API Model Forge v1.0.1 - ALMARFELD

Generate C#, TypeScript, Kotlin, Python and Go models from JSON without uploading data. Load a JSON file or paste a response, choose a root type name, review language tabs and copy or save generated output. v1.0.1 rejects duplicate keys and malformed trailing data, handles name collisions and escaping, and clears stale output.

Installation

Windows 10/11 x64 portable ZIP. Microsoft Edge WebView2 Runtime is required separately; it is not bundled or automatically installed. No separate .NET runtime is required.

Extract the entire ZIP, keep packaged files/folders together, then run APIModelForge.exe. Obtain a missing WebView2 Runtime separately from https://developer.microsoft.com/microsoft-edge/webview2/. The app does not install or download it automatically.

Windows binaries are not Authenticode signed and Windows may show a reputation warning. Download only from official ALMARFELD/GitHub links or this verified mirror. Do not disable Windows security.

Features

• Validate JSON with line and column error locations
• Reject duplicate JSON keys and malformed trailing data
• Infer nested objects, arrays and optional or nullable fields
• Generate C#, TypeScript, Kotlin, Python and Go output
• Allocate collision-safe identifiers and escape unusual names
• Copy output or save generated files using a native dialog

Limitations and safety

Models are inferred from the sample, not a complete API schema or contract. Review generated types against the real service. Renamed Kotlin and Python JSON keys are recorded in comments; configure serializer mappings yourself. Go and C# preserve serialized names. This tool does not fetch API responses or validate runtime service behavior.
