Spoor gives you deep insight into your application's performance. Its three-part toolchain enables you to analyze your application down to the function call with nanosecond precision and includes:

  1. Compiler instrumentation to auto-inject trace events.
  2. A runtime library to capture and buffer events.
  3. Tools to process and visualize the traces.
