Today we ship Aspire 13! Why 13? It’s a number that’s bigger than 10 but less than 14.
It marks the start of a new chapter for the project. We’re expanding beyond .NET, bringing the same, code-centric experience to Python, JavaScript, and more.

Some pretty amazing improvements coming in the next release of #aspire. And it's not all just about .NET, just deployed a Python-based app with a React frontend.
Total time time from `aspire new` to deployed in the cloud? About 10 mins including all the apps dependencies.

A redesigned UI for `aspire deploy` is shipping in Aspire 13! 🌟
Used Claude for UX brainstorming, Copilot for implementation, and got something that works great for both local dev and CI/CD.
