ETH: Ecosystem Developers
Ethereum Ecosystem Developers: daily data through 1 Nov 2026.
How many developers wrote code in the Ethereum ecosystem over the last 28 days, and how many of them work only there.
Why use it. Developers are the supply side of a network: where they choose to work is one of the longest-lead signals of where products and users will be. A rising count, above all of developers who work only here, points to lasting growth; a falling one, to a network losing its builders. How to read it. Exclusive plus multichain equals all developers. The series is a 28-day window, so it moves slowly: single-day changes do not mean much; compare quarters and years. Levels differ a great deal between ecosystems, so read each against its own past.
Calculation. Each day: the number of developers with at least one commit in repositories assigned to the Ethereum ecosystem, over the trailing 28 days, as published by Open Dev Data; exclusive developers committed only in this ecosystem in that window. Automated accounts are excluded by the source. Source: Open Dev Data by Electric Capital (opendevdata.org), used under CC BY 4.0: daily snapshots of developer activity in public repositories that its open taxonomy assigns to each ecosystem, on its own 28-day rolling method. The taxonomy is maintained by Electric Capital and contributors, so an ecosystem can gain or lose repositories over time, which moves the past as well. The chart ends about a week behind today, at the source's own pace; only public work on GitHub is seen.
