Aspire

Your stack, streamlined. 💫

Why developers love Aspire

Code-First Control

Define your stack in code—no YAML. Aspire launches locally, then shifts to real cloud services without changing your architecture. Dev and deploy, fully wired.

Modular and Extensible

Orchestrate your existing stack—frontends, APIs, containers, databases, and more — without rewriting or replatforming. Extend Aspire for anything.

Observability from the Start

Logs, traces, health checks—all local, all wired up automatically. OpenTelemetry included with zero setup.

Flexible Deployments

Ship it how you want — to Kubernetes, your own infra, or managed services. Aspire adapts to your environment, not the other way around.

Code-Centric Control

Describe your stack in code. Easily add services, connect them to each other, and get everything running locally with a single command.
