SQL Client - PostgreSQL, MySQL

SQL Client that runs on a phone. Connects to PostgreSQL and MySQL, plus MariaDB through the same MySQL driver. Save a connection profile and use it whenever the database needs a quick check.

SSH tunnel is available in Pro. Reach internal databases behind a bastion with a single private key, no desktop forwarding required. Passwords and key files stay in the device secure storage, never written to disk as plain text.

■ Browser

Browse tables, views, procedures, and functions in a collapsible tree. Tap a table and the detail splits into four subtabs: Data, Columns, Indexes, DDL. Data tab edits rows inline, respects NOT NULL and FK hints, and exports to CSV or Excel. Columns tab runs ALTER TABLE ADD COLUMN through a form and lets you drag-reorder columns on supported engines. DDL tab shows the CREATE statement with colored SQL syntax and a copy button.

■ Query

Multi-tab SQL editor. Split work across tabs, keep context, write with table and column autocomplete driven by cached metadata. Destructive statements (DROP, DELETE, TRUNCATE, ALTER) trigger a confirm dialog before execution. Row cap is configurable (20, 50, 100, 500, or custom). Result sets export to CSV or Excel.

■ History

The last 500 executions are kept locally. Tap any row to rerun it or load it back into the Query tab.

■ Connection panel

Tap the connection name in the top bar to see every database on the same server. Switch immediately, create a new database, or force-refresh cached metadata when it goes stale. MySQL and MariaDB switch via USE; PostgreSQL reconnects to the selected database.

■ Security

The SQL client stores credentials in the device secure keystore. Enable Face ID or fingerprint lock and the app re-authenticates every time it returns from background.

■ Interface

Light and dark themes with equal polish, five languages (Korean, English, Spanish, Chinese, Japanese), and landscape split view (tree on the left, detail on the right). Theme and language changes apply without restart.

■ Pro

SSH tunnel, unlimited connection profiles, unlimited query tabs, no ads, and unlimited row edits come with a one-time Pro purchase.

MonoDB is a mobile SQL client for PostgreSQL and MySQL, with MariaDB supported on the same driver. Use it for the quick lookups and fixes that do not justify opening a laptop.
