Developing Browsertrix Cloud

Browsertrix Cloud consists of a Python-based backend and TypeScript-based frontend.

To develop Browsertrix Cloud, the system must first be deployed locally in a Kubernetes cluster.

The deployment can then be further customized for local development.


The backend is an API-only system, using the FastAPI framework. The latest API reference is available under ./api of a running cluster.

At this time, the backend must be deployed in the Kubernetes cluster.


The frontend UI is implemented in TypeScript, using the Lit framework and Shoelace component library.

The static build of the frontend is bundled with nginx, but the frontend can be deployed locally in dev mode against an existing backend.

See Running Frontend for more details.
