Org-extensible and community-driven.","theCatch":"Vs Claude Code / Codex / OpenHands (coding agents): Spec Kit is the SDD workflow primitive — process and toolkit, not a coding agent seat. You still bring the agent, models, and repo discipline. GitHub org project, not a hosted product SLA.","verdict":"MIT SDD toolkit.
