About

Technical decisions need the other half of the story.

WhenNotToUse exists because technical content disproportionately focuses on why tools are useful. Real engineering decisions require understanding trade-offs.

The question this site answers

The goal is to help developers ask the practical questions before a tool becomes part of an architecture:

• When is this tool the wrong choice?
• What assumptions need to be true for it to work well?
• What should I consider instead?

The site is intentionally focused on technology and software decisions. It does not try to be a general review site, a news site, or a place for ranking tools out of context.
