What it is and who it is for

In one sentence: Google’s agent development platform with a desktop workspace, terminal, editor integrations, and SDK.

Who it suits: Developers who want agents to work across code, terminals, and browsers with inspectable artifacts.

What you can do:

• Plan, edit, and run checks within a project.
• Manage workspaces and agent sessions.
• Verify interfaces with browser tools or integrate through an SDK.

Where to start: Choose the app, IDE, or an editor extension from official downloads; you do not need every surface. Sign in and open a test project.

Cost: The individual tier is $0/month with usage limits; higher allowances and organization options are available.

Access and setup: your first session

Choose the app, IDE, or an editor extension from official downloads; you do not need every surface. Sign in and open a test project.

Terminal users can install agy from the setup guide. The SDK is for programmatic integration.

A concrete task and how to check it

Start with a small page change that can be checked in the browser. Read the plan, then inspect files and behavior.

Example:

Add required-field validation while preserving styling. Verify empty and valid submissions and report actual checks.

Inspect plans, screenshots, and tests separately; a correct screenshot does not establish backend or authorization correctness.

Costs: software, models, and execution

The free individual tier has limits; Google AI Pro and other offers increase allowances or credit access. Check the selected model and surface. Pricing

Unlimited completion features do not imply unlimited agent execution. Observe actual allowance use on a small task.

Configuration and extensions

Configure model, project, and permissions for the chosen surface. The app manages sessions, IDE supports editing, CLI handles terminal work, and SDK enables integration.

Consult current authentication and platform requirements. Model availability can differ across app, standalone IDE, and editor extensions.

Permissions, data, and limitations

Agents can edit files, run commands, and operate a browser. Scope workspace, tools, and approvals, especially in signed-in browser sessions.

Versions and capabilities vary across surfaces, and models, networks, or dependencies can fail. Preserve a project baseline before multi-file work.

Frequently asked questions

Must I switch IDEs? No; supported extensions, app, and CLI are alternatives.

Does free mean unlimited models? No; check model access and allowances.

Is a rendered page enough? Verify interactions, data, and project checks too.
