SlimTune is a free profiler and performance analysis/tuning tool for .NET based applications, including C#, VB.NET, IronPython, and more. It provides many powerful features, such as remote profiling, real time results, multiple plugin-based visualizations, and much more. The source code is available under the terms of the MIT License.

SlimTune is currently in the prototyping phase of development, but a preview release is available for testing and feedback is welcome. Both x86 and x64 targets are supported, but only sampling based profiling is available in the release.

Note: Development is currently on hold until about January, due to personal issues. Rest assured, there is plenty more to come!
