Datadog dashboards allow users to create unified views of their application, infrastructure, and business data. To share these dashboards with others, users can generate a public URL or limit access to specific individuals by adding email addresses or company domains to an allowlist. Users can also control what data is shared by selecting time frames and template variables. This feature allows for the safe sharing of insights while safeguarding sensitive information. Additionally, Datadog's API enables programmatically managing and sharing public dashboards, making it easy to get started with a 14-day free trial.
