Connect a read-only database account and create a small set of clearly named metrics. Verify results against known totals before sharing dashboards, then document filters and date conventions. Assign responsibility for permissions, upgrades, and backups, and review commercial feature requirements before standardizing the organization on the free edition.
This is best suited to teams sharing internal business dashboards. Before committing a larger project, account for these trade-offs: self-hosting requires operational work; advanced commercial features are excluded.
