RenderDoc is a frame-capture based graphics debugger, currently available for Vulkan, D3D11, D3D12, OpenGL, and OpenGL ES development on Windows, Linux, Android, and Nintendo Switch™. It is completely open-source under the MIT license.
RenderDoc is intended for debugging your own programs only. Any discussion of capturing programs that you did not create will not be allowed in any official public RenderDoc setting, including the issue tracker, discord, or via email. For example this includes capturing commercial games that you did not create, or capturing Google Maps or Google Earth. Note: Capturing projects you created that use a third party engine like Unreal or Unity, or open source and free projects is completely fine and supported.
Installation
There are binary releases available, built from the release targets. It's recommended that if you're new you start with the stable builds. Nightly builds are available every day from the v1.x branch here if you need it, but correspondingly may be less stable.
To install on windows run the appropriate installer for your OS (64-bit | 32-bit) or download the portable zip from the builds page. The 64-bit windows build fully supports capturing from 32-bit programs.
On linux only 64-bit x86 is supported - there is a precompiled binary tarball available, or your distribution may package it. If not you can build from source.
