Spektrum is a vibe coding SDK that converts natural language prompts into fully deployed web applications. Using a simple JavaScript SDK, developers describe what they want to build, and Spektrum handles code generation, environment setup, and deployment automatically, returning a live URL. The tool supports both a programmatic SDK approach and a visual platform UI. A demo prompt of 'Create a gamified app for learning Japanese vocabulary' produced a complete dashboard with progress tracking, flashcards, and a leaderboard in under a minute. Pricing is token-based at roughly $0.50 per app generation.
