This can be mitigated by utilizing the enterprise [caching]({{< relref "../../administration/data-source-management/#query-and-resource-caching" >}}) and/or rate limiting features.
Public dashboards allow you to share your Grafana dashboard with anyone. This is useful when you want to make your dashboard available to the world without requiring access to your Grafana organization. This differs from [dashboard sharing]({{< relref "../share-dashboards-panels" >}}), which either requires recipients to be users in the same Grafana organization or provides limited information, as with a snapshot.
You can see a list of all your public dashboards in one place by navigating to **Dashboards > Public dashboards**. For each dashboard in the list, the page displays the status, a link to view the dashboard, a link to the public dashboard configuration, and the option to revoke the public URL.
Available in [public preview](/docs/release-life-cycle/) in [Grafana Cloud Pro and Advanced](/docs/grafana-cloud). This feature will have a cost by active users after being promoted into general availability.
Please contact support to have the feature enabled.
Email sharing allows you to share your public dashboard with only specific people by email, instead of having it accessible to anyone with the URL. When you use email sharing, recipients receive a one-time use link that's valid for **one hour**. Once the link is used, the viewer has access to the public dashboard for **30 days**.
If a viewer without access tries to navigate to the public dashboard, they'll be asked to request access by providing their email. They will receive an email with a new one-time use link if the email they provided has already been invited to view the public dashboard and has not been revoked.
If the viewer doesn't have an invitation or it's been revoked, you won't be notified and no link is sent.
One-time use links use browser cookies, so when a viewer is granted access through one of these links, they will only have access on the browser they used to claim the link.
A single viewer cannot generate multiple valid one-time use links. When a new one-time use link is issued for a viewer, all previous ones are invalidated.
If a Grafana user has read access to the parent dashboard, they can view the public dashboard without needing to have access granted.

Public dashboards _should_ work with any data source that has the properties `backend` and `alerting` both set to true in its `plugin.json`. However, this can't always be
guaranteed because plugin developers can override this functionality. The following lists include data sources confirmed to work with public dashboards and data sources that should work, but have not been confirmed as compatible.
If you've confirmed one of these data sources work with public dashboards, let us know in our [Github](https://github.com/grafana/grafana/discussions/49253) discussion, and we'll mark it as confirmed!
We're excited to share this enhancement with you and we’d love your feedback! Please check out the [Github](https://github.com/grafana/grafana/discussions/49253) discussion and join the conversation.
If you're a Grafana Enterprise customer, you can use custom branding to change the appearance of a public dashboard footer. For more information, refer to [Custom branding](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/configure-custom-branding/).
