Google Antigravity CLI illustrates a concrete choice for software teams: whether the documented integration, authorization and release lifecycle are compatible with the work they want to delegate. This guide distinguishes supported facts from unknown account, region and permission details as of 25 October 2026.
Product and deployment surface
Google’s 2026 announcement presents Antigravity CLI as the successor destination for many consumer Gemini CLI workflows. It also states that the initial CLI would not have exact feature parity, while carrying forward important patterns such as skills, hooks, subagents and extensions in a changed plugin ecosystem. This is a product migration with possible workflow changes, not a silent model update.
Worked engineering scenario
Make an inventory before migration: installed Gemini CLI version, configuration directory, extensions, hooks, authentication method, custom scripts and repositories that rely on unattended CLI execution. Create a disposable project and test one read-only command, one controlled file edit and one scripted automation on the new client. Watch for changes in command exit behavior, file scope and approval UX.
Repository authority and data exposure
The announcement establishes a June 18, 2026 consumer-facing service change for certain Gemini CLI and Code Assist routes. It separately describes continued access for specified enterprise licenses and API-key users. Therefore, the statement “Gemini CLI was entirely shut down” would be inaccurate; entitlement and access route determine what changed.
Version, licensing and operational limitations
Shared agent harnesses can simplify development but also change what tools an agent may call. Inspect network access, extension provenance, generated hooks and data sharing under the new CLI before moving private repository automation. Deprecated hooks and renamed plugin formats should be documented as migration blockers rather than silently retried with elevated privileges.
When the product fits and when to wait
This guide is primarily for teams upgrading tooling in 2026 and deciding whether an existing script should remain on a supported enterprise path or move to Antigravity. No price, universal region support or one-to-one compatibility is asserted without plan-specific verification.
Alternatives and selection trade-offs
For a provider-neutral terminal baseline compare Claude Code, Codex CLI and Factory Droid. For the associated desktop workflow, examine the separate Google Antigravity IDE article.
A reproducible evaluation protocol
- Use a disposable, nonproduction repository at a recorded commit and remove real access tokens, private keys, client information and production data.
- Write acceptance criteria before engaging the assistant: at least one deterministic test, a static check and one failure or rollback scenario.
- Capture the actual tool version, model/provider route, authorized repository, permitted commands and network scope rather than relying on product branding.
- Inspect every changed file and generated dependency. Re-run the build, unit tests and security checks outside the assistant’s self-reported output.
- Separate evidence: vendor documentation, observed measurements from a future controlled trial, and editorial assumptions must have distinct labels.
What was verified—and what was not
The primary evidence for this article is vendor documentation or an original project repository available by the 25 October 2026 editorial cutoff. A product description is evidence of how its publisher represents a capability, not an independent security audit or benchmark. The exact installed build, account entitlement, country, processor, contract and provider model may change the result. We did not install or benchmark the tool for this article.
Availability, licensing and pricing boundary
Snapshot dated 25 October 2026. The verified material here does not provide a complete current price, seat allocation, model quota, region list, retention policy or binding commercial license for each possible tenant. Those entries are deliberately null or unresolved in the structured record. Consult an official account-specific agreement, and link any future numeric plan snapshot to the canonical AI10 pricing registry rather than reproducing a stale marketing offer.
