SlimTune is a free profiler and performance analysis/tuning tool for .NET based applications, including C#, VB.NET, 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 an early beta, but it is fully functional and considered ready for use in most cases. Official releases are available and feedback is welcome. Both x86 and x64 targets are supported, but only sampling based profiling is available in the current release.

Development is active and version 0.3.0 has now been released, as of February 12, 2011. .NET 4.0 support has now been added.

SlimTune Profiler is completely free and open source for all uses. If you like using it, please consider donating. Development takes time and energy apart from our normal lives, and donations help ensure that the project will continue to thrive.
