A Reddit user says they booted a hand-assembled build of Googlebook OS on an ASUS Chromebook Plus and that it felt as fast as ChromeOS or faster, Chrome Unboxed reports. The build is unofficial. Google says only that many newer commercial Chromebooks can upgrade, and the Google pages checked list no models.
What the poster reports
Chrome Unboxed says user u/mawitime posted photos and impressions to the r/Googlebook subreddit on Reddit. It describes the build as a "Frankensteined" version of Googlebook OS booted on an existing ASUS Chromebook Plus.
According to Chrome Unboxed, the laptop has an Intel Core i5-1235U, 16GB of LPDDR5 memory and 256GB of UFS 3.1 storage. It quotes the poster: "This is not going to slow down existing machines at all – in some cases it feels even faster than ChromeOS."
Chrome Unboxed says the poster added in the comments that they expect 8GB models to run fine too. It also reports that the poster spent several days building the image with Google Antigravity, and that the build likely drew on an official ASUS Googlebook recovery image.
What does not work
Chrome Unboxed reports that Wi-Fi, audio and Pixel cross-device features were broken in the build. It adds that developers are tinkering with a repository called gbrunch, which aims to bring Googlebook OS to unofficial x86 hardware.
Chrome Unboxed says it does not recommend wiping a daily-driver Chromebook to install a driver-less build. This is one person's impressions, not a benchmark, and the build is unofficial. For another unofficial install, see our report on Googlebook OS in a Mac virtual machine.
What Google has said about existing Chromebooks
Google's support page, last updated Sept. 23, 2026 and written for IT administrators, says: "Many newer commercial Chromebook models will be capable of upgrading to Googlebook OS. Details on migration paths and device eligibility will be shared at a later date."
Google's page also says ChromeOS devices will keep receiving updates and security patches through mid-2034. It says that for qualifying devices purchased today whose 10-year support lifecycle extends beyond 2034, Google is committed to supporting the move to Googlebook OS, with many offering direct migration paths.
Google's Auto Update policy page says ChromeOS devices receive 10 years of updates from the platform release date, so each Chromebook has its own end date. Google's support page says current Chromebooks keep getting updates through their supported lifetime.
As of Oct. 15, 2026, the Google pages checked (support page, launch post and Googlebook site) did not list eligible models, hardware requirements or an upgrade start date. Google's wording covers "newer commercial" models and does not say whether consumer Chromebook Plus laptops are included.
Why it matters
Our assessment: the boot report suggests a 12th-gen Intel chip can run the new OS smoothly, but a build without Wi-Fi or audio is a proof of concept, not an upgrade.
If you own a Chromebook, Google's wording points to newer commercial models first, and the pages checked list no eligibility details to wait on yet. Your current laptop keeps its ChromeOS updates until its own end date. For what Googlebook is like today, see our launch problems report.
What is not confirmed
Google has not said which Chromebook models it will upgrade, or when, and has not said whether consumer Chromebook Plus models are eligible. The poster's claims about speed and 8GB support reach us only through Chrome Unboxed and are untested.
