A desktop profiler for exploring local .NET memory and garbage collection.

• Follow heap usage, allocation rate, CPU time, elapsed time, and resident memory.
• Inspect GC events, generation counts, pause distributions, and tail latency.
• Explore live memory regions and replay a selected point or period.
• Capture heaps, browse types and objects, follow root paths, and compare captures.
• Launch an application with custom arguments and environment variables, or attach to a running process.
• Save recordings and reopen them for offline analysis.

Available measurements depend on the target runtime. Remote processes and ordinary .NET Framework applications are not supported.

Download the package for your operating system and architecture from the latest release.

Install the .NET 10 SDK. Building requires an Avalonia Pro Charts license supplied through the AvaloniaUILicenseKey environment variable.

dotnet run --project SatoriInsight/SatoriInsight.csproj -c Release

To create a self-contained Windows build:

dotnet publish SatoriInsight/SatoriInsight.csproj -c Release -r win-x64 --self-contained true -p:PublishTrimmed=true -o artifacts/publish

For NativeAOT, also install the Visual Studio C++ desktop build tools and Windows SDK:

dotnet publish SatoriInsight/SatoriInsight.csproj -c Release -r win-x64 -p:PublishAot=true -o artifacts/publish-aot

Choose Attach process or Launch process. Use Memory activity for live measurements and Heap inspector for captures.

See the user guide for the complete workflow and troubleshooting for connection, capture, and recording problems.

dotnet test SatoriInsight.slnx -c Release

Running the tests requires the .NET 8 and .NET 10 runtimes.
