OpenCode
SST / AnomalyTerminal coding agent from the Anomaly team, deliberately provider-agnostic across more than seventy model providers including hosted and local models. It offers a native terminal interface with multi-session parallel agents, shareable session links, automatic LSP loading, and a client/server architecture.
The repository was renamed from sst/opencode to anomalyco/opencode and the old URL redirects.

Adoption
4 medium confidenceOpenCode'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.
