Open-source Specification Workspace
"Spectacular is an open-source specification workspace for teams building software with humans and AI.
It keeps product intent, users, features, requirements, tasks, blockers and unknowns in one living source of truth, so stakeholders can clarify what is being built and coding agents can pull the right context before they touch the code.
Spectacular helps teams reduce ambiguity, cut rework and turn vague ideas into clearer, more implementable software."
