Google Ends Gemini CLI for Free Users After 6,000 Community Contributions, Replacing Open Source Tool With Closed-Source Antigravity CLI
Google will shut down free access to the Apache 2.0-licensed Gemini CLI on June 18, replacing it with a closed-source Go rewrite that enterprise subscribers alone will inherit.
Overview
Google announced on May 19, 2026 that Gemini CLI — the open source AI coding terminal it released under the Apache 2.0 license in June 2025 — will stop serving requests for free and non-enterprise users on June 18, 2026. The tool attracted more than 6,000 merged pull requests from external contributors and accumulated over 100,000 GitHub stars before Google unveiled its replacement: Antigravity CLI, a closed-source Go rewrite with no publicly available source code, according to FOSS Force and The Register.
What Happened
Gemini CLI launched in June 2025 as a TypeScript-based AI terminal tool licensed under Apache 2.0. Over nearly a year, Google accepted more than 6,000 merged pull requests from outside contributors, and the repository accumulated over 100,000 GitHub stars, according to TechTimes.
On May 19, 2026, Dmitry Lyalin, Group Product Manager at Google, and Taylor Mullen, Principal Engineer, announced the transition. They stated that free users, Google AI Pro and Ultra subscribers, and individual Gemini Code Assist users would lose access on June 18. Enterprise customers holding paid Gemini Code Assist Standard or Enterprise licenses would retain Gemini CLI access and additionally receive Antigravity CLI, per TechTimes.
Lyalin and Mullen framed the consolidation as a product focus decision, writing: “We can serve you best by pouring our energy into a single product,” according to FOSS Force.
Antigravity CLI: Closed Source, Incomplete Parity
Antigravity CLI, unveiled at Google I/O 2026, is a Go rewrite and not a fork of Gemini CLI, according to ByteIota. Its GitHub repository contains only a changelog, readme, and GIF — no source code has been published, as noted by The Register. Google itself acknowledged that “there won’t be 1:1 feature parity right out of the gate,” according to The Register and Shopifreaks.
The tool also ships with a revised quota model: a compute-based quota that refreshes every five hours with a weekly ceiling, replacing the previous 1,000-request daily limit. Users have reportedly hit weekly limits at approximately 2,000 lines of generated code, according to ByteIota.
Launch partners including Figma, Shopify, and Stripe, which built integrations on top of Gemini CLI, were given a four-week migration window, according to ByteIota.
Community Backlash
The response on GitHub was swift and largely negative. The top reaction to the announcement was 31 thumbs-down, according to TechTimes.
Andrea Alberti, a contributor with 27 merged commits to the repository, asked in the discussion thread: “essentially working for free on a code base that will only be used in enterprises?” according to TechTimes.
One commenter summarized the community mood bluntly. Under the handle secretnarwhal, the message read: “So, basically, we’re making the project closed source. That’s it.” — a comment that circulated widely, appearing in coverage by TechTimes.
Another contributor, @lingyaochu, wrote: “That’s what you done, Google, open source Gemini CLI, get developers contribute to this, and then migrate the code to a close source project,” per TechTimes.
The website Killed by Google, which catalogs over 300 discontinued Google products, has added Gemini CLI to its list, according to TechTimes.
What We Don’t Know
Google has not disclosed whether it intends to open-source Antigravity CLI in the future or under what conditions enterprise access to Gemini CLI itself will continue to be maintained. The company has not responded publicly to the characterization of the transition as a bait-and-switch. It remains unclear whether third-party forks of Gemini CLI will emerge or remain viable given the tool’s dependence on Google’s model infrastructure.
Analysis
The Gemini CLI case fits a pattern that open source communities have documented repeatedly: a company releases a developer tool under a permissive license, attracts external contributions that improve the product, then restricts or discontinues access once a commercial successor is ready. The Apache 2.0 license that governed Gemini CLI permits exactly this — it grants anyone the right to use, modify, and redistribute the code, but places no obligation on Google to continue operating the service or making enterprise features available to the public.
What distinguishes this case is the volume of community investment absorbed before the pivot. More than 6,000 external pull requests is a substantial body of labor donated under the reasonable expectation of continued open access. Contributors who examined the GitHub history and discovered that Antigravity CLI is a separate Go codebase — not a continuation of their TypeScript work — found that their contributions did not carry forward into the replacement product.
The Linux Foundation’s Model Openness Tool, accessible at isitopen.ai and co-authored by Arnaud Le Hors of IBM alongside researchers from Oxford and Columbia, scores AI projects across 17 components and assigns openness ratings. Its existence reflects a broader push in the open source community to define openness more precisely at a time when the gap between an open license and an open ecosystem has become economically consequential, according to TechTimes.
