SST
SST (github.com/sst) is the developer-tools group behind the SST infrastructure framework and the
OpenCode AI coding agent. In this spoke it’s the maker of opentui, the Zig-core terminal-UI
framework — which OpenCode itself uses for its front-end, so SST both builds the UI toolkit and builds
on it. That self-consumption is a small vote for the agent-ready-ui thread: the same team ships an agent
and the UI layer shaped for it.
