Stackologists staffs or builds three stacks. Pick from the repo already in production, not from a preference.
Home explains the studio. This chooser is for the moment you know you need a person or a build but have not named the stack yet.
.NET is the call when SQL Server, identity, and the service other teams call already live there. Blazor is the call when those same people should keep the screen in C#.
Angular is the call when the product is already a long-lived Angular app. Stackologists matches the version and the module map. A rewrite to React because hiring feels easier is not the offer.
React is a fit when the team already owns JavaScript and the public HTML has to be the product. It is not the first recommendation, and it is not a substitute for a system you already pay for.
