Kotlin + Ktor + Gradle API Starter
Ktor, Kotlin, Gradle, and JUnit 5 form a backend service configuration where the generated project is centered on a backend service. Better Fullstack can scaffold this exact compatibility-checked selection.
01 / selection
Stack at a glance
| Role | Technology | Repository description | Scope |
|---|---|---|---|
| Backend | Ktor | Coroutine-native Kotlin backend framework from JetBrains | Primary backend |
| Language | Kotlin | Idiomatic Kotlin sources for Spring Boot or Ktor | Project-wide |
| Database | None | Skip database integration | Project-wide |
| ORM | None | Skip Java ORM/database layer selection | Project-wide |
| Authentication | None | Skip Java authentication library selection | Project-wide |
| API | None | REST controllers only | Project-wide |
| Build tool | Gradle | Flexible Java build tool with Gradle Wrapper support | Scoped to the backend |
| Testing | JUnit 5 | Modern Java unit testing platform | Scoped to the backend |
02 / architecture
How the pieces fit
- The generated stack is centered on a backend service with no browser frontend.
- Gradle is scoped to the backend.
- JUnit 5 is scoped to the backend.

06 / checks
Compatibility notes
Compatibility checked against Better Fullstack types version 2.8.0.
The generated record has 0 graph issues and 0 disabled selected options. This is a compatibility check, not a claim that this exact scaffold received a runtime smoke verification.
- Database is intentionally set to none.
- Java ORM / Database is intentionally set to none.
- Java Auth is intentionally set to none.
- Java API Layer is intentionally set to none.

Questions
Is this combination supported?
It passes the repository's compatibility analysis, selected-option checks, stack graph validation, project schema parsing, and virtual generation. That result is described here as compatibility checked.
Does it generate one app or separate parts?
The generated project is centered on a backend service. The actual generated output uses a single-directory layout.
How can I customize the selection?
Open the generated builder link above. Its query parameters reproduce this selection, and the builder can change compatible options before generating a new command.
