⚡ FullStackHero .NET 10 Starter Kit

A production-ready, modular .NET 10 monolith + two React 19 apps — the fastest way to ship a multi-tenant SaaS.

Identity, multitenancy, billing, auditing, webhooks, files, chat, real-time, caching, jobs, storage, OpenAPI and OpenTelemetry — already wired, fully tested, and 100% yours as source (no black-box packages).

Why FullStackHero?

Most starter kits give you a login page and a TODO list. This one gives you the boring, hard parts already done right — multitenancy, auth, billing, auditing, background jobs, real-time, file storage, observability — across a clean Vertical Slice backend and two polished React 19 front-ends, orchestrated locally with one command via .NET Aspire, and deployable to Docker or AWS.

You scaffold with the fsh CLI and get the complete, detached source — every BuildingBlock, Module, and Host project with real project references. No hidden NuGet runtime, nothing to "eject" later. Own it, read it, change it.

> Then open the Aspire dashboard at https://localhost:15888, the API + Scalar docs at https://localhost:7030/scalar, the admin app at http://localhost:5173, and the dashboard app at http://localhost:5174. Sign in with a seeded demo account (e.g. admin@acme.com / Password123!).
