# Hosted browsers and devices

> Official integrations with hosted browser and device services, one package per service.

An official integration is one package that gives a target its `browser` or
`device` from a hosted service, through the engine's provider interface.
Only the target's `browser` or `device` in the config changes.

## Use a service with no integration

For any other service, write a small provider in your project: a
[`BrowserProvider`](https://e2e.tester.army/docs/browser#hosted-browsers) for the web engine, or a
[`DeviceProvider`](https://e2e.tester.army/docs/mobile#hosted-devices) for the mobile engine.

To run e2e on a CI service such as GitHub Actions or Expo Workflows, see
[Continuous integration](https://e2e.tester.army/docs/ci).
