What is SQL Developer?
Oracle SQL Developer (often shortened to just SQL Developer) is a free integrated development environment for working with databases on Windows. First released by Oracle in 2005, it's become one of the most widely-used database IDEs on Windows — a multi-database SQL client that connects to Oracle, MySQL, PostgreSQL, SQL Server, SQLite, and MariaDB from one interface, lets you write queries, browse schemas, and manages data without switching tools.
It's free for personal and commercial use, with no Oracle account required to download. The same .zip ships from Oracle's CDN whether you grab it here or from oracle.com directly.
// who it's for
Backend developers building applications, database administrators managing production systems, and data analysts running ad-hoc queries — anyone who works with SQL on Windows 10 or Windows 11 and wants the best free SQL client for the job, without subscription fees, account walls, or login friction.

How SQL Developer Works — Step-by-Step Demo
Three minutes from launching the app to running your first query. Here's what that flow looks like inside the IDE — same flow whether you're connecting to Oracle, MySQL, PostgreSQL, or SQL Server.
~/sql-developer/demo3 panels
1. The Connections panel. Green + opens the New Connection dialog. Pick a database type from the tabs (Oracle, MySQL, PostgreSQL, SQL Server, SQLite), fill in host, port, username, password. Hit Test, then Connect — the connection appears as a tree of schemas, tables, views, and indexes.
2. The worksheet. Alt+F10 opens an editor pane. The status bar at the bottom shows which connection it's bound to. Type or paste SQL — auto-complete suggests table and column names from the live schema:
SELECT table_name, num_rows FROM user_tables ORDER BY num_rows DESC FETCH FIRST 10 ROWS ONLY;
Ctrl+Enter runs the current statement. Results land in a grid below the editor — sortable, filterable, exportable to CSV, Excel, JSON, or pasteable INSERT statements.
3. Save and pin. Ctrl+S writes the worksheet to a .sql file. Right-click the connection in the tree to pin the worksheet — it'll re-open automatically next time you connect.
