Every few years a stack promises to make everything ten times better. For small systems, the promise is a distraction, the gains aren't in the framework, they're in the boring parts.
Clear data models, indexed queries, reliable deploys, readable code. These are the things that make a system fast to build and cheap to maintain, and they're stack-agnostic.
The 10x stack doesn't exist. The 10x discipline does: measure, simplify, and don't add a moving part until the numbers demand it.
