# Web Browser

Roboflow provides JavaScript packages for deploying computer vision models in web browsers.

### inference-sdk

Uses WebRTC to run inference on your video streams with the Roboflow Cloud and return live results with minimal latency.

* For live video streams
* When running Roboflow Workflows, or a model not supported on `inferencejs`
* On latency-sensitive use cases with **compute-heavy models**

### inferencejs

Uses Tensorflow\.js to run inference on your images and video streams on-device.

* For images and live video streams
* On latency-sensitive use cases with **light,** [**supported models**](https://github.com/roboflow/roboflow-product-docs/blob/main/deploy/sdks/web-browser/web-inference.js#supported-models)
* When internet access isn't continuously available (still required for initial load)
