Five windows.
Zero clarity.
You're debugging a slow join at 2 AM with pgAdmin, DBeaver, Robo 3T, a psql terminal, and DataGrip all open — each with its own connection state, keyboard shortcut, and failure mode.

Engineers who've been
in that 2 AM debug session.
"Replaced DBeaver and two separate Mongo clients in one afternoon. QueryVault's explain plan alone saved us three hours on a bad index last Tuesday."
"We went from five database GUIs to one. Our staging/prod parity issues dropped by 60% because everyone's running queries in the same tool."
"The read replica routing is the feature I didn't know I needed. QueryVault automatically sends my SELECT queries to replicas. My primary DB load dropped 40%."
"I debug slow joins at 2 AM more often than I'd like. Having the EXPLAIN plan right next to the query editor, in the same dark-mode workspace, is genuinely calming."
