We recently launched SpecForge, which generates app specifications. With majority (70% or more) of vibe coeded apps ending up in a tangled code mess and incomplete, we developed a process to generation specifications for our apps before development. This increased the app completion rate to 97% or more. SpecForge will take an idea and develop a specification or analyze an incomplete codebase on Github and reverse engineer to derive a specification.
