• Continuous Code Generation: Seamlessly update files when your specs or logic change.
• Spec-Driven: Keep everything aligned with your vision using structured, spec-based guidance.
• Versatile: Generate UI components, APIs, configuration files, and even entire mobile applications.
• Framework Agnostic: Build for React, Vue, Angular, or just Vanilla JS.

SpecUI processes your specs using a series of Generators, Templates, and Processors to output clean, production-ready code. It's a spec-first approach that empowers you to ship faster than ever.
