API Model Forge

API Model Forge is a free MIT-licensed offline Windows developer utility by ALMARFELD. Load or paste JSON and generate C#, TypeScript, Kotlin, Python and Go models. v1.0.1 rejects duplicate keys/trailing malformed input and uses collision-safe identifiers and escaping. Copy or save generated files. Types are inferred from the sample, not a complete API contract: review them. Renamed Kotlin/Python JSON keys are recorded in comments; configure serializer mappings yourself. Go and C# preserve serialized names. Windows 10/11 x64 portable ZIP: extract fully and run APIModelForge.exe. Separate Microsoft Edge WebView2 Runtime required, not bundled or automatically installed. No accounts, uploads or telemetry. The executable is not Authenticode signed.
