Best for

✓ Best for

Developers building real-time video processing features in web applications
Teams needing to integrate Roboflow's hosted inference API into their JavaScript projects
Projects requiring lightweight and efficient model serving for interactive use cases

✓ Best for

Developers looking to integrate machine learning into web applications without server-side dependencies.
Teams that need real-time model inference directly in the browser.
Projects requiring WebGL-accelerated computation for performance-critical tasks.

Not ideal for

✕ Not for

Applications that require local model deployment without cloud dependencies
Scenarios where a heavier framework or platform is preferred over a library-based solution

✕ Not for

Applications needing high-performance training on large datasets, as this is better suited to GPU-powered servers.
Scenarios where offline functionality without internet access is required, since TensorFlow.js relies on the web browser environment.
