Bolt.diy: The Ultimate Guide to AI-Powered Full-Stack Web Development
In the rapidly evolving landscape of web development, Bolt.diy (formerly oTToDev) emerges as a game-changing open-source platform that combines AI-powered coding with full-stack development capabilities. This browser-based tool lets developers harness multiple large language models (LLMs) to create, edit, and deploy web applications with unprecedented efficiency. Whether you're building a simple portfolio site or a complex web application, Bolt.diy offers a revolutionary approach that could transform your development workflow.
Why Bolt.diy Matters in 2024
The web development world has seen an explosion of AI tools, but most suffer from three critical limitations:
- Vendor lock-in to specific AI models
