GNAT Studio
What GNAT Studio is
GNAT Studio is AdaCore’s free desktop integrated development environment for Ada, SPARK, C, and C++ on Linux, macOS, and Windows. Its editor includes syntax highlighting, smart completion, code folding, refactoring, and automatic indentation. Built-in support covers GNAT, gcc, and make, while other command-line compilers and cross-compilers can be connected. Source navigation includes declaration and reference lookup, call trees, and package dependency browsers. Version control works with CVS, Subversion, Git, and ClearCase, with XML plugins for other systems. The integrated gdb debugger presents call stacks, variable values, and breakpoints. GNAT Studio connects with GNATcoverage, GNAT SAS, and SPARK analysis tools, and its Python API supports customization and plugin development. AdaCore describes the tools as suited to reliable, safe, and secure software, including safety-critical and mission-critical industries, and says it provides long-term support. Mobile development is not supported.
Who it suits
GNAT Studio suits developers building Ada, SPARK, C, or C++ software, especially in safety-critical or mission-critical settings. It is also suitable for teams needing integrated debugging, version control, analysis, and Python extensibility.
What it does well
- Free desktop IDE for three major operating systems
- Built-in compiler and make support
- Integrated gdb debugging views
- Multiple version-control systems included
- Python API for plugins and customization
What to know first
- No mobile development support
- Project Properties dialog deprecated from version 2026.1
- Downloads and guidance use GNAT Tracker
- Focused language support requires customization for others
Verdict
GNAT Studio brings editing, building, navigation, debugging, version control, and analysis into one free environment. Its strongest fit is software work using AdaCore tools and demanding reliability or safety requirements.
