💫 Toolkit to help you get started with Spec-Driven Development.
Build high-quality software faster.
An effort to allow organizations to focus on product scenarios rather than writing undifferentiated code with the help of Spec-Driven Development.
Spec-Driven Development flips the script on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: specifications become executable, directly generating working implementations rather than just guiding them.
