Built For
Teams who need consistent APIs across languages and platforms
Game Development
Generate Unreal Engine plugins from API specs. Decouple game logic from backend services and iterate faster.
Automotive & Embedded
Create consistent C++/Qt interfaces across ECUs. Simulate hardware APIs before physical components exist.
Cross-Platform SDKs
Maintain one API definition, generate native code for every platform. Keep implementations in sync automatically.
Generate Production-Ready Code
From one YAML definition, generate complete SDKs with interfaces, stub implementations, unit tests, and build files. Zero manual boilerplate.
Develop Without Dependencies
Simulate APIs before backends exist. Test integrations without hardware. Let frontend and backend teams ship features in parallel.
Debug with Full Visibility
Monitor every API call in real-time. Trace property changes, method invocations, and signal emissions across your entire system.
How It Works
Define your API interfaces in YAML with properties, methods, and signals. Choose a template for your target platform. Generate complete, buildable code with one command. Iterate on your API — regenerate anytime without losing your implementation.
Native Code for Every Platform
Generate idiomatic code for C++14, C++17, Qt6, Unreal Engine, and Python. Each template produces code that follows platform conventions and best practices.
Stateful APIs That Match Your Code
ObjectAPI models interfaces with observable properties, callable operations, and server-pushed signals. Write in a developer-friendly IDL or YAML — both generate the same code. Designed for systems where state matters: automotive, gaming, IoT.
