OpenCode's adoption is measured by npm downloads of opencode-ai, the package that is itself the installed product rather than a client of a separate service. npm is the declared channel but not the only one — an install script, Homebrew and prebuilt binaries are also offered — so this download count is a floor on total distribution, corroborated by a large GitHub star count on the same repository.
