A toolsmith for GNOME-based applications

About Builder

A tool to help you write and contribute to great GNOME-based applications.

Global search

Search for files, classes, and functions with lightning fast fuzzy search.


Explore APIs used by your project with auto-completion for C/C++, Python, Rust, and Vala. For languages without native support, ctags integration is provided.

Mini Map

Never lose your place in large code bases thanks to Builder's source code map.

Documentation at your fingertips

Quickly reference documentation where you need it without losing focus.

Edit side by side

Have as many editors as you need. Side-by-side, one atop another, or whatever combination you're comfortable with.

Starting a new project is a snap

Feeling adventurous or just want to learn? Try creating a new project and push your creative boundaries!

Git Integration

Already have a project for which you want to contribute? Simply enter the URL of the git repository and you're on your way.

Application Profiling

Keep your application running fast with Builder's integrated profiler, powered by Sysprof.

Application Debugger

Builder includes a modest debugger to help you track down those troubled logic errors.

Take Control with the Command Bar

Command line interfaces are great so Builder bakes one right in. A lot of Builder's features can be alternatively accessed via the command bar, and it even has tab completion!

Tweak all the things!

We know you're as creative with your preferences as you are with your code so Builder makes tweaking things quick and easy. You can search across application preferences and plugins with just a couple of key strokes.
