Honest Profiler is a sampling profiler for the JVM implemented as a native agent, designed to avoid the safepoint sample bias that skews other sampling profilers. It runs with low overhead, making it suitable for profiling production applications.

Use cases

• profile a Java application in production with low overhead
• find CPU hotspots in a JVM application without safepoint bias
• diagnose performance bottlenecks in Java services
• sample JVM thread stacks accurately
• compare method-level CPU costs in a Java app

When to choose

• you need accurate sampling profiles of JVM applications without safepoint bias
• you want a lightweight profiler suitable for production use
• you prefer a simple agent-based profiler over heavyweight GUI tools

When to avoid

• you need a full-featured profiler with a rich GUI and allocation tracking
• you run a non-HotSpot JVM, since it relies on internal OpenJDK/Oracle JVM APIs
• you need actively maintained tooling with recent features
