Running one query across databases
Ask the same question of staging and prod at once and see exactly where the answers differ.
Open Compare, pick a project, and write one statement. AddisDB runs it against the databases you select — up to thirty in a project — and diffs the results side by side. This is the “does staging match prod?” question, answered in one go.
Reading the diff
Rows that match across every target are collapsed so the differences stand out. A database that errors or times out is reported as itself rather than silently dropped, so a missing answer is never mistaken for a matching one.
Safety still applies per connection
Each target is judged on its own settings. A statement that would write is blocked on the connections marked read-only even if it is allowed on the others — one comparison does not lower anyone’s guardrails.
