JetBrains dotMemory review
A focused .NET memory profiler for finding leaks, allocation issues, and memory pressure.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
JetBrains dotMemory is a desktop memory profiling tool for .NET applications written in C# and VB.NET. It is aimed at developers investigating memory leaks, excessive allocations, garbage-collection behavior, and other memory-management problems. The product supports Windows, macOS, and Linux, with profiling modes centered on sampling and memory analysis rather than broad application performance profiling.
Its strongest area is the depth of its memory workflow. dotMemory can collect sampled and full allocation data, capture memory snapshots, compare snapshots, and show a real-time memory timeline. Automatic memory-issue inspections help identify common problems, while memory traffic analysis adds context around object activity over time. Raw process-dump analysis extends the workflow beyond live profiling. These features make dotMemory a strong fit when the primary question is why memory grows, which objects remain reachable, or where allocations are coming from.
The surrounding toolchain also suits .NET teams that already work in JetBrains Rider or Microsoft Visual Studio. ReSharper integration, command-line profiling and automation, and the dotMemory Profiling API support IDE-based investigation and repeatable workflows, including remote scenarios. A 30-day free trial is available, but there is no free plan. Teams that need focused memory diagnostics should consider dotMemory; teams seeking one profiler for CPU, memory, and thread analysis should choose a broader alternative.
JetBrains dotMemory pros and cons

- Rider, Visual Studio, command-line, and API integration support automation
- Where it doesn't
- No CPU profiling for investigating processor-heavy code
- No thread profiling for diagnosing threading behavior
- Paid product with no free plan
