Masküi is an enterprise desktop application for SQL Server database exploration, visual querying, data export, and reversible data masking. The public site creates DeviceSeal request files for licensing support, while the current desktop build keeps audit history as local troubleshooting data. No cloud, no accounts.

An offline desktop app (Tauri) for working with SQL Server data safely.
Browse servers, databases, schemas, and tables from a fast desktop UI.
Build and run queries visually and inspect results without writing boilerplate.
Export query results for downstream use, on your own machine.
Format-preserving masking that authorized operators can reverse — protect sensitive fields without breaking shape.
Record important app actions locally so support can trace connections, queries, masking, exports, settings, and diagnostics.
Runs locally on Windows and Linux (macOS planned) — nothing leaves the machine.
Pick a request form. It generates a small request file in your browser — you email it to us, and we process it offline.
Choose from re-download, new capacity, renewal, upgrade, operational, or support.
A DeviceSealCustomerRequest.v2 JSON file is created locally — no data leaves the page.
We validate it against our records and act on it offline. Re-downloads are safe — a license only opens on its bound device.
