I built a .NET 10 starter kit because I was tired of starting from zero.
Every new project, same ritual.
Create the solution, then burn the first stretch on the stuff nobody sees: auth, multitenancy, logging, caching, file storage, background jobs, a real way to deploy.
By the time I reached the actual product, half the momentum was already gone.
So I stopped.
I took the setup I’d rebuilt a dozen times over, made it production-grade, and put it in one place.
It’s called FullStackHero, and it’s completely free.
It’s a modular monolith with a React frontend. .NET Aspire wires it together, EF Core 10 runs on PostgreSQL, logging and tracing are on from the first run, and there are 1,484 tests so it holds up well beyond “works on my machine.” Identity, multitenancy, billing, files, notifications are already in.
You install the template, create your solution and start on feature one.
Built to ship, not to demo. MIT licensed, no paid tier, no locked “pro” version keeping the good parts behind a wall.
If your next build is a .NET API or a SaaS, this saves you weeks. The repo is in the comments. If it helps you, a star genuinely keeps me going, and tell me what you’d change, because I keep improving it from what people actually hit in production.
I put all the details / guide into this article: <a href="https://codewithmukesh.com/blog/introducing-fullstackhero/" target="_blank" rel="noopener nofollow">https://codewithmukesh.com/blog/introducing-fullstackhero/</a>

FullStackHero is a free, MIT-licensed .NET 10 starter kit designed to eliminate repetitive boilerplate setup for SaaS and API projects. It ships as a modular monolith with a React frontend, wired together via .NET Aspire, using EF Core 10 on PostgreSQL. Out of the box it includes identity, multitenancy, billing, file storage, notifications, logging, tracing, background jobs, and 1,484 tests. The goal is to let developers skip weeks of infrastructure setup and start building product features immediately.
