# Remote Caching

Turborepo's [task cache](/docs/crafting-your-repository/caching) saves time by never doing the same work twice.

But there's a problem: **the cache is local to your machine**. When you're working with a Continuous Integration system, this can result in a lot of duplicated work:

<ThemeAwareImage
  dark={{
  alt: "Local caching creates a cache on each system.",
  src: LocalCachingDarkImage,
  props: {
    width: 896,
    height: 345,
  },
}}
  light={{
  alt: "Local caching creates a cache on each system.",
  src: LocalCachingLightImage,
  props: {
    width: 896,
    height: 345,
  },
}}
/>

Since Turborepo only caches to the local filesystem by default, the same task (`turbo run build`) must be **re-executed on each machine** (by you, by your teammates, by your CI, by your PaaS, etc.) even when all of the task inputs are identical — which **wastes time and resources**.

<Callout type="info">
  You don't have to use Remote Caching to use Turborepo. While Remote Caching
  will bring the most significant speedups, you can make your existing workflows
  faster without Remote Caching, too.
</Callout>

A single, shared cache [#a-single-shared-cache]

What if you could share a single Turborepo cache across your entire team (and even your CI)?

<ThemeAwareImage
  dark={{
  alt: "Remote caching creates a shared cache for your entire team.",
  src: RemoteCachingDarkImage,
  props: {
    width: 896,
    height: 489,
  },
}}
  light={{
  alt: "Remote caching creates a shared cache for your entire team.",
  src: RemoteCachingLightImage,
  props: {
    width: 896,
    height: 489,
  },
}}
/>

Turborepo can securely communicate with a remote cache - a cloud server that stores the results of your tasks. This can save enormous amounts of time by **preventing duplicated work across your entire organization**.

Remote Caching is free and can be used with both [managed providers](https://turborepo.dev/docs/core-concepts/remote-caching#managed-remote-cache-with-vercel) or as a [self-hosted cache](https://turborepo.dev/docs/core-concepts/remote-caching#self-hosting).

<Callout type="info">
  Remote Caching is a powerful feature of Turborepo, but, with great power,
  comes great responsibility. Make sure you are caching correctly first and
  double check [handling of environment
  variables](/docs/crafting-your-repository/using-environment-variables). Please
  also remember Turborepo treats logs as artifacts, so be aware of what you are
  printing to the console.
</Callout>

Vercel [#vercel]

[Vercel Remote Cache](https://vercel.com/docs/monorepos/remote-caching) is free to use on all plans, even if you do not host your applications on Vercel. Follow the steps below to enable Remote Caching for your repository.

For Local Development [#for-local-development]

To link your local Turborepo to your Remote Cache, authenticate the Turborepo CLI with your Vercel account:

```bash title="Terminal"
turbo login
```

You can also use your package manager if you do not have [global `turbo`](/docs/getting-started/installation#global-installation) installed:

<PackageManagerTabs>
  <Tab value="pnpm">
    ```bash title="Terminal"
    pnpm dlx turbo login
    ```
  </Tab>

  <Tab value="yarn">
    ```bash title="Terminal"
    yarn dlx turbo login
    ```
  </Tab>

  <Tab value="npm">
    ```bash title="Terminal"
    npx turbo login
    ```
  </Tab>

  <Tab value="bun">
    ```bash title="Terminal"
    bunx turbo login
    ```
  </Tab>
</PackageManagerTabs>

<Callout type="info">
  If your Remote Cache is configured to use single-sign-on you will need to run
  `npx turbo login --sso-team=team-name` in order to get a cache token with the
  correct privileges.
</Callout>

Now, link your Turborepo to your Remote Cache:

```bash title="Terminal"
turbo link
```

Once enabled, make some changes to a package you are currently caching and run tasks against it with `turbo run`.
Your cache artifacts will now be stored locally *and* in your Remote Cache.

To verify, delete your local Turborepo cache with:

<PlatformTabs>
  <Tab>
    ```bash title="Terminal"
    rm -rf ./.turbo/cache
    ```
  </Tab>

  <Tab>
    ```bash title="Terminal"
    rd /s /q "./.turbo/cache"
    ```
  </Tab>
</PlatformTabs>

Then, run the same build again. If things are working properly, `turbo` should not execute tasks locally. Instead, it will download the logs and artifacts from your Remote Cache and replay them back to you.

Remote Caching on Vercel [#remote-caching-on-vercel]

If you are building and hosting your apps on Vercel, Remote Caching will be automatically set up on your behalf once you use `turbo`. Refer to the [Vercel documentation](https://vercel.com/docs/concepts/monorepos/remote-caching?utm_source=turborepo.dev\&utm_medium=referral\&utm_campaign=docs-link) for more information.

Artifact Integrity and Authenticity Verification [#artifact-integrity-and-authenticity-verification]

Turborepo can sign artifacts with a secret key before uploading them to the Remote Cache. Turborepo uses `HMAC-SHA256` signatures on artifacts using a secret key you provide.
Turborepo will verify the Remote Cache artifacts' integrity and authenticity when they're downloaded.
Any artifacts that fail to verify will be ignored and treated as a cache miss by Turborepo.

To enable this feature, set the `remoteCache` options on your `turbo.json` config to include `signature: true`. Then specify your secret key by declaring the `TURBO_REMOTE_CACHE_SIGNATURE_KEY` environment variable.

```jsonc title="./turbo.json"
{
  "remoteCache": {
    "signature": true, // [!code highlight]
  },
}
```

Remote Cache API [#remote-cache-api]

A Remote Cache can be implemented by any HTTP server that meets Turborepo's Remote Caching API specification.

Managed Remote Cache with Vercel [#managed-remote-cache-with-vercel]

[Vercel](https://vercel.com), the creators and maintainers of Turborepo, provide a managed Remote Cache that is fully compatible with Turborepo.

Using [Vercel Remote Cache](https://vercel.com/docs/monorepos/remote-caching) is zero-configuration and automatically integrates with [Vercel deployments](https://vercel.com/docs/deployments/overview) through the open-source [Vercel Remote Cache SDK](https://github.com/vercel/remote-cache).

Learn more about [Turborepo on Vercel](https://vercel.com/docs/monorepos/turborepo) or [deploy a template for free](https://vercel.com/templates?search=turborepo) to try it out.

Self-hosting [#self-hosting]

You can also self-host your own Remote Cache and log into it using the `--manual` flag to provide API URL, team, and token information.

```bash title="Terminal"
turbo login --manual
```

OpenAPI specification [#openapi-specification]

* [Human-readable viewer](/docs/openapi)
* [JSON](/api/remote-cache-spec)

At this time, all versions of `turbo` are compatible with the `v8` endpoints.

Community implementations [#community-implementations]

The Turborepo community has created open-source implementations of the Remote Cache.

* [`brunojppb/turbo-cache-server`](https://github.com/brunojppb/turbo-cache-server)
* [`ducktors/turborepo-remote-cache`](https://github.com/ducktors/turborepo-remote-cache)
* [`Tapico/tapico-turborepo-remote-cache`](https://github.com/Tapico/tapico-turborepo-remote-cache)
