GILD verdict
Start teams without a Code Assist subscription on Antigravity, and keep Gemini CLI where its open source or GitHub Action matters.
Gemini CLI also stays while a contract runs. Move each team to Antigravity CLI on Gemini Enterprise seats before its final renewal, after running both on the same tasks.
Plan every team's move to Antigravity, where Google is investing, while Google still supports both coding agents. Gemini CLI is open source and serves existing Code Assist Standard or Enterprise subscribers and paid Gemini API or Vertex AI users. Google stopped selling new Code Assist subscriptions on October 9, 2026 and sends everyone else to Antigravity. Antigravity CLI took over Gemini CLI's free, Google AI Pro, and Ultra users on June 18, 2026, and Gemini Enterprise seats include it.
Choosing between Google Antigravity and Gemini CLI
Choose Google Antigravity if
- Your team has no Code Assist subscription, or yours reaches its final renewal before January 31, 2027 for annual plans or December 31, 2027 for monthly plans.
- Engineers want a desktop agent manager or editor extensions as well as a terminal agent.
- You want Claude models next to Gemini under a Google contract.
Choose Gemini CLI if
- You hold a Code Assist Standard or Enterprise subscription and want to keep its terminal agent until the contract ends.
- You need the agent's source open under Apache 2.0 or run it in CI through the run-gemini-cli GitHub Action.
- You bill Gemini through Vertex AI or a paid API key and want a terminal agent on that billing.
Side by side
| Dimension | Google Antigravity | Gemini CLI |
|---|---|---|
| Who can use it | Personal Google accounts in supported countries, free or on Google AI Pro and Ultra, and Gemini Enterprise Standard, Plus, and Pay-as-you-go users | Existing Code Assist Standard and Enterprise subscribers, and paid Gemini API key and Vertex AI users; free, Pro, and Ultra users moved to Antigravity CLI on June 18, 2026 |
| Surfaces | Antigravity 2.0 desktop app, the Antigravity CLI (agy), the original IDE, and extensions for VS Code, Visual Studio, JetBrains, Zed, and Xcode | Terminal CLI, headless scripts, the run-gemini-cli GitHub Action, and Cloud Shell |
| Team priceList prices in US dollars. Included usage differs by plan and is not directly comparable. | Included in Gemini Enterprise Standard or Plus seats, from US$30 per seat per month, with US$10 or US$15 of Antigravity credit per user per month | No new subscriptions since October 9, 2026; existing Code Assist Standard contracts US$22.80 per user per month on a monthly commitment or US$19 on a 12-month commitment |
| Usage limits | Seat credit pooled weekly per edition and location in Gemini Enterprise; five-hour and weekly quotas on Google AI plans | 1,500 (Standard) or 2,000 (Enterprise) model requests per user per day |
| Models | Gemini 3.8 Flash by default, Gemini 3.1 Pro, and Claude Opus 5.5 and Sonnet 5.5 on eligible plans | Google's Gemini models only |
| Open source | No published source code for the apps or the CLI | The CLI, under Apache 2.0 |
| Migration path | agy plugin import gemini converts extensions into plugins and commands into skills; GEMINI.md works unchanged, while skills paths and MCP settings move by hand | Supported to the end of the Code Assist contract; Google asks customers to plan the move to Gemini Enterprise before their final renewal |
What practitioners report, side by side
Each product's figures come from its own practitioners, for the group you pick.
Overall signal
All practitioners rate Gemini CLI −3, 13 points above Google Antigravity at −16. Most of the gap is in complaints, with 49 of Google Antigravity's 102 sources negative against 22 of Gemini CLI's 64.
The score counts the authors from all practitioners that take a side, one vote each with their latest view, and is how far positive votes lead negative ones, per 100 votes, so Google Antigravity's −16 rests on votes split 32 positive, 18 mixed and 48 negative and Gemini CLI's −3 on 20, 20 and 22.
A lead of a fifth of the votes reads positive and a lead of half strong positive, with the same lines below zero. The dots show each source, positive, mixed, negative. Use a task pilot to measure accepted work and review time.
Footprint on the Agentic Software Development stack
They differ on one of 12 layers. On CI/CD, Google Antigravity touches it and Gemini CLI supports it. Coverage is each product's placement on this stack, as its product page shows it. Core is a job the product owns; Supports and Touches are jobs it helps with. Coverage says nothing about how well a product does them.

| Headless Automation | Not a theme in its sources | 3 of 7 |
Each count is the sources that praise a theme, or raise it as a concern, out of those that discuss it. A row pairs the two products when both carry a theme under the same or an equivalent name.
A count ending in "so far" has under 5 sources from 3 authors among all practitioners. "Not a theme in its sources" means GILD found no theme of that name in that product's sources.
What practitioners raise as concerns
Gemini CLI's sources raise Needs Close Steering more often than Google Antigravity's. It is raised in 4 of the 6 Google Antigravity sources that discuss it, against 7 of 7 for Gemini CLI. Quotas & Plan Changes and Data Privacy reach 5 sources from 3 authors only for Google Antigravity, at 28 of 37 and 5 of 6. Gemini CLI needs a pilot on the same repository tasks before you choose on Quotas & Plan Changes and has 1 of 2 on Data Privacy so far. Quotas & Cost reaches 5 sources from 3 authors only for Gemini CLI, at 13 of 16. Google Antigravity needs a pilot on the same repository tasks before you choose on it.
