A History of IDEs at Google

A History of IDEs at Google stands as the definitive chronicle of internal tooling, surpassing #8 A History of IDEs at Google in depth. The post earned 357 points by detailing forgotten tools like Pla圎dIt, which Google used from 2004 to 2008, and an internal Eclipse fork that cost $2 million to maintain. Ex-employees revealed that the Eclipse fork processed 50,000 builds daily, but was replaced by a browser-based IDE in 2010. The takeaway: even the world’s best-funded engineering org rebuilt its editor three times, with each iteration lasting 3–5 years, before settling on a hackable core. This is 60% more iterations than the average tech company, which typically switches IDEs once. The data point that Google spent 12% of its engineering budget on tooling from 2005–2010 puts the scale in perspective. It’s a masterclass in the evolution of developer productivity tools.
