Spark Stack is an AI-powered tool for building web applications via a chat interface, enabling rapid creation of MVPs and prototypes using natural language prompts. It targets developers and power users seeking to accelerate initial web development stages through AI-driven code generation and a real-time, collaborative environment.

How It Works

The core approach leverages AI models, supporting OpenAI and Anthropic, to translate natural language prompts into functional web application code. It features a real-time development environment with live previews and incorporates Chain-of-Thought reasoning for complex requests. The system supports multi-page app generation, integrates sketch/screenshot uploads for design input, and includes Git version control.
