Was there 2009-2014 and then again 2020-2026. I think there are a lot of aspects of IDE use and culture at Google that this post omits.

My recollection from 2009-2011 is that emacs and vim were the dominant editors (just as the TV show Silicon Valley depicted), and there was a decent-sized minority using Eclipse and Intellij, both of which had official support for Google tooling. The command line still largely ruled though, even though the official Google developer workstation was Goobuntu, Google-flavored Ubuntu. This reflected the overall developer population of the time.

I think Cider actually was invented a little earlier than the article describes. I have vague memories of some engineers experimenting with web-based IDEs that would integrated directly with Critique (the code-review software) as early as 2013-2014. Its use was not widespread when I left in 2014; there was still the impression that it wasn't powerful enough for daily driving.

When I came back in 2020, emacs/vim use was much lower, again probably reflecting differences in the general population of developers. Many more of the developers had been trained in the post-2010 developer ecosystem of VSCode, IntelliJ, etc, and this was reflected in tool usage at Google too. I'd say IntelliJ was the dominant IDE, with Cider a close second and Cider-V just starting to take market share. You still had to pry emacs and vim from a grizzled old veteran's hands.

By 2022 I'd transferred to an Android team, and Android Studio with Blaze was the dominant IDE, even as general IntelliJ usage in the company was falling. Cider just didn't have the same Android-specific support. Company-wide Cider-V was growing the fastest, taking market share from both IntelliJ and Cider-V.

By 2024 Cider-V was dominant and there started to be a concerted push to standardize on it, particularly since new AI agent tools were coming out and they couldn't be supported on all editors that Googlers wanted to use.

As of my departure in 2026, the company-wide push was to standardize on Antigravity [1], which, as I understand it, won a turf war within the developer tools org and got blessed as the "official" Google AI coding agent. This also has the effect of concentrating developer time dogfooding Google's external AI coding offering, which hopefully should improve its quality. There's still significant Cider-V usage, but it's dropping, and execs are pushing Antigravity hard.
