TOra
TOra is a free, open-source SQL IDE for Oracle, MySQL, and PostgreSQL database development and administration.
What is TOra?
TOra, short for Toolkit for Oracle, is a mature open-source database IDE originally designed for Oracle but now supporting MySQL and PostgreSQL. It has been in development since the early 2000s and remains actively maintained, with steady updates reflecting its stability and niche relevance. Built using Qt, it runs natively on Linux and integrates well with desktop environments.
It's best suited for database developers, DBAs, and system administrators who work regularly with Oracle PL/SQL or need cross-database support in a lightweight tool. Users managing production or development databases will appreciate its debugging and schema browsing capabilities. It’s particularly helpful when you need a native Linux alternative to Windows-only tools.
Compared to Toad for Oracle, TOra offers a similar set of features—especially in SQL editing and PL/SQL debugging—but with a simpler, less polished interface. While Toad has more wizards and automation, TOra feels more direct and less cluttered. Performance is solid on local or low-latency connections, though it lacks cloud integration and modern UI refinements.
Best for: Developers and DBAs who need a free, native Linux tool for Oracle PL/SQL debugging and database administration.

Windows programs TOra replaces
ToadTips for Windows users
If you're used to Toad, expect fewer visual helpers and templates. TOra doesn’t import Toad settings or connections directly, so you'll need to reconfigure them. Keyboard shortcuts differ—spend time in the preferences to remap if needed. Workflow is more manual, but the core SQL and debugging functions are there. Exported data formats (CSV, SQL) are compatible, but reports won’t transfer.
