The best stack for an MVP is rarely the newest one. It is the one your team can ship with quickly, hire for easily and operate without heroics.

Start from the business problem
List what must be true at launch: users, integrations, compliance and expected load. Most MVPs need far less infrastructure than founders assume.
Prefer boring, well-supported tools
Frameworks such as Laravel or a React and Node stack come with mature tooling, packages and a large talent pool, which lowers delivery risk.
Plan for change, not for scale you do not have yet
Keep the architecture modular, write tests around the core flows and measure real usage before optimising.
