Lume Data

A fast, lightweight, native database IDE for SQLite, PostgreSQL, MySQL / MariaDB, SQL Server and Oracle.

The SQL editor with results

Fast and light

Native C and SDL3: starts in a blink, stays idle at 0 % CPU, and keeps large result sets out of memory it does not need.

Big databases

Thousands of schemas and tens of thousands of tables, read in a few bulk queries, searchable, never all drawn at once.

Understand the structure

ER diagrams from real foreign keys, execution plans, object and table editors that review every change before it runs.

Private by default

Passwords in the OS secret store. Usage statistics off unless you turn them on. The AI sees nothing without your consent.
