Antigravity Setup Guide
Free
Explore a practice codebase before asking an agent to change it.
BEGINNER / GOOGLE DEVELOPMENT TOOL
1. Set the stage
Use the official desktop installer and a small Git project. Start with one workspace and inspect the agent's access settings.
1. Install the official app
Open antigravity.google/download, choose the correct operating system and processor, and run the installer. Launch the app.
2. Sign in & open a workspace
Complete the supported sign-in flow. Open a practice repository rather than a production checkout. Confirm the displayed working folder.
3. Review agent settings
Inspect terminal, browser, and file-action permissions. Choose a review-oriented starting configuration before granting wider access.
4. Run & inspect a first task
Ask it to explain the project without edits. Then request a small change on a branch, run the relevant check, and review the diff.
2. Lean working stack
| Stage | Role | | --- | --- | | Antigravity | Inspect & edit | | Git | Create checkpoints | | Local preview | Exercise the change | | Human review | Approve the diff |
Arrows in the visual sheet show the order of work. External connections require separate setup. Optional tools may be replaced with ones you already use. This is a suggested stack for this task, not a universal optimum.
State the finish line
Define the expected behavior and the test that demonstrates it. Ask for actual results rather than a statement that a listener exists.
Keep extensions minimal
Install only what the project needs. Add tool connections after the core workflow works and their access is understood.
3. First practice task
Inspect this practice repository without changing it. Confirm the folder and branch, explain its entry point, and propose one small UI improvement with a specific way to verify it.
Your setup is working when
The agent identifies the intended repository, the proposed change is bounded, and any later edit is visible in Git and tested in a preview.
Troubleshooting
Wrong folder? Reopen the workspace. Tool blocked? Review the stated permission. Failed check? Diagnose it rather than disabling it.
