governance & UK alignment

Antigravity’s powers (file system access, terminal commands, browser control) demand sensible guardrails:

• Permissions: Run inside a non‑privileged workspace; constrain agent access to project folders.

• Backups & version control: Commit early and often; enable branch protections and CI checks.

• Auditability: Treat Artifacts as evidence; export and store them with change approvals.

• Data protection: Avoid sensitive data in prompts; apply retention policies for Artifact logs.

Practical use cases

• Feature sprints: Parallel agents build a slice (API, UI, tests), iterating via Artifacts until green checks.

• Regression reproduction: Delegate bug repro; the agent records the browser session and produces a minimal test case.

• Docs & demos: Agents generate step‑by‑step guides with screenshots and walkthroughs you can share.

Limits and good practice

• Rate limits: Preview includes generous quotas; expect refreshes on a timed cycle. Prioritise long‑running tasks in Manager to get more done per window.

• Human‑in‑the‑loop: Keep code reviews mandatory; comment on Artifacts at checkpoints.

• Safety: Disable destructive shell actions unless explicitly required; prefer sandboxed containers for risky commands.

Summary

Antigravity reframes the IDE around agent orchestration. With Manager vs Editor views, integrated browser/terminal, and verifiable Artifacts, it’s a strong entry point for teams piloting autonomous workflows—without abandoning existing tools.
