Google Antigravity
// November 18, 2025
Antigravity is Google's new "agent-first" IDE that ships with Gemini 3 Pro at its core while staying compatible with other models such as Claude Sonnet 4.5 and GPT-OSS. It keeps the familiar VS Code experience but layers in agents that can plan entire builds, fan out tasks across terminals, editors, and browsers, and then prove what happened with recorded evidence. The Verge captured Google's positioning well.
Why it matters
- Artifacts for accountability. Every session generates plans, screenshots, terminal logs, and browser recordings that act like tamper-proof changelogs so you can verify agent output quickly.
- Dual operating modes. The Editor view feels like a standard IDE with an embedded agent, while Manager view is a "mission control" for orchestrating multiple agents running in parallel workspaces.
- Native browser control. Agents can open Chromium views, click through flows, and attach the recordings to their reports, making end-to-end feature testing a default.
How I use it already
- Spec + ship loops. I drop a mission brief into Manager view, spin up two agents (one for backend, one for UI), and let them coordinate through shared Artifacts while I review their checkpoints.
- Autonomous regression hunts. The browser-enabled agents rerun critical flows overnight and attach GIF-like recordings when something breaks.
- Model bake-offs. Because Antigravity supports non-Google models, I can quickly see when Gemini 3 Pro, Claude Sonnet 4.5, or GPT-OSS is the better fit for a particular task.
Access notes
- Public preview today on Windows, macOS, and Linux with generous free rate limits that refresh every five hours.
- Workspace accounts are still rolling out, so I'm using a standalone Google account that consents to share logs with Google for now.
- Expect rough edges: terminal tool calls can fail and the preview sometimes declares a task done while leaving browser errors in the Artifact feed. Keeping Replit or local envs nearby helps when the agents need a manual rescue.
