What is bolt.diy?
bolt.diy is an open-source AI-powered app builder by StackBlitz. You describe what you want to build in natural language, and bolt.diy generates a full-stack web application: frontend, backend, database schema, and deployment configuration. It can run and preview the app in-browser using WebContainers, so you see results instantly without any local setup.
bolt.diy supports custom OpenAI-compatible providers. Add EUrouter in the provider settings, and every LLM call used to generate your application routes through EU infrastructure. This is relevant because bolt.diy sends detailed descriptions of your app requirements to the model, which may include business logic and proprietary specifications.
Quick to integrate
A few lines of code is all it takes. Swap your base URL and you are routed through EUrouter.

Follow these steps to connect your application to EUrouter.
Open bolt.diy
Go to bolt.diy or deploy your own instance from the GitHub repository.
Configure EUrouter as a provider
In the provider settings, select OpenAI Compatible and enter the EUrouter base URL and API key.
Build your app
Describe the app you want to build. bolt.diy generates the code through EU-routed models. All LLM calls stay within European infrastructure.
Why use bolt.diy with EUrouter
AI app generation through Europe
bolt.diy sends your app description and requirements to the model as context. That often includes business logic and proprietary specifications. With EUrouter, all of that routes through EU servers. Your app ideas stay in Europe.
- App descriptions and requirements route through EUrouter's EU servers
- Generated code and iterations stay within European jurisdiction
- Suitable for prototyping proprietary applications with AI
- No US data processing for your app specifications
Any model for generation
Through EUrouter, bolt.diy can use GPT-4o, Claude, Mistral, and more. Different models have different strengths for code generation. Switch models to find the best results for your project.
- Access all EUrouter models from the bolt.diy model selector
- Try different models for different types of applications
- One API key covers all model usage
- Switch models without changing provider settings
Open source and self-hostable
bolt.diy is fully open source. Self-host it on EU infrastructure, connect to EUrouter, and your entire app generation workflow stays in Europe. From prompt to preview, all within EU jurisdiction.
- Self-host bolt.diy on your own EU infrastructure
- All LLM calls route through EUrouter's EU servers
- Open-source codebase you can audit and customize
- In-browser preview via WebContainers, no data sent elsewhere
