What this developer tool does
The generator validates identifiers, parses field definitions, and produces Kotlin source plus dependency guidance for Android and server-side templates.
Parse name and field definitions → validate Kotlin identifiers → select template → add nullability, defaults, annotations, and imports → generate code.
Generated architecture templates require project-specific package names, dependencies, lifecycle decisions, and error handling before production use.
Example
The page loads a working Kotlin Generator example. Run the tool to compare the sample input with the generated output and status summary.
Tips for better output
- Start with valid, isolated code or data.
- Review heuristic and inferred results manually.
- Use the official compiler, formatter, linter, or IDE before production use.
FAQ
How do I generate a Kotlin data class online?
Choose Data Class, enter the type name, provide fields in name: Type format, and generate the source.
Can I generate Android ViewModel or Retrofit templates?
Yes. The generator includes lightweight ViewModel and Retrofit interface skeletons for customization.
How do I specify nullable Kotlin fields?
Add a question mark to the type, such as String?, in the field definition.
Can this browser tool replace the official compiler or IDE inspection?
No. It performs browser-based formatting, conversion, structural parsing, or heuristic analysis. Always verify production code with the official toolchain.
Does this tool upload my source code?
No processing is implemented by the page itself in your browser. Review your hosting and analytics configuration separately if you add external services.
