What is Aspire?

Discover why Aspire is the fastest way to build production-ready cloud applications — unified tooling that eliminates complexity.

Aspire explained

The AppHost

Define your entire app architecture in code — C#, TypeScript, and more. No YAML, no configuration drift — just code that describes services and dependencies.

See how it works

Understanding resources

Understand the resources, relationships, and wiring that make the AppHost the center of your distributed application model.

Learn resource modeling

Deployment & topology

Deploy anywhere with confidence. Your local dev setup automatically translates to Docker, Kubernetes, Azure, or any cloud provider.

Deploy all the things

Take the next step with Aspire.

Deploy the app you just built, or bring Aspire into an existing repo and model the stack you already run.
