Fast, multi-threaded malloc() and nifty performance analysis tools
GPerftools (formerly Google Performance Tools) is a collection of a high-performance multi-threaded malloc() implementation, plus some pretty nifty performance analysis tools useful for creating more robust applications. These tools can be especially useful when developing multi-threaded applications in C++ with templates. Among these tools are TCMalloc, a thread-friendly heap-checker, heap-profiler and cpu-profiler.

Dynamic Interactive Views For Reverse Engineering. Div/er is a set of Eclipse Plugins that aid developers in understanding software. It uses dynamic analysis and reverse engineering to offer views and filters that aid comprehension and discovery.
cloc (Count Lines Of Code) counts, and computes differences of, comment lines, blank lines, and physical lines of source code in many programming languages. cloc is now being developed at https://github.com/AlDanial/cloc
OProfile is a low-overhead, transparent profiler for Linux, capable of instruction-grain profiling of all processes, shared libraries, the kernel and device drivers, via the hardware performance counters.
Windows prebuilt binary of QCacheGrind (better known as KCacheGrind)
The QCacheGrind branch of KCacheGrind compiled with the QT5 toolkit for use in Windows. This tool allows visualisation of profiling data in the callgrind-format. For Xdebug (PHP), version 2.2+ of the extension is recommended. Currently built and tested in Windows 7 for x86 and x64. Please go to https://sourceforge.net/projects/kcachegrind for the source. Description from the main project: KCachegrind visualizes traces generated by profiling, including a tree map and a call graph visualization of the calls happening. It's designed to be fast for very large programs like KDE applications.
SPE is a python IDE with auto indentation&completion,call tips,syntax coloring&highlighting,uml viewer,class explorer,source index,todo list,pycrust shell,file browsers,drag&drop,Blender support.Spe ships with wxGlade,PyChecker and Kiki.
A very simple implementation of C++ keyword sizeof for Java 5+. Developers can use it to know the real size of objects in memory.
The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.
Luke StackWalker is a GUI-based C/C++ source code profiler for Windows. It samples your application's stack while the application is running to find out where the application spends most of its time.
Python package to retrieve and manage data of the IMDb
IMDbPY is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.
The DaCapo benchmark suite is designed to faciliate performance analysis of Java Virtual Machines, compilers and memory management. It comprises a harness and a suite of open source real-world programs.
SLOCCount is an easy-to-use tool that counts Source Lines of Code (SLOC). It auto-determines the language(s) (inc. C, C++, Ada, Assembly, shell, COBOL, C#, Fortran, Haskell, Java, LISP/Scheme, Perl, PHP, Python, Ruby, SQL). It also estimates cost & time.
JRat is the Java Runtime Analysis Toolkit. Its purpose is to enable developers to better understand the runtime behavior of their Java programs. The term behavior includes, but is not limited to performance profiling.
KCachegrind visualizes traces generated by profiling, including a tree map and a call graph visualization of the calls happening. It's designed to be fast for very large programs like KDE applications.
mpiP is a lightweight profiling library for MPI applications.
A real Win32 extensible passive debugger
This project born a few years ago when I encountered a fatal bug on a production environment, unfortunately not replicable on my development machine. I spent many time finding a solution, using also freeware and commercial third-party tools and libraries, but none helped me because the bug crashed the process, and no of the above tools could be able to catch the exception before the process dying. Also, it was not possible to install a development environment onto the production machines, so the only solution was to develop a debugger which didn't need any user/developer interaction. I used many open source resources, then I decided to make the Bug Finder an open source project. It is built over a pluggable architecture to support other languages different from Borland Delphi (the one I used to develop my faulting application and the Bug Finder too). Here is the article http://www.codeproject.com/Articles/602794/Bug-Finder-a-real-Win32-extensible-passive-debugge .
JIP is a high performance, low overhead profiler that is written entirely in Java. JIP gives the developer the ability to turn the profiler on and off while the VM is running. You can also filter out classes and packages as well as control the output.
The tool helps to detect any resorces leaks (memory, handles etc.) in any Win32 application. Based on hooking of Win API calls: no source code required, attaches to any running process. Call stack available. Agregates leaks by origin.
Count lines of code, including comment and blank lines. Interactive GUI, or command line. End user may add new file types by editing config file. Supports any source language that uses characters to delimit comments, such as // or /* */.
FunctionCheck is a profiler for C/C++ programs, based on gcc V4.6.3+. Features are flat profile, cycles detection, call-graph, MIN/MAX time in functions, memory profiling, profiling control at execution...
Developer tool for automatic runtime tracing software errors with various resources. Number of resources virtually unlimited.
Map your path to clean data with an open source data profiling tool.
Map your path to clean data with Open Studio for Data Quality, the leading open source data profiling tool. Open Studio for Data Quality easily connects to hundreds of data sources and generates analysis to help define the next steps to clean data. Evaluate data quality against custom-defined thresholds, and measure conformance to internal standards such as SKU or external standards such as postal codes. Find out how to connect data with fuzzy matching or correlation analytics. Millions of downloads and a full range of robust, open source integration software tools have made Talend the open source leader in cloud and big data integration.
MySQL log analyzer and profiler. Extracts the most popular queries grouping them by their normalized form and shows the statistics for each group. Helps developers to recognize most frequently run queries to be able to optimize overall db performance.
Profiler4j is a simple-to-use CPU profiler for Java that supports remote profiling and on-the-fly configuration.
TimeDoctor is a tool to visualize execution traces of tasks, queues, cache behavior, etc. While originally targeting embedded media processors and includes specific features for analyzing audio/video streaming applications it has wider applicability.
