Dash0 ( https://www.dash0.com ) is an Open Telemetry native observability solution. It can ingest metrics and logs in standard Otel fashion. For user convenience it would be great to provide it out of the box including an input box for access key, ingress url and dataset.
There is a lot of documentation on the Dash0 integration hub ( https://www.dash0.com/hub/integrations ) how to integrate with platforms, and once Render has support Dash0 can add a documentation link easily. This for example is how you configure an Otel Collector for Dash0: https://www.dash0.com/hub/integrations/int_opentelemetry-collector/overview
