Spec-Driven Development AI Coding Tools

Frameworks and toolkits that implement Spec-Driven Development (SDD) methodology, where specifications are written first and AI generates implementation from them. Does NOT include general code generation tools, AI coding assistants themselves, or tools that generate specs without structured SDD workflows.

There are 37 spec-driven development tools tracked. 1 score above 50 (established tier). The highest-rated is github/spec-kit at 69/100 with 78,175 stars. 1 of the top 10 are actively maintained.
