# Reclient > Reclient integrates with an existing build system to enable remote execution and caching of build actions. Electron has a deployment of a [reclient](https://github.com/bazelbuild/reclient) compatible RBE Backend that is available to all Electron Maintainers. See the [Access](#access) section below for details on authentication. Non-maintainers will not have access to the cluster, but can sign in to receive a `Cache Only` token that gives access to the cache-only CAS backend. Using this should result in significantly faster build times . ## Enabling Reclient Currently the only supported way to use Reclient is to use our [Build Tools](https://github.com/electron/build-tools). Reclient configuration is automatically included when you set up `build-tools`. If you have an existing config, you can just set `"reclient": "remote_exec"` in your config file. ## Building with Reclient When you are using Reclient, you can run `autoninja` with a substantially higher `j` value than would normally be supported by your machine. Please do not set a value higher than **200**. The RBE system is monitored. Users found to be abusing it with unreasonable concurrency will be deactivated. ```bash autoninja -C out/Testing electron -j 200 ``` If you're using `build-tools`, appropriate `-j` values will automatically be used for you. ## Access For security and cost reasons, access to Electron's RBE backend is currently restricted to Electron Maintainers. If you want access, please head to `#access-requests` in Slack and ping `@infra-wg` to ask for it. Please be aware that being a maintainer does not _automatically_ grant access. Access is determined on a case-by-case basis. ## Support We do not provide support for usage of Reclient. Issues raised asking for help / having issues will _probably_ be closed without much reason. We do not have the capacity to handle that kind of support.
