Bolt Diy

Bolt Diy is an open-source framework for building, running, and deploying full-stack web applications driven by large language models. It provides a structured environment where you can describe an application in natural language, have an LLM generate the code, then iteratively edit, run, and refine the project in a familiar web development workflow. Built by StackBlitz Labs, Bolt Diy is designed to work with any LLM provider, allowing you to plug in your preferred model or API.

The tool offers a project-based structure with clear file organization, support for common web frameworks, and an integrated development loop that includes code generation, execution, and debugging. You can run applications directly in the browser using StackBlitz’s WebContainers, test backend and frontend logic, and quickly apply changes suggested by the model or written manually. Typical use cases include scaffolding new full-stack apps, prototyping features, refactoring existing projects, and experimenting with multi-step agent workflows that modify and run code.
