Runtimes & Model Providers

Bolt.DIY Runtime

Uses WebContainers, a browser-based Node.js environment. This provides instant sandboxed execution but may not fully support native npm modules. For more details, visit WebContainers.

CodinIT.dev Runtime

Runs directly on your local Node.js environment. This ensures better performance and full compatibility with native modules. Learn more at Node.js.

Model Providers

Both platforms support popular providers like OpenAI and Hugging Face, with goals toward model-agnostic architectures. Consult each project’s README for configuration details and API key setup.

Choose CodinIT.dev if you prioritize:
  • Quick, low-friction setup for non-engineers
  • Superior local performance and native module compatibility
  • Simple documentation and onboarding
Choose Bolt.DIY if you need:
  • Extensive customization and broader provider options
  • Developer tools like diff viewers and advanced configurations
  • Safe, sandboxed experimentation in the browser
