A sampling JVM profiler that avoids safepoint bias for accurate performance analysis.
Honest Profiler is a sampling profiler for the Java Virtual Machine (JVM) that provides accurate performance analysis by avoiding safepoint sample bias. It helps developers identify true performance bottlenecks in Java applications without the distortions caused by traditional profilers that require threads to reach safepoints before sampling.
Java developers and performance engineers who need accurate profiling data for optimizing JVM-based applications and identifying performance bottlenecks.
Developers choose Honest Profiler because it provides more accurate profiling results than traditional JVM profilers by eliminating safepoint bias, which distorts performance measurements and can hide real bottlenecks.

Samples JVM threads without requiring safepoints, providing accurate profiling data free from traditional distortions, as per its core philosophy prioritizing accuracy over convenience.
Uses sampling techniques to minimize performance impact on running applications, ensuring profiling doesn't significantly skew results, as highlighted in the key features.
Works with standard Java Virtual Machines for profiling Java applications, making it versatile for various JVM-based systems.
Generates profiling data that can be analyzed to identify performance issues, emphasizing practical utility over flashy interfaces, per the README's description.
Requires downloading binaries or building from source, and manual JVM agent attachment via -agentpath, which is more involved than plug-and-play profilers.
Output is raw data without graphical tools, forcing users to rely on external software for analysis, increasing the learning curve.
As a specialized profiler focused on safepoint elimination, it has a smaller community and fewer integrations compared to mainstream options like JProfiler or VisualVM.
