Common Use Cases

###💡 Why Surveys as Code?

Traditional survey tools lock your survey design into opaque GUIs and proprietary formats. Qlarr treats surveys as first-class code artifacts:

Version-controlled — store survey definitions in Git alongside your project
Reproducible — the same JSON + JS always produces the same survey experience
Composable — reuse logic, validation rules, and question blocks across surveys
Auditable — every branching rule and skip condition is explicit and reviewable
Portable — the same survey definition runs on web, Android, iOS, and Node.js
