Gemini CLI was open source (Apache 2): https://github.com/google-gemini/gemini-cli

Antigravity CLI is not - the repo has a README and an animated gif demo: https://github.com/google-antigravity/antigravity-cli

As much as I like Gemini CLI and don’t like them shutting it down, I think it’s good some of the offerings are getting unified. There was too much fragmentation in the google offering and this is making it a tiny bit better.

I stopped using Google products due to their propensity for killing them off. I continue to be proven correct in my assertion that they do not care about their customers.

Google really can’t help themselves but to have some internal re-org kill off a public thing people are actively using. It’s honestly impressive how consistent they are.

Whoever is in charge of these decisions, is absolutely disconnected with the reality. First they sent a message saying the Ultra plan is ending, with no other option for a Workspace use to buy an equivalent plan. It was suppose to be active tilll June or July 7 , that's all. So the users are not suppose to know how they will need to plan or budget and just guess. I read once that after a certain level , the managers need to make their own decisions. Seems like someone just came in and decided that all the Gemini CLI and Antigravity needs to be one , because some other manager thought Antigravity was a better name than Gemini or whatever and started this mess in the first place. I am loosing my faith in these managers and Google.

Gemini CLI + Antigravity + Claude Code all working in the antigravity IDE together has been pure bliss. Gemini-CLI’s smart model fitting was absolutely incredible in the last month; on a simple pro plan with its built-in smart context hygiene I was able to maximize my token usage so much it felt broken. In hindsight, maybe it was!

Sad. I liked Gemini CLI. I used it a lot and occasionally use it these days. I've never tried Antigravity though.

I would love to sign up for antigravity cli but when I click on Get Plan it says: “This account isn't eligible for Google Antigravity benefits included with Google AI plans Google Antigravity benefits included with Google AI plans aren't available in some countries or for people under a certain age. Learn more about Google One feature eligibility.” With a button that says “Explore Google AI Plans” that when I click on it takes me to my Drive.

I can’t believe our Google account setup is different from any other startup in SF. Anyone have success with this? Do they even have a bot at Google that tracks this attrition?

Mechanics that I found in the binary with a few agents, more information than I could glean from the GitHub page or the docs:

- A Chrome DevTools Protocol / Playwright client.

- macOS Seatbelt sandbox (--sandbox flag) with some special Node / v8 stuff.

- Sentry for crash reporting and Unleash for feature flags.

- A SKILL.md system mirroring Anthropic's skills convention.

- Subagents, an artifacts review workflow (slash commands), and conversation rewind.

- Telemetry redaction in several places (good?)

- go-git bundled in there.

- go-enry / linguist's entire language table: many file extension/syntax tags (Cairo, Stacks Clarity, Modelica, KiCad, etc.) bundled in there.

All in all, a 140 MB Go binary with its own browser control stack, sandbox, Git, language detector, skills runtime, and subagent system.

I'm good, I'll stick with pi and codex. Less is more my friends.

I was working on a product that relies on ACP (agent client protocol). Gemini CLI supports ACP natively although it is missing some protocols. But I found that Antigravity CLI (agy) lacks ACP support! It's a bad sign for me.

Google foeling more like Hooli these days.

"need to install a complete desktop app to get access to our new CLI"

This is the right move but I don’t know if I am ready to try them again. I am still bitter from the significantly reduced quotas, even on Ultra, their highest tier. Claude became unusable for me.

It would be much better if they just gave up on Gemini for coding and exclusively adopted Claude models. Even Deep Mind folks themselves prefer Claude over Gemini[1].

Do people use antigravity? In my team, there is one guy but everyone else is on Claude code/GHCP

So it gains feature-parity with the Gemini vscode extension, which has stopped working the day they released it.

I read through the docs. There is no mention of whether programmatic usage or Agent Client Protocol will continue be supported in Antigravity CLI.

Stop working? It never even started working for me, I tried it and always just got errors or lack of quota.

Looks like Antigravity cli is moving to weekly limits whereas Gemini cli was daily. Ouch

So now there's 3 different Antigravity products: CLI, Antigravity 2, and Antigravity IDE. And Gemini CLI goes to the Google graveyard of products. Wow.

Welcome to the Google graveyard, Gemini CLI.

Not that it will be missed much. Using it was the worst experience out of any harness.

Yeah, so they are worried about things like CAS that let you use lots of CLI agents from different companies. The fork I'm using lets me use Claude and Codex, and Gemini if I want, but I haven't much lately. Anyway, that sounds like what's happening. Is that wrong?

And Antigravity CLI starts working from today, interesting

FWIW, centralising on a single harness in Antigravity seems like a great idea.

agy cli is a disaster and half baked product. It wont even resize itself when i maximize terminal.

This is so confusing. So what happens to Gemini Code Assist plans?

What do the Antigravity quotas mean per plan?

Crap! I was using this to manage my hledger files and it did a decent job.

Say goodbye to metered usage via API keys you control, and hello to opaque pricing and usage limits.

Good riddance. Gemini CLI was hot garbage.
