A privacy-first Postgres client that runs in your browser. Paste a connection string, browse schemas, run SQL, visualize relationships, watch database health — no account, no telemetry, no server-side query history. The connection string lives only in sessionStorage and is sent server-side only when a query runs; TLS is strict by default with sslmode=no-verify as an explicit escape hatch. Next.js 16 App Router + React 19 + pg on Vercel Fluid Compute, 15-second statement timeout, 200-row result cap.
