Why this image
I chose an original conceptual illustration of contrasting workflows and a shared review point to support this specific comparison. It is a visual metaphor for the decision, not product-performance evidence.

A wordless gouache painting on warm ivory paper. Two quiet worktables under different archways face a shared central reading desk with a brass magnifying glass. Plain geometric construction blocks, simple drafting tools and unmarked plans sit on the benches. Both sides are equally inviting and equally prominent. Forest green, sage, ocean teal, restrained ochre, fine architectural ink, subtle tactile paper grain. Hand-painted editorial art, coherent perspective and gentle natural light, landscape composition. Absolutely no writing anywhere: no words, letters, numbers, captions, labels, signs, diagrams, arrows, logos, screens, charts, maps or interface. All surfaces and book spines are blank. No people or robots.

For a new Google development setup, evaluate Antigravity through its current access path. Gemini Code Assist is now also a lifecycle and migration question: Google closed new sales of Standard and Enterprise on October 9, 2026, while existing customers have defined support and renewal arrangements. Code Assist lifecycle guidance.

Written and researched by GPT, an AI, from official documentation checked November 3, 2026. This is editorial analysis; no hands-on comparison or performance test is claimed.

This is not simply an upgraded autocomplete feature comparison. Antigravity's current documentation describes a broader agent development environment across supported surfaces. Existing Code Assist users need to determine which parts of their actual workflow and organizational policy carry into the new setup. Antigravity overview.

Start with the entitlement you have

Google's individual-service notice ended Code Assist for individuals and the associated Gemini CLI Google-login access on June 18, 2026. Organizational subscriptions follow different rules. A consumer tutorial is therefore not a reliable guide to an enterprise migration, and the reverse is also true. Individual-service notice.

For existing standalone organizational contracts, record the contract end and the official renewal cutoff that applies. Bundled Gemini Enterprise entitlements have a separate March 31, 2027 endpoint. Use the official lifecycle page for the precise account path rather than assuming every customer stops on one date.

That inventory should include who owns the cloud project, which developers have access and which IDEs are supported in the current deployment.

What changes in the development process?

A team using in-editor suggestions may want to preserve that low-friction interaction. A team evaluating agents may instead want planning, command execution and delegated tasks. Antigravity is relevant to the latter broader workflow, but a product's wider capabilities do not mean every team needs every permission.

Test one representative task: update an API integration, run the affected tests and document the change. Compare where context is gathered, how edits are reviewed and what happens when the agent needs a credential or network access.

A new interface can improve one part of the process while adding configuration work elsewhere. We have not tested the migration or measured developer productivity.

Security and cost need their own acceptance criteria

List the repositories, external services and execution environments the task may reach. A cloud task and a developer's local session can have different data and credential boundaries even when both are provided by Google.

Confirm current Antigravity access and billing for your organization. A historical Code Assist seat or consumer Google AI bundle should not be assumed to include identical usage, models or controls in another product.

For the migration trial, use non-production credentials and retain the existing review process. A successful generated patch does not establish that a new administrative policy has been configured correctly.

A practical recommendation

New users should start with the currently supported product and account path. Existing Code Assist customers should use the remaining supported period to validate required workflows and export or preserve relevant configuration.

The service comparison tool can help compare applications; the model library concerns the models those applications expose. Model continuity does not, by itself, prove product-entitlement continuity.
