Callgrind uses runtime instrumentation via the Valgrind framework for its cache simulation and call-graph generation. This way, even shared libraries and dynamically opened plugins can be profiled. The data files generated by Callgrind can be loaded into KCachegrind for browsing the performance results. But there is also a command line tool in the package to get ASCII reports from data files without the need to use KCachegrind. KCachegrind is able to visualize output of other profilers like OProfile, a system-wide profiler for Linux using statistical sampling with hardware performance counters. There also exist converters for profiling output of Python, PHP and PERL.

The data files generated by Callgrind can be loaded into KCachegrind for browsing the performance results. This is a GUI/Visualization tool.

Valgui, an extensive interface for Valgrind

Alleyoop is a graphical front-end to the increasingly popular Valgrind memory checker for the x86 and x86_64 flavors of Linux using the Gtk+ widget set and other GNOME libraries for the X-Windows environment. <BR><BR> Features include a right-click context menu to intelligently suppress errors or launch an editor on the source file/jumping to the exact line of the error condition. A searchbar at the top of the viewer can be used to limit the viewable errors to those that match the regex criteria entered. Also included is a fully functional Suppressions editor

The MemcheckView GUI uses the Tool Gear viewer to display and organize Memcheck's output in a way that makes it much easier to examine the most-critical Memcheck warnings first. MemcheckView also displays the relevant source code for each warning and the source code can be viewed for the entire call chain, if desired. The MemcheckView package includes scripts (memcheck_all, memcheck) that provide an easy way to run Memcheck on parallel (MPI) and serial applications. Because Memcheck generates its output file on the fly while the application is running, the MemcheckView tool can monitor this output file and update the display continually. MemcheckView can also read a completed output file after the monitored application has exited.

MemcheckView is a GUI front end for Valgrind's Memcheck tool, which can detect a comprehensive set of memory errors, including reads and writes of unallocated or freed memory, reads of unitialized memory, and memory leaks.

Valkyrie is an open-source graphical user interface for the Valgrind 3.3.X line. Valkyrie uses the Qt widget library, and is based on Valgrind`s XML output capabilities. Valkyrie is designed for simplicity and ease of use, whilst allowing access to the full range of Valgrind command-line options. Currently, Valkyrie supports Memcheck only, although work is in progress to handle Cachegrind and Massif. Also included in Valkyrie is an auxiliary tool which can read XML outputs from multiple Valgrind (Memcheck) runs, merge them together into a single XML file, and optionally display the merged result in the GUI.
